Veavage

Veavage (pronounced vee-vig)

(1) The expanse of bare skin a woman displays when wearing a dress (or top) with a neckline cut in a deep (often called plunging) “V”, the vertex (the bottom junction where the two diagonal strokes meet) typically reaching the midriff but the lines can intersect as low as the waist or even the hipline.  As a design, it’s the familiar “V-neckline” taken to its logical conclusion although much the same can be achieved with what technically are “scalloped necklines” or “U-plunges”.

(2) As “veavage dress”, “veavage top” etc, a garment so designed.

2026 (2010 for an earlier, now extinct purpose): A portmanteau word, the construct being ve(e) + (cle)avage.  In English, vee had a long history as an illustration of the pronunciation for the letter “V” but it was in US English in the mid-1860s it began widely to be used in building, architecture and engineering to describe various structures, components or configurations.  Because of the attractive properties of triangles, the “V-shape” would for millennia have been part of the man-made environment (indeed, it exists in botany, animals and geology) but the form “vee” appears in this context to have been well documented only from the mid-nineteenth century and use as a direct substitute for the Latin script letter “V/v” is documented from 1869.  In internal combustion engines, “vee” seems first used of piston engines in this configuration by 1915 although the first known V-twin was built in 1889 and the first V8 in 1903.  Although common as a descriptor of shapes or physical objects, the more abstract re-purposings included (1) a polyamorous relationship between three people, in which one person has two partners who are not themselves romantically or sexually involved and (2) in the (male) gay community, “a Vee” is a verbal shorthand for “a versatile” (one who is not exclusively “a top” (or “pitcher”) or “a “bottom” (or “catcher”) but indulges in both practices.  The coining is too recent for derived forms to have emerged but the possibilities include veavaged, veavaging and veavesque.  Veavage is a noun (and potentially a verb & adjective); the noun plural is veavages.

Of Vee

Cricket's “vee”, recommended for “high-percentage” shots.

Teevee was a respelling of the abbreviation TV (for television) so the two are synonymous but the former (with its four superfluous vowels) survived only as a “niche word”.  In the era between the early post-war years and services like YouTube and its many imitators becoming mainstream, a “teeveen” was a young person who “watched too much TV”.  In SF (sci-fi, science fiction) a three-vee was a screen able to display in three-dimensions; authors used also “3v”, “tri-v” “tri-vid”, “tri-d”, “trideo” & “tridim” and although they didn’t show quite the disdain for capitalization as later would emerge in the business of computer hardware & software, the literary preference seems to have tended to the lower case.  The humorists of the 1980s used a mix of upper and lower when creating shorthand critiques of the US cable television channel (1981) MTV (pronounced emm-tee-vee and an initialism of “Music Television”).  Claiming the channel’s programming was banal, they conjured up “eMpTyV”, “empty-vee”, “Empty-V”, “Emptyv”, “emptyV” & “eMpTy V”, all to be pronounced emp-tee-vee.  That was a variant of the technique used to produce rebus abbreviations (in structural linguistics technically a “gramogram”) such as “NRG” for “energy” or “XLR8” for “accelerate”.  All worked best when written because although non none possessed classic phonetic assimilation, sloppiness in real world use, sloppiness in pronunciation probably often rendered the sound of emm-tee-vee vs emp-tee-vee indistinguishable.  In cricket, the “vee” describes the arc of the field, forward of the batter, from cover to midwicket, in which drives classically are played (a shape better visualized as an “L” because, like many “vee” engines, the vertex is a 90^o angle) and coaches still instruct batters to “play in the Vee” because that’s most productive for “high percentage” (ie more runs, fewer dismissals) but in the newer, shorter forms of the game, that’s now less relevant.  Whether “veagage” catches as jargon for coaches advocating “playing in the Vee” remains to be seen.

Playing in the vee.  Australian cricketer Ellyse Perry (b 1990) with the trophies of the two Cricket Australia (the new name for the old Board of Control) Cricketer of the Year awards she won in 2023 (in the T20 and ODI (One Day International) categories). Note the splendid shoulder & upper-arm muscle definition.

In typography & computing, typography, a “vee” was a unit of vertical spacing, typically corresponding to the height of an ordinary line of text.  In machinery, a vee-belt (often as v-belt) was a drive-belt of reinforced rubber or other compounds which was mounted on drive wheels or pullies, the name gained from the V-shaped cross-section (some with notches which were called “toothed belts”).   “Vee Dub” was a slang term for a vehicle produced by Volkswagen (VW) and a Vee Dubber was a VW fan boy.  A veejay was the host of a television programme who presented videos, based on the earlier “DJ” (disc jockey, a radio presenter who introduced music broadcast by playing tracks from discs, a use which has survived many DJs now operating without discs).  A VJ was also a “vertical joist” which was a length of timber used as a vertical upright for structural support.  In vulgar slang, “VJ” also was a term for the vulva or vagina and Urban Dictionary has an entry from 2010 listing “veavage” with the construct v(aginal) + (cl)eavage (ie the infamous “camel toe”) but the use didn’t then catch on.  A veep is “a vice-president” but that form is now almost wholly associated with the VPOTUS (vice-president of the US).  

Of Veagage

Actor Keira Knightley (b 1985) in a classic black veavage dress, illustrating how the emphasis has shifted to the skin rather than the cleavage which was the traditional focus of the deeper “V-necklines”, things now done with “a hint”: less is more.

With due acknowledgment of the use in 2010 (documented by Urban Dictionary), which never gained traction, “veavage” is a new word but it doesn’t describe a wholly new though the emphasis genuinely is a variation of an old theme.  Veagage is a deeply plunging V-shaped cut in a garment which displays some of the chest & midriff down sometimes as far as the hipline although most stop at the waist.  Obviously something best worn on red carpets or for photo-shoots in controlled environments (light, surface irregularities, wind-speed & direction, crowds etc), it differs from the traditional approach to the chest in that emphasis is on the skin rather than the breasts, the veagage look de-emphasising those glands so the cut is ideal for those able to summon much of a cleavage only with structural engineering such as a bra or Hollywood Tape (better known by the more evocative “tit-tape”).  So it can be a good, eye-catching choice for those without the anatomical advantage demanded by outfits optimized for “peak cleavage” but it has been criticized as a form of “privilege-dressing” which is said to carry the whiff of “white feminism”.

Controversial and not accepted by all as something “real”, “white feminism” is said to be a fork of feminism concerned almost exclusively with concerns of white, middle-class, cisgender, and heterosexual women, the problems of women not ticking those boxes ignored.  It’s thus an individualistic strain of feminism which aims to maximize one’s advantage within existing systems rather than seeking systemic reform for the collective benefit.  From there it may seem a bit of a leap to veagage as marker of political exclusion but it’s true there may be a link (the notion of v=(c+p) (cleavage + privilege = veavage)) in that while it accommodates at least some on the spectrum of breast size, slenderness is essential and for those not genetically lucky or disciplined, there are the GLP-1 (Glucagon-like peptide-1) drugs and overwhelmingly, they remain a tool for those who are (in global terms) “rich”.

Lindsay Lohan, Olympus Fashion Week, Bryant Park, Manhattan, February 2006.  Although more associated with the traditional use of the V-neckline, this is archetypical veavage.

Unlike some “straight-line letters” such as “W” or “X”, the letter “V” is almost always rendered with straight lines but fashion editors are more forgiving than geometers (since the time of the third century BC mathematician of Ancient Greece Euclid the historic term for mathematicians whose primary research field was geometry) who would insist the plunging neckline of Ms Lohan’s red dress is not a “V” but a “curvilinear angle” (an angle with sides of curves rather than straight line segments).  In elementary geometry, the classic angle consists of two straight rays meeting at a vertex, whereas in a curvilinear angle the sides are arcs or other curves intersecting at a point.  In fashion, up to a certain stage, a “curvilinear angle” is still a “V-neckline” because the visual effect is so close but, as the curves become more curved, at some point the cut becomes closed to a “scallop” or “scoop” and is so described.

Model & writer Hari Nef (b 1992) in Schiaparelli.  Like the trade-off in warship design between armor & speed, less gland means more veavage so those not best suited to cleavage in a V-neckline have an alternative.

So with V-shaped necklines descending to the navel (or a little beyond) hardly a novelty given their not infrequent appearances over the last two-decades-odd, why did the word “veavage” suddenly make an appearance in 2026?  The obvious answer is of course “click-bait” but that’s not of necessity a bad thing because, in a sense, that trick is supply anticipating demand and there are aspect of the internet (which at least for now seem to have become structural) that should arouse more concern.  It’s a good word and a welcome addition to the fashion business; presumably an industry commentator noted a spike in the “deep vee” showing up on the catwalks or red carpets and, things “on trend” needing a tag, conjured up (or re-purposed) “veagage”.  The speculative link to the look becoming more prevalent because GLP-1s have rendered more women with physiques suitable for such things is intriguing but wholly impressionistic and trends anyway tend to wax and wane in its niche, veagage seems here to stay.

Of Cleavage

Actor Sydney Sweeney (b 1997) with a more traditional implementation of the V-neckline.  Empirically, this look is likely to remain the dominant approach although, as it has for years, the veavege will run in parallel. 

The noun cleavage seems first to have appeared in the 1805, the construct being cleave + -age.  It was used first in geology and mineralogy to describe “the tendency (of rocks or gems) to break cleanly along natural fissures” with the generalized meaning “action or state of cleaving or being cleft” emerging in the mid 1860s.  Although the artistic record confirms the popularity of the look had over the centuries come and gone in the cyclical way fashion behaves, use of “cleavage” in the sense of the “the hollow between a woman's breasts (usually when artificially supported), especially as exposed by a low-cut garment” appears not to have been seen in print prior to the use in an article in Time magazine discussing the (nominally) self-censorship codes of practice adopted (not entirely willingly) by the Hollywood film studios.  In finding a single word, Time’s editors proved good practitioners of journalistic succinctness because what they were reducing to a word had been described in the industry’s bureaucratese as “the shadowed depression dividing an actress' bosom into two distinct sections.”  Cleavage caught on although to this day the more up-market fashion glossies still hanker after the French borrowing décolletage.

Variations on a theme of Vee: Lindsay Lohan (during blonde phase) in V-neckline, V Magazine's Black and White Ball, Standard Hotel, New York City, September 2011.

Cleave was in use prior to 950 and was from the Middle English cleven, from the Old English strong verb clēofan (to split, to separate), from the Proto-West Germanic kleuban, from the Proto-Germanic kleubaną, from the primitive Indo-European glewb- (to cut, to slice).  It was a doublet of clive and cognate with the Dutch klieven, the dialectal German klieben, the Swedish klyva, the Norwegian Nynorsk kløyva; it was akin to the Ancient Greek γλύφω (glúphō) (carve) and the Classical Latin glūbere (to peel).  Given the time and place of cleave’s emergence, etymologists suspect the original sense was likely related to the handling of timber (ie to split or divide by or as if by a cutting blow, especially along a natural line of division, as the grain of wood).  The suffix -age was from the Middle English -age, from the Old French -age, from the Latin -āticum.  Cognates include the French -age, the Italian -aggio, the Portuguese -agem, the Spanish -aje & Romanian -aj.  It was used to form nouns (1) with the sense of collection or appurtenance, (2) indicating a process, action, or a result, (3) of a state or relationship, (4) indicating a place, (5) indicating a charge, toll, or fee, (6) indicating a rate & (7) of a unit of measure.  The French suffix -age was from the Middle & Old French -age, from the Latin -āticum, (greatly) extended from words like rivage and voyage.  It was used usually to form nouns with the sense of (1) "action or result of Xing" or (more rarely), "action related to X" or (2) "state of being (a or an) X".  A less common use was the formation of collective nouns.  Historically, there were many applications (family relationships, locations et al) but use has long tended to be restricted to the sense of "action of Xing".  Many older terms now have little to no connection with their most common modern uses, something particularly notable of those descended from actual Latin words (fromage, voyage et al).

A veavage can of course be an eye-catching billboard and the obvious stuff to advertise is jewellery (left).  Model Bella Hadid showed how it could be done with scalloped neckline, wearing a black Schiaparelli gown (cut for the purpose with an untypically wide aperture) used to frame a sculptural piece, fashioned in gilded brass to resemble an anatomical cast of the lungs’ bronchi (the paired series of cartilaginous, tube-like airways branching from the trachea into each lung, acting as the primary passage for air distribution).

Golfer and multi-media personality Paige Spiranac (b 1993).

Despite the etymological implication, a veagage is about the display of skin and is not dependent on being framed in a “V” but the point about it is the de-emphasis of the breasts (and thus the cleavage).  What Paige Spiranac wore to Sports Illustrated 60^th anniversary event could (with some strategically placed double-sided tape) be used for the purpose but technically the ensemble was a variant of the “curtain reveal” motif (in “open” mode).  Whether it would produce a veagage or a cleavage would depend on the wearer.

In the 1980s, US political scientists used the term “cross-cutting cleavages” to describe what had been revealed as a phenomenon both increasing frequency and spreading demographically and geographically.  The term referred to a social structure in which different lines of division in society intersect rather than coincide (ie groups created by one social division are mixed across the groups created by another division, instead of aligning with them).  In the West, as an identifiable trend, this likely was something that had ebbed and flowed since the decline of feudalism but in the post-war years it became of interest to political scientists because it was clearly something influencing social conflict and voting behaviour, the issue-by-issue alignment within and between sectional classifications no longer as predictable.  What had become obvious was the membership of groups in one dimension was overlapping with multiple groups in another.

Because the veagage effect is most effective when at its most 2D (two dimentional), when that’s what’s wanted, the usual approach is to have the fabric cling to the skin (with double-sided tape as required) but V-necklines can be executed differently for other outcomes; the double-sided tape is still applied but in different places.

Overlap was not new in that “coalitions of interest or concern” had long been known to be subject to these “crossovers” (especially at the margins) but in the days before big machine databases transformed this into something political parties could not merely manage but exploit, it was a genuine problem.  The more optimistic academics suggested cross-cutting cleavages operated to stabilize democracy because, with individuals simultaneously belonging to many groups (class, religion, occupation, region), the overlap prevented politics from collapsing into a series of polarized conflicts, what some called “the Balkanization of society”.  The argument was the behaviour compelled political parties to build broad coalitions across multiple groups, moderating the inherent tendency to conflict and reducing the likelihood of groups becoming the captives of extremist positions.  There may have been something in this because in the US, between the 1930s & 1980s it was those broad (notably geographical) coalitions which characterized US politics; political conflict didn’t go away but it was diffuse rather than binary.  In operation, that mid-century model was very different from Europe.  There, “cleavage theory” was a descriptive model of the way several centuries of major (and often bloody) social conflicts (cleavages) worked finally as the catalyst for state formation and industrialization.

Wonderbra New Deep Plunge Bra.

The manufacturers have for decades noted the appeal of the V-neckline and have created a vibrant market in accessories and devices.  Up to a point, the conventional cantilever method works but there are practical limits.  However, while physics can’t be fooled, optics can and what Wonderbra did for the New Deep Plunge Bra was replace the conventional fabric-covered gore with one of translucent plastic, thus creating a “one skin tone fits all” fitting.  Except on close inspection, it was close to invisible.

The West (and especially the US) is of course now in the age of “mega identity politics” and the parameters of those identities are in the effective control of a relative handful of extremists (“absolutists” or “purists” the more polite forms) who have the historically unique (in reach, immediacy and scope) platform of social media set agendas and cancel transgressors; even in groups originally created because of oppression, now routinely oppress heretics who depart from the orthodoxy.  This does not imply political parties have become “single issue” operations but substantially they are tending towards the ideologically monolithic as aggregations of what scholars have labelled “stacked identities” and the process of “purification” is not organic: within the party machines, those seeking absolute control undertaking purges, witness the gradual preponderance within the Republican Party of the MAGA (Make America Great Again) over those condemned as “pseudo conservatives”, the RINOs (Republicans in Name Only).  In the Democratic Party, identities have come to trump (the verb) all else and few now dare to raise the matter of trans-females competing in sporting competitions for women because the “trans rights” have become a litmus-paper test of adherence to orthodoxy.  So, the machinery which decades ago assembled coalitions of interest now creates tribes with much of what that word implies, political scientists sanitizing things a bit with the tag “affective polarization”.  While the cause-and-effect processes in all this were not wholly binary, it has rendered conflict now identity-based in that conflicts are between world views and way of life rather than the minutiae of policies.

Ultradeep U-Plunge.  Where the vee didn't plunge so deep, a more conventional construction could be used although many did include "clear" shoulder straps, made of the same kind of material as sometimes used for the gore.

So, whereas the national and state legislatures once thrashed things out and often managed to achieve compromises, that’s now less common because a “compromise” is seen as a “surrender” or “betrayal” and the consequences for that included being “cancelled” or “primaried”, two weaponized devices able successfully to be deployed by a remarkably small number of committed extremists.  None of this is any secret but there’s no obvious solution because the simple fix (mass active participation of the electorate (the so-called “sensible centre”) in party politics) has little appeal for either the voters or those running the party machines, both groups for their own reasons appalled by the notion.  The days are gone when the Republicans had their “moderate” faction (the so-called Rockefeller Republicans (named after Nelson Rockefeller (1908–1979; US vice president 1974-1977 and who earned immortality by having “died on the job”) and the Democrats their “Southern Conservatives” (the so-called “Dixiecrats” in the not always attractive tradition of figures like old Strom Thurmond (1902-2003; senator for South Carolina 1954-2003)).  By the 2020s, that overlap has almost completely disappeared with politics now more polarized than at any time in living memory and political scientists lament the shift but they should recall a remark in the paper Toward a More Responsible Two‑Party System (1950), published by the APSA (American Political Science Association): “The two parties do not differ enough.”  Expanding on that, the authors added: “Alternatives between the parties are defined so badly that it is often difficult to determine what the election has decided even in broadest terms.”  As a critique this came to be called the “Tweedledum & Tweedledee problem” (two characters in Through the Looking-Glass, and What Alice Found There (1871) by Lewis Carroll (pen name of Charles Lutwidge Dodgson (1832–1898)) who had different names but look the same and behave in identical ways.

Das U-boob theory.

Orla U-Plunge Backless Adhesive Bra in Black (left) and Salma Hayek (b 1966, right) demonstrates the uvage, Evening Standard Theatre Awards, London, November 2015.  Orla's “adhesive” is a reference to the side panels which adhere directly to the skin (using the same technology as surgical tape), allowing the bra to a achieve a “backless” effect.  Because the cut of some gowns obviously is a “U” rather than a “V”, the fashionistas might feel compelled to add “uvage” (pronounced yoo-vig, the construct being u + (clea)vage)) to the lexicon because, if the two styles appear together on the catwalk, single-word differentiation might be helpful.

Heart & wedge: Luciana Heart Cut Out Long Sleeve Mini Dress in black (left) and French content creator & author Léna Mahfouf (aka Léna Situations, b 1997), Academy Awards ceremony, Los Angeles, March 2026.

However, although tempting, being too specific about geometry might lead to a proliferation of terms because designers have proved inventive in the shapes of the “cut-outs” in gowns.  A heart shape could perhaps attract “carveage” (pronounced kar-vig, the construct being car(diac) + (clea)vage) and an inverted vee could be called a “wedgeage” (pronounced wed-jige, the construct being wedge + (cleav)age).  In formal logic, the wedge symbol (∧) represents “AND” (the logical conjunction); in its opposite orientation (V) the symbol is called a “vee” and represents logical “OR”.  So, imposing precision may be a needless solution to a non-existent problem and the industry seems likely to continue to tolerate what Winston Churchill (1875-1965; UK prime-minister 1940-1945 & 1951-1955) in 1906 called “terminological inexactitude” (used as a euphemism for the un-parliamentary “lie” and coined because in the House of Commons, Mr Speaker had long since proscribed use of  “mendacious”).  Beyond the "V", "U", "heart" and "wedge", there are may more shapes so veavage seems likely to serve as a generic for what’s produced by all.

In 1950, the conclusion was there was “too great a degree of internal heterogeneity” in that, housing both liberal and conservative wings, the forces tended to “cancel each other out” with the consequence being party programmes which were vague and often similar, meaning voters found it hard to identify clear policy alternatives.  In a sense, that took the “science” out of “political science” and the academics didn’t like it, preferring clear battle-lines (Roundheads vs Cavaliers; democracy vs fascism and such) for without clear differences, there really was no politics; all that remained was the dreary business of management.  In retrospect, the APSA likely agrees people should be careful what they wish for and and many contemporary political scientists now argue the system has moved too far in the opposite direction, producing intense polarization and reinforcing cleavages.  Still, we may as well get used to the system because most conclude it’ll likely get worse before it gets better.

Of Vee Engines

Ford FE V8 (left) and Y-Block (right). The frontal view of the FE engine illustrates both why the configuration is called a “vee” and why it would have been understandable had the 90^o engines been dubbed “L8s”.  Ford’s first OHV (overhead valve) V8 (for pick-up trucks & passenger vehicles) picked up the nickname “Y-Block” because the skirt extended to an unusually low point, the additional cast iron thus recalling the tail of the letter “Y”.

The “V” in certain engines (V4, V8, V16 etc) is a reference to the angle of the banks of the block’s cylinder banks when viewed along the line of the crankshaft and the configuration in ICE (internal combustion engines) was used within half-a-decade of the “first” automobile appearing on the roads in 1886, Wilhelm Maybach (1846-1929) and Gottlieb Daimler (1834-1900) in 1889 installing a 565 cm³ (34 cubic inch) V-twin (ie two cylinder) unit in the Daimler Stahlradwagen (steel-wheeled car).  The Stahlradwagen’s V-twin used what was, by the standards of which would follow, a very narrow angle for the vee (quoted usually a 17^o but listed also “in the 20^o class”) and over the years, “vee” engines have appeared with angles ranging between 12.5 and 180^o (while the latter may seem a contradiction in terms, the 180^o vee (e a straight line) is accepted engineering jargon).  The first V8 (1903) & V12 (1904) appeared in what was for each the “ideal vee angle” (90 & 60^o respectively), the number dictated by desire for the even firing intervals to ensure the smoothest power delivery and those pioneers set the template which has tended since to be followed although there have been many exceptions.  Of course, a V8 in a 90^o configuration really should be a “L8” but because the Maybach & Daimler V-twin had established the terminological model, regardless of the angle, such things have always been “V-something”.  

Ferrparts schematic of crankcase parts for the 365 GT4 BB's 4.4 litre (270 cubic inch) flat-12.  According to engineers, this is a "flattened vee".

That’s fine because, conceptually, there’s always a vertex but according to Ferrari, the “Flat 12” engine fitted the various iterations of the Berlinetta Boxer (1973-1974) was also a type of “vee”, despite the two banks of six being horizontally opposed (ie at 180^o); they called it a “flattened vee” which, as Euclid would have told them, there being no vertex, that means they’re describing a “straight-line segment”.  The engineers would have acknowledged the wisdom of the geometers but argued the use was an established convention in engineering to distinguish the two types of “flat” engines (those with pistons which move in and out simultaneously (on the model of a boxer’s gloves) being “boxers” and those in which the pistons move in unison being “flattened vees” or “180^o vees”.  The Ferrari website explains all this while variously and cheerfully calling the engine a “flat 12”, “boxer-type” or “180^o V12”; so, take your pick.  It’s on that site the factory acknowledged the true story about how the original 365 GT4 BB (1973) picked up the “BB” designation and why “Berlinetta Boxer” was concocted as a cover story.

1930 Cadillac V16 452.

At one end of the spectrum, Lancia produced a range of what they described as “narrow-angle” small-displacement V4s and that was apt because the vee was set at 12.5^o, the compactness of the jewel-like power-plant permitting outstanding packaging efficiency.  Less obviously efficient was Cadillac which, for a brief, shining moment, made a 452 cubic inch (7.4 litre) V16 with the two banks eight arrayed in a 45^o vee; that made it a photogenic piece of machinery but it had the misfortune of being introduced in 1930, right at the onset of the Great Depression and although an encouraging 2,500 left the line in the first year of production, demand collapsed and it was only for reasons of prestige GM (General Motors) kept it in the catalogue.  By the time it was withdrawn from sale in 1938, not even a further 1400 had been ordered.  It was in that year replaced by a technically less intriguing 431 cubic inch (7.1 litre) V16 which, built with a 135^o vee, was even less successful, a reported 516 engines leaving the plant although it’s believed only 499 were installed in rolling chassis.  Also with a  vee was the most charismatic V16 of all, the BRM V16 (1947-1955) which was one of those “glorious failures” at which the British are so adept but no grand prix car since has sounded so good.

The DB 60X series was literally “an upside-down V12” but it was regarded thus only because the convention had been to mount them in the still familiar aspect.  Equipped with a dry-sump and direct fuel-injection, the angle assumed in flight made little difference to the engine, unlike the early Allied aero-engines which were carburetor-fed.  In combat, that was a great advantage for the German pilots who were fortunate the British didn't accept a spy's offer to supply them with a stolen example of the vital DB fuel pump.  As it was, the RAF (Royal Air Force) had to wait until Bendex developed a "pressurized carburetor" (a type of throttle-body fuel-injection) although the stop-gap "fix" which proved a remarkably effective partial amelioration was "Miss Shilling's orifice".   

In the first half of the twentieth century, the V12 engine held great appeal for the designers of military aircraft because the layout solved several critical aerodynamic and mechanical problems which would have remained insurmountable (and probably exacerbated) had the traditional in-line engines been further extended or enlargedused.  More cylinders meant more power and this the V12s achieved without the excessive length (and thus the dreaded “crankshaft flex”) which would have been suffered by an in-line 12.  The virtues the designers sought were (1) robustness, (2) lightness, (3) power and (4) compactness, the quest always for a better power-to-weight ratio and for this the V12 proved the “sweet-spot”.  The British industry in the inter-war years developed many V12 aero-engines (notably the Rolls-Royce Merlin which became famous by powering all the early Supermarine Spitfires) but because the Germans didn’t return to military aviation until the mid-1930s, they had the advantage of working on a “clean sheet of paper”, one of their many innovations being the “inverted V12”, the most numerous the Daimler-Benz DB 600 series.  In these, the crankshaft was above the cylinders so the cylinder banks pointed downward and this offered several advantages including (1) improved pilot visibility, (2) greater propeller ground clearance (meaning also the larger propellers became possible without needing longer landing gear), (3) easier access to accessories (fuel pumps, magnetos and such at atop, meaning mechanics could fix or replace components more quickly), (4) the fitting of a Motorkanone (a cannon firing through the propeller hub) became viable (5) shorter exhaust stacks and (5) the plumbing for the advanced MFI (mechanical fuel injection) system was both simplified and made more accessible.

Exhaust stubs of left-hand bank of a BRM V16.

Like the DB inverted V12s, some of the BRM V16 had low-mounted exhaust stubs but whether the flow of the gasses had any effect on aerodynamics was never studied although, the breathing must have been efficient because the 1.5 litre (91 cubic inch) V16 could at 12,000 rpm generate up to 600 HP.  At full cry it produced the most glorious sound ever heard in Formula One but unfortunately it was at the threshold of pain for those standing close so the system was revised to use a pair of long "dump pipes".

Almost as a footnote, the German designers noted they were able also to exploit the location of the stubs to gain unanticipated benefits from the path of the inverted V12’s exhaust thrust and cowling flow.  It’s overstating things to call it a “jet thrust” effect but that’s how it can be visualized, high-velocity exhaust gases exiting the stacks producing a small rearward thrust component and the engineers experimented to find the optimum length and angle, calculating the “effective thrust” at between 50–150 lb (220–670 N) depending on the power setting and throttle used.  In real-world conditions, this translated into perhaps an additional 25-odd horsepower which may not sound significant in engines generating over a thousand but in combat, it could be the difference between life and death.  Additionally, the aeronautical engineers used an aspect of fluid dynamics to improve the “boundary-layer management” along the cowling (ie using the hot, high-energy exhaust stream flowing along the sides of the cowling to “energize” the boundary layer of air "attached" to the fuselage surface).  What this did was slightly delay any flow separation, reducing “draw” and providing a better flow over the wing’s critical root area.  The differences were slight and subtle but again, in combat happening at altitude, at hundred of mph, inches and seconds matter so it could be the difference between life and death.

1350–1400: From the Middle English knobe & knobbe, thought almost certainly from a Scandinavian or German source and probably at least influenced by the Middle Low German knubbe & knobbe (knob; knot in wood; bud), the Middle Dutch knobbe & cnoppe, the Dutch knop (knob, button, bud), the Old Frisian knopp & knapp, the Old High German knopf (bud, pommel of a sword, knot, loop), the Middle High German knospe, the German Knopf (button, knob) & Knospe (bud), the Danish knap (button) & knop (knob, button, bud) and the Old Norse knyfill (short horn).  Most etymologists seem most convinced by it being a variant of the Proto-Germanic knappô (knob, lump) & knuppô (lump, clod), both among the “kn-” words related to knudaną (to knead).  Probably related were the Middle English knap & knappe (small projection, knob (in the sense of “button, tassel, tuft etc”), hill, hilltop etc)), from the Old English cnæp & cnæpp (summit, top), which may in some way be linked with the Old Norse knappr (small projection, knob (in the sense of “button, head of a stick etc”)) (and from which English gained knop), the source again the Proto-Germanic knappô.  The meaning “knoll, isolated round hill” seems first to have appeared in the 1640s and, perhaps surprisingly, no instance of “doorknob” has been found prior to 1829 although the word may have been long in oral use (drawer-knob, window-knob etc all followed).  Knob is a noun & verb, knobless is a noun, knobbed & knobbing are verbs, knoblike & knobby are adjectives; the noun plural is knobs.

Yorkeys Knob, Cairns, Queensland, Australia.

In idiomatic use, the phrase “same to you with knobs (sometimes “brass knobs”) means “the same to you but even more so” (used typically in response to an insult or slight).  A “knob-twiddler” can be an informal term for a technician or console operator whose job entails adjusting electronic devices via knobs but it can also describe anyone whose role seems either unimportant or not particularly demanding.  As machinery and later electronics became an increasingly ubiquitous part of life, so did knobs and as early as the late nineteenth century the humorous “knobologist” had been coined to describe both those designing the system and the “knob-twiddlers” using them; the discipline of design was of course dubbed “knobology” and that remains a core component of ergonomics, exploring imperatives such as placement, size, tactility and labelling, all of which influence the functionality of controls on an instrument as relevant to their application.  The knobologists deeply were implicated in convenient physical switches, knobs and buttons disappearing from cars and re-imagined virtualizations on inconvenient touch-screens.  Such has been the reaction (including the realization the change made driving more accident prone) that the tactile controls are making a welcome comeback.  The now archaic “knob-thatcher” was an affectionate term for a maker of wigs while the more modern “surfer's knob” was slang from the sport, describing a hard bump or nodule on a surfer's knee, shin or ankle, resulting from recurrent contact with their surfboard.  In engineering and metallurgy, “to knobble” was (1) to render a surface with a knobbly finish and (2) to produce wrought iron by treating semi-refined puddled iron on a hearth before shingling, a specialized device in the business being the ominous sounding “knobbling furnace”.

Gay men supporting lesbians at the first “Dyke March”, Washington DC, April 1993.  The sign held by the protester at the far left uses the compound word for which the euphemisms “knob polisher” & “knob-gobbler” were coined.

Because knob was popular slang for penis, a number of derived terms predictably emerged.  A “knob polisher” or “knob-gobbler” was “one who gives fellatio”.  “Knob rot” was a reference to certain sexually transmitted diseases contracted by men, the acute condition “galloping knob rot” describing a rapidly progressing or uncontrollable variant of the condition.  A “knob job” was the act of fellatio.  “Knob cheese” (the terms “cock cheese”, “dick cheese” and (in context) even “cheese”) was vulgar slang for smegma (a whitish sebaceous secretion that collects between the glans penis and foreskin or in the vulva).  “Knob jockey” must however be used with care because it has variously been applied to (1) gay men, (2) promiscuous straight women and (3) promiscuous straight men; context thus matters.

Interior of Porsche 917K with cool (in both senses of the word) balsa-wood shift knob.  The obviously "fake" passenger bucket seat was installed to comply with the rules in sports car racing.

To this day, the myth persists the balsa-wood gear-shift knob used in the Porsche 917 was there as a “weight-saving measure”.  While it’s true the small knob was light, the difference between it and the aluminum or magnesium units the company had fitted to earlier race cars would have been so insignificant it’s doubtful it would have equalled a gulp of coffee the driver may or may not have enjoyed.  The stylish timber piece was however not a decorative flourish but a legitimate engineering solution to ameliorate one manifestation of “chronic heat soak”.  In 1969, the 917 was a radical advance which, Dreadnought-like, rendered all other cars in its class instantly obsolescent but the flat-12 engine (Porsche’s first in the configuration) radiated so much heat it was difficult to manage.  In a tradition it would not for decades abandon, Porsche continued to use air-cooling for the engine (which really means “oil cooled” about as much) and it ran hot; between that heat source and the gear level was a unbroken metal path, each component a most efficient conductor.  During endurance racing (some events conducted over 24 hours), cockpit temperatures could reach what doctors would rate as “extreme”.  The metal lever was just one of the sources of this heat and the knob (which sat next to the driver’s knee) needed to be grasped by the driver, often many times a minute; were it to become so hot it caused pain, it would have been safety issue.  Although in 1969 the space-age was at its zenith, the materials which could have made a driver’s gloves close to heat-proof were not then commercially available so they gained much of their protective quality from thickness but the problem was they could be only so thick because a driver needed still to handle a highly-geared steering wheel and operate the many knobs and switches within arm’s reach.  Balsa-wood, with its very low thermal conductivity was ideal because while not exactly cool to the touch after a few hours on the track, it never got so hot it felt unpleasant.  It also had adequate strength for its task; a gear-lever knob does not bear structural loads and, being Porsche, it received the same careful attention as every other component, each one precisely machined to exact dimensions before receiving two coats of clear lacquer.  Most variants of the 917 used the Balsa-wood part although when (as the “Turbo-panzers”) the most powerful of the breed appeared in the Can-Am (for Group 7, unlimited displacement sports cars) a metal knob was fitted, made possible because Group 7 was for open cars and significantly that reduced cabin temperatures.  By the late 1970s when the space age had made available materials (phenolic plastics, composites etc) with superior insulation qualities, the need to resort to a balsa-wood knob vanished but the visual appeal remained and in the aftermarket, 917-style knobs remain widely available.

1959 Ford Fairlane Galaxie 500 Sunliner with suicide knob (on steering wheel at 10 o'clock).

“Suicide knob” was the most popular name for the device attached to a vehicle’s steering wheel which facilitated easier “single arm steering”.  The idea dated from the days before the almost universal fitting of power-steering and the things became popular in the US in the US in the 1950s and 1960s as even low-priced cars became heavier; for some drivers, they were invaluable when manoeuvring at low speed, especially when reversing.  They were known also as the “necker knob”, “wheel spinner” and “granny knob” but the most correct term was “Brodie Knob”, the name in honor of Steve Brodie (1861–1901), an apparently rather raffish gentleman from New York City who, as a last resort in 1886 after losing everything gambling, staged a stunt in which he jumped off the Brooklyn Bridge (site of a good many suicides), the lure a sum of money he was bet although the details of that are murky.  Mr Brodie anyway survived to collect on the wager and, on the basis of the notoriety gained, began performing other dare-devil acts for even more money.  So the jump from the Brooklyn Bridge was a good career move although the consensus now is it was a cunning stunt (ie a scam), a weighted dummy the real diver with Mr Brodie entering the water from the safety of the shoreline.  In fairness, at least some of his subsequent dangerous stunts were verified by observation and he parlayed his fame into a successful career in business, becoming a noted philanthropist and dying a rich man.

The invention of the suicide knob generally is credited to Joel Thorp of Wisconsin but similar devices had for centuries been in use on land and water.  What Mr Thorpe described in the supporting documents for what was issued as US Patent 2,101,519 STEERING WHEEL SPINNER KNOB (Dec 7, 1937) was an “improvement” of the concept:

“The present invention relates generally to improvements in appliances for facilitating manipulation of the steering wheels of vehicles, and relates more specifically to improvements in the construction and operation of spinner knob attachments co-operable with the peripheral rims of steering wheels or the like in order to effect more convenient and rapid operation of such wheels under certain conditions of use.  Generally defined, an object of my present invention is to provide an improved steering wheel spinner knob which is simple in construction and highly efficient in use.”

A young lady wrapping practiced fingers around the timber shift knob in 1970 Maserati Indy (Tipo 116, 1969-1975).  In the era, it was fashionable in Italian exotica for the knob and steering wheel rim to match (ie in leather or wood).

Although widely used on tractors, heavy transport vehicles and such, it was in the 1950s as cars in the US became heavier the suicide knobs gained popularity and some of that was due to reasons Mr Thorp probably never envisaged.  One receptive market was males aged 17-25 (a crew infamous for many reasons) who found the combination of suicide knob and bench seat made an idea ecosystem, enabling one hand to be used steer the vehicle while the "free" arm could wrap around the girlfriend (or alternative) who affectionately was resting her head on the driver’s shoulder.  In this arrangement, a driver’s attention more easily could be divided between her and the road.  It was also males aged 17-25 who were the core of the hot-rod community which began as a West Coast phenomenon (induced by a critical mass of the right demographic, available disposable income and a good supply of cheap, used cars which easily could be modified as desired) and they found suicide knobs the best way to “do a half donut” (a spin of one’s hot rod through 180^o), the trick being to grip the knob and then suddenly turn the wheel while applying full throttle, resulting in a loud, spectacular maneuver, made the more pleasing for the driver by him having “left his mark” in strips of runner on the road.  This, the hot rodders called “spinning a brodie”, a variant on the earlier “doing a Brodie” (a dangerous or otherwise inadvisable act) which entered the language after the nation-wide publicity which followed Mr Brodie’s alleged leap from the Brooklyn Bridge.  In the era, a Brodie Knob was as essential a piece of equipment as one’s packet of unfiltered Camel cigarettes or pair of fluffy dice hanging from the rear-view mirror.

1962 Maserati 3500 GTi.  Some Maserati 3500 GTs (Tipo 101, 1957-1964) had the unusual feature of having front and rear quarter-vents fitted to the same door; they were opened and closed using knurled, stainless steel knobs.

The dark appellation “suicide knob” was bestowed because (1) the devices came to be associated with accident-prone drivers (the “males aged 17-25” cohort prominent in the statistics) who probably did use the things to engage in “risk-taking” and (2) by virtue of their location (by default affixed to the upper quadrant) on the wheel, they were a genuine danger in accidents and, in an era of non-collapsible steering columns, tales of them penetrating the eye socket, causing irreparable loss of vision and traumatic brain injury, were legion.  The crusading US lawyer Ralph Nadar (b 1934) is criticized for much but the contribution his book Unsafe at Any Speed (1965) made to reducing the death toll on the roads cannot be under-estimated and the effect was world-wide because the rest the industry eventually followed the lead of the US legislation which came in the book’s wake.  In the US and elsewhere, change was of course resisted but it came and while it’s not possible to estimate how many deaths and often gruesome injuries the reforms prevented, no one denies it’s a big number.  The suicide knob was one minor casualty of the movement and in road-registered vehicles, in most jurisdictions (although some US states remain permissive), such devices are permitted only for specialized (often low-speed) vehicles and if used by drivers with some disability which precludes the use of conventional controls.

Another to make a life-saving contribution to reducing the road told was George Hurst (1927-1986; founder of his eponymous company) whose great legacy to humanity was the “Jaws of Life”, a hydraulic cutter he first developed in 1961 after being shocked at how long it sometimes took to extract the driver from the crumpled wreck of a race car.  The great advantage of the “Jaws of Life” was that it worked like a very powerful pair of scissors, avoiding the showers of sparks produced by mechanical saws, always a risk to use in areas where fuel is likely to have been spilled.  The basic design came to be used in hydraulic rescue devices worldwide and quite how many lives have been saved by virtue of its use isn’t known but again, it would be a big number.

Two decades of progress: Shifter for the two-speed Powerglide automatic transmission in 1953 Chevrolet Corvette (left) and a classic spherical shift knob in 1972 Chevrolet Corvette LT1.  The delicate-looking shifter in the 1953 Corvette seems modest but the location was a world-first for an automatic and was efficient because the location (between the driver’s seat and transmission tunnel) provided the shortest possible path to the linkage.  As late as 1964, Chrysler used a similar apparatus in the 1964 300K.

However, before the Jaws of Life, Hurst was already famous in the vibrant sub-culture which was at the times also known for its propensity to purchase and install suicide knobs.  Hurst produced “shifters” which were the assemblies connected to a transmission, used by the driver to “change gears” and they proved instantly popular which may seem strange given every manufacturer at the time included a shifter with every vehicle.  However, beginning in the late 1930s, the US manufacturers had begun moving from centrally located, floor-mounted levers to units on the steering column because it made for better packaging efficiency in the cabins, then optimized for bench-seats with three-astride seating.  That move achieved the goal but with the linkage between lever and gear-changing mechanism now longer and making more turns, some precision in the shifting was lost and column shifting (the once almost universal “three on the tree”) was less conducive to an enthusiastic driving style (such as that of the “suicide knob equipped” crowd).  It was in the 1950s the taste for floor-shifts like those in European sports cars began to gain critical mass and even though the 1953 Chevrolet Corvette was hardly a sports car in the tradition of MGs, Fiats and such, it’s notable Chevrolet from the start installed a floor shift for the (two-speed!) Powerglide automatic transmission; it may not have been a sports car with a “four-on-the-floor” but it had a floor-shift so there was that.  Automatic transmissions in mass-produced cars was then something of a novelty barely a decade old and the Corvette’s floor shift was apparently a world-first.

A butter curler producing curls.  Generally, the curlers come in large and small, respectively producing a curl notionally equivalent to a dollop or a knob (half-dollop).  In the kitchen however, knobs and dollops are what the chef decides they are.

Four-speed manual transmissions began to appear in Detroit-made cars in the late 1950s and within half a decade George Hurst’s shifters were close to obligatory for any racer (authorized or not) seeking “street cred” and it wasn’t a confected image, the Hurst shifters demonstratively superior without being excessively expensive.  So stellar did their reputation become even GM (General Motors) relaxed their long-standing ban on other brand-names being associated with their products and made a feature of one being standard equipment of the 1964 Pontiac GTO, the car credited with being “the first muscle car” and such was the success in 1965 the shifter’s handle was even permitted to be embossed: HURST.  Soon, other manufacturers actively were seeking co-productions.  George Hurst’s path to market domination was shockingly simple and might have come from a textbook: (1) a perfected design, (2) skilful engineering in development, (3) high quality in production and (4) an attractive price, a combination of elements with great appeal for buyers and manufacturers alike.

Hurst’s dual-gate automatic transmission “His and Hers” shifter with conventional apparatus “for the automatic minded little lady” and a performance-oriented configuration offering manual control for the “man who really wanted a 4-speed standard stick but bought this extra just for her.”  Note the unfamiliar shift pattern, the now universal PRNDL not an industry standard until 1965, the year before it was demanded by regulations.  From the early days of automatic transmissions in the 1940s, reverse had been directly adjacent to Low, allowing drivers more easily to emulate what was done with manual transmissions when a “rocking” was being induced to try to free a vehicle from mud or snow.  It was a quirk of the age and, because reliability was not then what decades later came to be expected, the early transmissions included a second (rear) fluid pump to permit push/tow/hill starts.  Probably, not many much dwelt on the shape of the knob Hurst put atop the His and Hers” shifter but in geometry it would be described as an oblate spheroid with two parallel planar truncations.  Now easily modelled in software rendered with a 3D printer, perfecting a shape like this for production used to absorb much time on the drawing board and in the creation of prototypes.  A spheroid is an ellipsoid generated by rotating an ellipse about one of its principal axes which, if “stretched” along one axis becomes a prolate spheroid (ie elongated and something like a rugby ball).  If slightly flattened along the axis of rotation, it’s an oblate spheroid (like planet Earth which isn’t quite a pure sphere) but the His & Hers knob, having a slight elongation along the shifter’s axis, is closest to a prolate spheroid.  The planar-truncation (ie sliced by two parallel planes) created the (left & right) flat faces and the knob can thus be described as a “truncated ellipsoid” or “truncated prolate spheroid” but anyone wishing to out-nerd the rest would probably coin something like “biaxial ellipsoid with parallel planar truncations”.

It was early in the era of second-wave feminism (1960s-1980s) that George Hurst made his brief foray into marriage guidance counselling.  First-wave feminism (1895-1950s) is sometimes called the “de jure” or “structural” period because the focus was on legal issues such as women's suffrage, property rights and political candidacy but, in the West, an early victory was overcoming any opposition to women being granted driver’s licences.  Attitudes however evolved not wholly in parallel with legal rights and even today, among some, the view persists it’s men who are focused on performance and speed while women value vehicles using other criteria.  Impressionistically, that stereotype is not wholly without foundation but, since second wave feminism reset the rules, it’s no longer possible to run advertising perpetuating the notion.  The “His and Hers” shifter worked with a key-lock which enabled the husband to ensure only he could use the “manual override” feature and the idea in recent decades has been revived although this time the target of the lockout includes one’s (presumably male) children and any concierge or attendant who might be entrusted with parking one’s car.

The magic of Hurst’s shifters was in the mechanism but, just as for computer users the mouse and keyboard assume great importance because it’s by touching these relatively simple pieces of hardware that use can be made of the machine’s more sophisticated internals, it was the shifter’s knob which was a driver’s most intimate connection with the transmission.  Although in the art deco era there had been some lovely detailing, it wasn’t until the 1960s most conceptually moved beyond beyond “variations on a theme of sphere” and Hurst was among the manufacturers to explore shapes and substances.  There were “T-Handles” (which, usually as "T-Bars", were for decades popular around the world for automatics) and “Horseshoes” which attracted admiring glances but didn’t catch on and any number of novelty items including billiard balls (the “8 ball” predictably a favourite of the V8 crowd) and scale models of this and that including human body parts such as the skull and mammary gland.  Knobs could be of plastic, wood or various metals and came in designer colors, velvet coatings a nice touch of the 1960s.  The most fetishized of the muscle car era however was Hurst’s “Pistol Grip Shifter” which did what it said on the tin: it gave the user the feeling of holding a handgun.  In the 1960s, gun culture in the US hadn’t yet become what it is today (as now defined, the first “mass-shooting” didn’t happen until 1966) but it was still a place with a lot of firearms.  However, despite the potential implications, when in 1970 Chrysler made one standard equipment on the 1970 Plymouth ‘Cuda, one brochure made mention of the device only with the bland: “...a convenient pistol grip”.  For a corporation which called the Cuda’s hood scoop the I.Q.E.C.A.G. (Incredible Quivering Exposed Cold Air Grabber), it seemed a missed opportunity though it didn’t have much linguistic luck with I.Q.E.C.A.G., customers and everybody else deciding it was a “shaker”.

Architecturally, the choice between specifying door levers or door knobs is often one of mere preference or aesthetic conformity but for public or commercial buildings, some regulatory authorities now mandate the use of levers because typically they are easier to use for those with disabilities (especially if hand-mobility is limited) as they demand less dexterity.  Additionally, being circular and often highly polished, knobs can be hard to use with wet hands so that’s a consideration in kitchens, bathrooms and such; nor do young children find them as convenient as a handle.  So, all that would seem to make a compelling case for the handle but for domestic use, there’s one quirky consideration some may wish to include when making the choice.  While there are verified cases of cats and dogs learning to open doors using a handle, no pet has yet been observed mastering the turning of a door knob; while a rare problem, the chance of one’s cat or dog opening door using a lever is not zero and, because houses tend to use the same style of lever throughout, once they have learned to open one door, they’ve really learned to open all.  If it’s a concern, the good news is most doors are adaptable for either so replacing a lever with a knob does not usually require the door being replaced.
