Slant

Slant (pronounced slant or slahnt)

(1) A surface, structure, line etc at a slope or in an oblique direction.

(2) In (US) football, an offensive play in which the ball-carrier runs toward the line of scrimmage at an angle (known also as the “slant-in”, a pass pattern in which a receiver cuts diagonally across the middle of the field).

(3) In prosody, as “slant rhyme”, a synonym for the “half rhyme”, “near rhyme” & “quasi-rhyme” (a form of imperfect rhyme in which the final (coda) consonants of stressed syllables (and, in modern English poetry, any following syllables to the end of the words) are identical in sound, but the vowels of the stressed syllables are not.

(4) In typography, a synonym of slash ( / ⟩, particularly in its use to set off pronunciations from other text (not used in IT where the distinctions are between the forward-slash (/) and the back-slash (\) which nerds call respectively the slash and the slosh.

(5) In biology, a sloping surface in a culture medium.

(6) In hydro-carbon extraction, as “slant drilling”, a technique in which the drilling is undertaken at an oblique angle rather than the traditional vertical orientation.

(7) In extractive mining, as type of run in which a heading is driven diagonally between the dip and strike of a coal seam.

(8) In informal use, a glance or look.

(9) To veer or angle away from a given level or line, especially from a horizontal; slope (in to incline, to lean).

(10) Figuratively, to have or be influenced by a subjective point of view, bias, personal feeling or inclination etc (often as “slant towards”, “slanted view” etc); a mental leaning, bias, or distortion (“feminist slant”, “MAGA slant”, “liberal slant”, “business slant” et al).

(11) To cause to slope.

(12) Figuratively, to distort information by rendering it unfaithfully or incompletely, especially in order to reflect a particular viewpoint (more generously sometimes described as “spin” or “massaged”).  The concept is known also as “angle journalism” (the particular mood or vein in which something is written, edited, or published).  In Scots English, the meaning “to lie or exaggerate” captures the flavor.  When used to describe the composing, editing, or publishing of something to attract the interest of a specific sub-group (a “slanted” story), “slanted towards” is necessarily pejorative if used only to suggest something optimized to appeal to a certain market segment or demographic (ie it’s more like “aimed at” or “intended for”).

(13) In slang, as “slant eye” (a racial slur now listed as disparaging & offensive), a reference to people from the Far East (applied historically mostly to the Chinese & Japanese), based on the shape of the eyes.  The variants included “slit eye”, “slitty-eyed” & “slopehead”, all equally offensive and now proscribed.

(14) In painting (art) a pan with a sloped bottom used for holding paintbrushes; a depression on a palette with a sloping bottom for holding and mixing watercolors; a palette or similar container with slants or sloping depressions.

(15) In US regional slang, a sarcastic remark; shade, an indirect mocking insult (archaic).

(16) In US slang, an opportunity, particularly to go somewhere (now rare).

(17) In historic Australian colonial slang, a crime committed for the purpose of being apprehended and transported to a major settlement.

Circa 1480s: From the Middle English –slonte or -slonte, both aphetic (in phonetics, linguistics & prosody, “of, relating to, or formed by aphesis” (the loss of the initial unstressed vowel of a word)) variants of aslant, thought to be of Scandinavian origin.  The other influence was probably the earlier dialectical slent, from the Old Norse or another North Germanic source and cognate with the Old Norse slent, the Swedish slinta (to slip) and the Norwegian slenta (to fall on the side), from the Proto-Germanic slintaną (which, in turn, was probably in some way linked with aslant.  Slant & slanting are nouns, verbs & adjectives, slanted is a verb & adjective, slantish is an adjective, slantwise is an adjective & adverb and slantingly & slantly are adverbs; the noun plural is slants.  The pleasing adjective slantendicular is listed by some as non-standard and presumably is proscribed in geometry and mathematics because it's an oxymoron; it’s a portmanteau word, the construct being slant + (perp)endicular.  It may be useful however in commerce or engineering where it might be used to describe something like a tool with a shaft which at some point assumes an oblique or skewed angle.   So it’s there to be used and slantindicular should be applied to stuff which is neither wholly nor fully slanted and in architecture, such structures are numerous.  In commerce, it could be used as a noun.

The noun slant by the 1650s was used to mean “an oblique direction or plane” and began in geography & civil engineering (of landforms, notably ski-slopes), developed from the verb or its adjective.  The now familiar (in the Fox News sense) meaning “way of regarding something, a mental bias” dates from 1905 while the derogatory slang sense of “a person of Asian appearance” came into use some time in the 1940s, a direct descendent from the earlier "slant-eyes", documented since 1929.  The verb slant is documented since the 1520s in the sense of “obliquely to strike (against something)”, an alteration the late thirteenth century slenten (slip sideways), the origin of which is murky but etymologists have concluded it came (via a Scandinavian source (noting the Swedish slinta (to slip)) and the Norwegian slenta (to fall on one side), from the Proto-Germanic slintanan.  The intransitive sense of “to slope, to lie obliquely” was in use by the 1690s, while the transitive sense of “to give a sloping direction to” had emerged by the early nineteenth century.  As early as the late fifteenth century forms were in use as an adverb, the adjectival use attested from the 1610s.  The technical use in literary theory as “poetic slant rhyme” was first used in the mid 1920s (assonance or consonance) although such lines had appeared for centuries, used sometimes deliberately as a device, sometimes not.  In the following stanza by English poet Peter Redgrove (The Archaeologist, published in Dr Faust's Sea-Spiral Spirit (1972)), the second and third lines contain a form of slant rhyme while the first and fourth have pure rhymes:

So I take one of those thin plates
And fit it to a knuckled other,
Carefully, for it trembles on the edge of powder,
Restore the jaw and find the fangs their mates.

You are watching Fox.

While it’s unlikely volumes of the poetry of Emily Dickinson (1830–1886) sit upon the bookshelves of those members of the Fox News audience who have bookshelves, they likely would concur with her words: “Tell the truth but tell it slant.”  “Slanted reporting” has become something which in recent years has attracted much attention (and much hand-wringing by the usual suspects) as an increasingly polarization of positions has been alleged to be a feature of political discourse in the West.  There is little doubt the effect (as reported) is obvious but there’s some debate about both the mechanics and the implications of the phenomenon.  As long ago as 2018, a study found that although the tenor and volume of things on X (formerly known as Twitter) was found to be increasingly toxic and surging, the number of active users engaged in these political polemics was found to be tiny and their effect was distorted by (1) the huge number of tweets they tended to post, (2) the propensity of their fellow-travelers to re-tweet and (3) the use of bots which were more prolific still.  If anything, recent voting patterns suggest it would seem the views of the general population appear to be trending away from the extremes towards the more centralist positions offered by independents or small-parties, something most obvious in Australia where compulsory voting exists.  Outfits like Fox News offer a slanted take on just about everything (and promote country & western music which truly is inexcusable) but this is something which has been identifiable in the news media as long as it’s existed and their blatant bias is hardly subversive or threatening, simply because it is so blatant.  What was most interesting in what emerged from the recent defamation suit filed by Dominion Voting Systems against Fox News suggested the network’s stance on things was motivated more by the financial imperative than ideological purity.  Intriguingly, what some analysts concluded was that if the universe shifted and the Fox News audience transformed into a bunch of seed-eating hippies, there would follow Fox’s editorial position, the slant being towards the advertising revenue rather than a particular world view.  Of course, there are some slants which are unalterable and dictated by ideological purity but with commercial media, it’s likely sometimes cause is confused with effect.

The Leaning Tower of Pisa (left) and Lindsay Lohan in The Parent Trap (1998) in front of London’s perpendicular Big Ben (1859) (right).  The architect’s original name for the latter was a typically succinct “Clock Tower”, chosen because it housed the “Great Bell of the Great Clock of Westminster” but it was in 2012 renamed “Elizabeth Tower”, marking the Diamond Jubilee of Elizabeth II (1926-2022; Queen of the UK and other places, 1952-2022), something little noted by Londoners or those beyond who continue to prefer the nickname “Big Ben” although strictly speaking that’s a reference only to the “Great Bell” a 13.5 ton (13.7 tonne) casting in bell metal (a bronze which is an alloy of about 77% copper & 23% tin).  The origin of the nickname is contested but there are no romantic tales, all the possible inspirations being worthy white men as was the Victorian way.

Although in Italy alone there are seven leaning towers (three of which stand (ie lean) in Venice), it’s the torre di Pisa (Tower of Pisa) which is by far the best-known and a frequent Instagram prop.  Built between 1173-1372, the structure in the Piazza del Duomo (Pisa’s Cathedral Square) is the campanile (the freestanding bell tower) of the adjacent Pisa Cathedral and the famous lean of some 4^o (actually somewhat less than its greatest extent after more than a century of compensating engineering works) was apparent even during construction, the cause the softness of the sub-surface.  That geological feature has however contributed to the tower’s survival, the “rubber-like” sponginess below acting to absorb movement and despite a number of severe earthquakes in the region over the centuries, the tower remains.  It is of course known as the leaning tower than a sloping, oblique or slanted tower, probably because of the conventions of use which evolved in English.

The words “sloping”, “oblique”, “slanted”, & “leaning” all describe something not vertical or horizontal there tend to be nuances which dictate the choice of which to use.  Sloping generally is used of something which inclines or declines at a gentle or continuous angle, the implication being of a gradual or smooth transition from elevation to another, such as the way a hillside rises gradually rises to its summit.  Oblique is mostly a matter of specific angles and is thus common is mathematics, geometry and engineering.  Again, it’s a reference to something neither parallel nor perpendicular to a baseline but it tends to be restricted to something which can be defined with an exact measurement; in geometric or technical use, an oblique line or angle is one neither 90^o nor perfectly horizontal.  Slanted describes something positioned at a diagonal, often used to imply a more noticeable or sharp angle but also is widely used figuratively, metaphorically and in idiomatic phrases.  Leaning refers to something tilted or positioned at an angle due to external pressure, the object in an unstable position and in need of support.  The implication carried is that something which “slants” is designed thus to do while something which “leans” does so because of some design flaw or unexpected external force being applied so it’s the leaning and not the sloping tower of Pisa, even though the structure has assumed quite a slope.

Slanting Engines

On a slant: Diagram of the mounting of the M194 straight-six engine in the Le Mans winning Mercedes-Benz 300 SL (W194) canted at a 40^o slant (left); the Mercedes-Benz M196 straight-eight engine schematic (centre) and installed in a 1954 W196R "Streamliner" at a 53^o slant (right).  The two large donut-like objects at the front are the inboard, finned brake drums; at the time, the engineers maintained disk brakes were "not yet ready for use". 

There are “slant” engines and they exist in three configurations.  The first is simply a conventional in-line engine (straight-six, straight-eight etc) which, when installed in a vehicle, is fitted with the block canted to the left or right, the objective being a lower hood line which means a better aerodynamic outcome.  A classic example was the Mercedes-Benz W196R Formula One racing car (1954-1955) in which the straight-eight was canted to the right at a 53^o angle, the technique carried over when the same structure was used to produce the W196S (1955) used to contest the World Sports Car Championship.  Rather opportunistically, the W196S was dubbed the 300 SLR (one of which in 2022 became the world's most expensive used car, selling at a private auction for US$142 million) as a form of cross promotion with the 300 SL (W198, 1954-1956) Gullwing then in production, even though the two types shared little more than nuts, bolts and a resemblance.  The 300 SL did however also have its straight-six engine sitting at a slant, this time canted at a 50^o angle and although the factory never published an estimate of the reduction in drag, it’s long been presumed to be “at least several percent”.  Another advantage of the configuration was it made possible the use of “long-tube” runners for the induction system, taking advantage of the properties of fluid dynamics to permit them to be tuned either for mid-range torque or top-end power.  The concept used math which had been worked out in the nineteenth century and had often been used in competition but it wasn’t until 1959 when Chrysler in the US released their picturesque induction castings that the system, imaginatively named the “Sonoramic”, reached a wider audience.

Chrysler Slant Six (170 cid, 1963) schematic.

The “true” slant engines were those with a slanted block atop an otherwise conventional arrangement of components, the best known of which was Chrysler’s long-serving “Slant Six”, produced in displacements of 170 cubic inch (2.8 litre, 1959-1969), 198 cubic inch (3.2 litre, 1970-1974) and 225 cubic inch (3.7 litre, 1960-2000).  The block of the Slant Six was canted to the right at a 30^o and like Mercedes-Benz, Chrysler took advantage of the space created to the left to produce some wide induction runners, the most extravagant those used by the special Hyper Pack option package which used a four barrel carburetor, enabling the engine to produce power which made it competitive with many V8 powered machines.  Although the name “Slant Six” became famous, it was only in the mid-sixties it caught on, Plymouth originally calling the thing a 30-D (a reference to the a 30^o slant), hardly very catchy and something to which only engineers would relate and Slant Six was soon preferred although the aficionados really like “tower of power” and the engine even today still has a devoted following.

Chrysler didn’t restrict the Sonoramics to the big-block V8s, using it also on the short-lived (1960-1962) Hyper Pak performance option for the both 170 cubic inch (2.8 litre, 1959-1969) and 225 cubic inch (3.7 litre, 1987-2000) versions of the Slant Six, the engineers taking advantage of the space afforded by the canted block to permit the curvaceous intake runners nearly to fill the engine bay.  The Hyper Pak wasn't seen in showrooms but was available as an over-the-counter kit (literally a cardboard box containing all necessary parts) from Dodge & Plymouth spare parts departments and its life was limited because it became a victim of its own success.  Although less suitable for street use because it turned the mild-mannered straight-six into something at its best at full throttle, in the race events for which it was eligible it proved unbeatable, dominating the competition for two years, compelling the sanctioning body cancel the series.

Manifold porn: The Slant Six's angle meant there was much space available to the left and a range of intake manifolds followed, some of which remain available to this day.  Using variations of the sonoramic tuning, manifolds were produced for single, two & four barrel carburetors and between 1965-1968, Chrysler's Argentine operation produced the Slant Six in a version with twin single barrel carburetors.  The use of the properties of fluid dynamics to gain power or torque as desired quickly was adopted by the industry as an engineering orthodoxy.

Some myths seem to have become attached to the Hyper-Pak.  What seems to be true is the original kit, sold in 1960 for the 170 engines used in competition, was a genuine homologation exercise and as well as the intake manifold & Carter AFB four barrel carburetor, it included all the internal parts such as the high-compression pistons, the high-lift camshaft and the valve train components needed to support the consequently higher engine speeds.  Because the competition rules allowed modifications to the exhaust system, on the track the cars ran tubular steel headers which fed an open exhaust, terminating in the racers' preferred “dump pipe”.  After the requisite number of “complete” kits were sold, thus fulfilling the homologation demands, the kits were reconfigured and included only the “bolt-on” parts such as the induction system and a camshaft which, while more aggressive than the standard unit, wasn’t as radical as the one used on the track but could be used in conjunction with the standard valve train and Chrysler’s TorqueFlite automatic, thus expanding the Hyper-Pak’s appeal.

At the same time, the availability was extended to the larger 225 which between 1961-1963 was also available with an aluminum block, thus becoming one of the small number of engines configured with the combination of an aluminum block with a cast-iron head.  US manufacturers were at the time aware the trend was for cars to continue getting bigger so they were interested in ways to reduce weight.  However, despite saving some 70 lbs (32 KG), Chrysler’s aluminum block was, like General Motors’ (GM) 215 cubic inch (3.5 litre) V8, short-lived (though the V8 after being sold to Rover enjoyed a long, lucrative and prolific second life, not finally laid to rest until 2006) for not only were teething troubles encountered with the still novel method of construction, the accountants made clear using cast iron was always going to be cheaper so the industry just accepted weight gain and whenever required, increased displacement to compensate, an approach which persisted until the first oil shock of the early 1970s.

1970 Dodge Challenger (1970-1974) with 225 Slant Six.

Until 1973, both the Challenger & the corporation's companion pony car (the Plymouth Barracuda (1964-1974)) was available with the Slant Six (198 & 225) although the fitment rate was under 10%, unlike the early pony cars (Ford Mustang, Chevrolet Camaro and the early Barracudas) where the six-cylinder versions would at times be close to 40% of production.  Many of the surviving Slant Six Challengers & Barracudas have been "re-purposed" as clones of the more desirable versions with big-block V8s.

Although it was the longer lived 225 version which gained the Slant Six its stellar reputation for durability and the ease with which additional power could be extracted, there's always been a following for the short-stroke 170 because of its European-like willingness to rev, the characteristics of the over-square engine (unique among the slant-six's three displacements (170-198-225)) unusually lively for a US straight-six.  Despite some aspects of the specification being modest (there were only four main bearings although they were the beefy units used in the 426 cubic inch Street Hemi V8), for much of its life it used a tough forged steel crankshaft and high-speed tolerant solid valve lifters; it proved a was a famously robust engine and one remarkably tolerant of neglect.  Despite that, after the Hyper Pak affair, Chrysler in the US showed little interest in any performance potential, knowing the US preference for V8s, something which doomed also Pontiac's short-lived single overhead camshaft (SOHC) straight-six (1966-1969).  A version of the 225 with a two-barrel carburetor (rated at 160 horsepower, an increase of 15 over the standard unit) was offered in some non-North American markets where V8 sales were not dominant and it proved very popular in South Africa, Australia, New Zealand and Central & South America but only when tighter US emission regulations forced its adoption did a 225 with a two barrel carburetor appear in the home market though there it was installed to restore the power losses suffered after the emission control plumbing was added rather than seek gains.

Pontiac Trophy 4 cutaway.

Making a straight-eight or V8 by combining two in-line fours has been done a few times and many have been successful (although Triumph managed to create a truly horrid one for the otherwise lovely Stag).  Less common is making a four from an eight but that’s what Pontiac did when they conjured their 194.5 cubic inch (3.2 litre) four by using one bank of their 389 cubic inch (6.4 litre) Trophy V8 and it was (just about) literally cut in half, meaning the cylinders were canted to the right by 45^o (the V8 obviously in a conventional 90^o configuration.  To emphasize the family connection with the highly regarded Pontiac Trophy V8, the smaller offspring was called the Trophy 4 (although it was at time also dubbed the Indy 4 or Indianapolis 4 which even at the time sounded ambitious).  It did work and the economic advantages for the manufacturer (use of common components and the same assembly line) were compelling but the limitations inherent in a four-cylinder of such a large displacement were apparent in the rough-running and wear on critical parts and it was available only between 1961-1963, only in the compact Tempest.

Diagram showing balance shaft locations.

Large displacement four cylinder engines have been built.  Fiat in 1910 built two of their S76s to contest the world LSR (land speed record) and they were an hefty 28.4 litres (1730 cubic inch), the “Beast of Turin” using its then impressive 290 horsepower (216 kW) to attain a one-way speed of 132.27 mph (213 km/h) but, because it was not possible for the team to make the “return run” (ie in the opposite direction) within the stipulated one hour, the LSR remained with the Blitzen Benz which in 1909 had set a mark of 125.94 mph (202.65 km/h).  On land, never again would anyone build a four with the capacity to match the Beasts of Turin but units with displacements approaching 5.0 litres (305 cubic inch) were not uncommon during the inter-war years.  However, the technology of the internal combustion engine (ICE) greatly advanced during World War II (1939-1945) and one consequence of that was engine speeds rose and less displacement was required for a specific output, both factors which conspired to make the big fours unfashionable.  They did however make a comeback in the 1970s when the clever trick of “balance shafts” enabled the inherently chronic second order harmonic vibrations to be “dampened out” and Porsche between 1991-1995 produced a 3.0 litre (183 cubic inch) range which used the technique.  The balance shaft was invented early in the twentieth century by English engineer Frederick Lanchester (1868–1946) but it was Mitsubishi which in the 1970s patented their “Silent Shaft” system and although Porsche developed their own version, they worked out the Japanese design was superior so used that instead, paying Mitsubishi a small royalty (under US$10) for each one installed.  A balance shaft uses two counterweights (looking something like small hockey pucks with the shaft running through them), set some 1½ inches (40 mm) apart and turns at twice the engine-speed.  With one shaft mounted high on one side of the engine and the other low on the opposite side, the pair counter-rotates, balancing the large reciprocating mass.  

Trammel

Trammel (pronounced tram-uhl)

(1) A hindrance or impediment to free action or movement; restraint (used usually in the plural as trammels); an inhibition.

(2) An instrument for drawing ellipses.

(3) In engineering, as trammel wheel, a circular plate or a cross, with two or more cross grooves intersecting at the centre, used on the end of a shaft to transmit motion to another shaft not in line with the first.

(4) A device for drawing ellipses consisting of a flat sheet of metal, plastic or wood having, a cruciform slot (a cross with two grooves at right angles to each other) in which run two pegs attached to a beam, the free end of the beam describing an ellipse, usually by means of an attached pencil (known also as a Trammel of Archimedes).

(5) A gauge-like device used to align or adjust parts of a machine (also known as a tram).

(6) A net (for the trapping of fish or birds) in three sections the two outer nets having a large mesh and the middle a fine mesh (also called a trammel net or a fowling net).

(7) A vertical bar with several notches or chain of rings suspended over a fire, used to hang cooking pots by a hook (the mechanism providing a simple means of adjusting the height(s)).  They would originally have been improvised and known also as “trammel rings”.

(8) Braids or plaits of hair (the idea being the “trameling” of the hair in the sense of restraining its natural movement).

(9) An alternative name for the beam compass (often in the plural).

(10) A fetter or shackle, especially one used in training a horse to amble (the trammel tying together each pair of a horse's legs (on the same side), forcing the horse to amble.

(11) To involve or hold in trammels; restrain; to hobble or curb; to obstruct, impede, hinder or encumber; to impose a drag upon.

(12) To catch or entangle in or as in a net.

(13) To hinder or restrain

(14) To catch or ensnare

(15) To produce an accurate setting of a machine (the adjustment not necessarily effected with the use of a trammel).

1325–1375: From the Middle English tramayle, from the Old & Middle French tramail (fine-gauged fishnet, a variant of tremail (three-mesh net)), from the Medieval Latin tramallum, from the Late Latin trēmaculum (assumed to mean “a net made from three layers of meshes”), the construct being the Latin trē(s) (three) + macula (hole; mesh in a net, spot, speck; cell).  It was cognate with the Spanish trasmallo (drift net) and the Italian tramaglio (trammel), both French loan words.  The meaning “anything that hinders” dates from the 1650s, the original sense being the late fifteenth century use to mean “a hobble for a horse”.  In English in the 1580s it was used also to mean a “net for binding up a woman's tresses” (ie a hair-net) while the seemingly curious use as “trammel-wheel” dates from 1877 and picked up the name because the slots were vaguely reminiscent of trammels already in use.  The verb entrammel (to entangle) was in use by the 1590s while the adjective untrammeled dates from at least the 1790s and is the form of the word in widest use today (in the sense of “unhindered; unrestricted”).  The verb in the figurative sense of “hinder; restrain” dates from 1727 and developed from the idea of “binding a horse’s legs with a trammel”, a technique first noted in the late sixteenth century.  The earlier use of the verb was to describe “the binding of a corpse”, first noted in the 1530s.  Trammel & trammeling are nouns & verbs, trammeler is a noun and trammeled is a verb; the noun plural is trammels.

Because of the way Google harvests data for their ngrams, they’re not literally a tracking of the use of a word in society but can be usefully indicative of certain trends, (although one is never quite sure which trend(s)), especially over decades.  As a record of actual aggregate use, ngrams are not wholly reliable because: (1) the sub-set of texts Google uses is slanted towards the scientific & academic and (2) the technical limitations imposed by the use of OCR (optical character recognition) when handling older texts of sometime dubious legibility (a process AI should improve).  Where numbers bounce around, this may reflect either: (1) peaks and troughs in use for some reason or (2) some quirk in the data harvested.

Lindsay Lohan with trammeled hair (braids are plaits can be so described because the hair is being “restrained”).

The multiple (and often disparent (in the obsolete sense)) meanings of “trammel” are an example of the way in English language evolves, words developing new meanings through processes like metaphorical extension, functional shift, and semantic broadening.  The original use was to describe a type of fishing net with three layers and this idea of “catch or entangle” was later used by metaphorical extension to refer to things restricting or hindering movement (as a net certainly does to confined fish).  Over time, this led to many meanings related to restraint, especially in equine training where a “trammel” was an apparatus (made almost always from leather & cord) restricting the movement of a horses legs, compelling them to restrict their gait to an amble.  In engineering, there have been a number of tools in both carpentry and metalworking called “trammel” and they tend to be used either (1) to describe circles or arcs or (2) a gauge-like device used to align or adjust parts of a machine (also known as a tram).  In linguistics, such a process is sometimes described as a “broader semantic shift” but in the matter of “trammel” it was more of a “cumulative build” in that although sometimes any connection to the original seemed remote, there was always some link and from the original fish nets, “trammel” has come to be used of anything that restrains or impedes, whether physical, legal, or metaphorical; the form “untrammeled” (often as untrammelled in non-North American use) now in more common use.

Trammel of Archimedes (an ellipse generator mechanism).

The ellipsograph is a mechanism used to generate the shape of an ellipse and one of the best known is the “Trammel of Archimedes, built with two shuttles which are confined (ie trammeled within) two perpendicular channels or rails and a rod which is attached to the shuttles by pivots at fixed positions along the rod.  As the shuttles move back and forth, each along its channel, the rod moves in an elliptical path and the size of the ellipse described can be varied by the location at which a pencil is attached.  Despite the name, there’s no evidence linking the design to the Ancient Greek polymath Archimedes of Syracuse (circa 287–circa 212 BC) and the name was chosen as a tribute to his seminal contributions to science and engineering, notably his study of the geometry of ellipses.

Apostrophe

Apostrophe (pronounced uh-pos-truh-fee)

(1) The punctuation mark (') used variously: (1) to indicate the omission of one or more letters in a word, whether pronounced or unpronounced, (2) to indicate the possessive case or (3) to indicate plurals of abbreviations and symbols.

(2) In formal rhetoric (as the literary apostrophe), a digression in the form of an address to someone not present, or to a personified object or idea.

(3) In sociolinguistics & orthography, the text character (’) which serves as a punctuation mark in various languages and as a diacritical mark in certain rare contexts.

1525–1535: The use as a rhetorical device was from the Late Latin, from the Classical Latin apostrophe, from the Ancient Greek ἀποστροφή (apostrophḗ) (a turning away; a digression), the construct being apostroph-, verbid of apostréphein (to turn away) + -ē (the noun suffix).  The punctuation mark dates from 1580–1590 and was from the Middle French, replacing the earlier apostrophus, from the Late Latin, from the Ancient Greek ἀπόστροφος (apóstrophos) (accent of elision) (prosōidía) (eliding (mark) (literally “(mark) of turning away”), noun use of an adjective from ἀποστρέφω (apostréphō) (I turn away), verbid of apostréphein, the construct being ἀπό (apó) (away (which sometimes appeared as aph)) + στρέφω (stréphō or stréphein (to turn).  The now rare alternative forms were apostrophë & apostrophy and in non-US use apostrophise etc is more common than apostrophize etc.  Apostrophe & apostrophization are nouns, apostropher, apostrophizing & apostrophize are verbs, apostrophic & apostrophed are adjectives and apostrophically is an adverb; the noun plural is apostrophes.

Lindsay Lohan with pram, JFK airport, New York, January 2024.  In English, names with apostrophes are uncommon (almost all from other languages) but the punctuation mark is sometimes used as a guide to pronunciation.  Ms Lohan named her son (b 2023) Luai which in the Arabic is pronounced Lou’aye with the apostrophe operating as “a kind of break or a cut”.

There are a number of derived terms.  Some are purely descriptive (such as the “curly apostrophe”, the “perpendicular apostrophe”, “vertical apostrophe” and the “straight apostrophe” which in publishing are distinguished as the “typographic apostrophe” (an apostrophe that has a curved, asymmetrical form) (known also as the printer's apostrophe) and the “typewriter apostrophe” (an apostrophe with a straight, vertically symmetrical form).  In sociolinguistics & orthography, the apologetic apostrophe is imposed upon a Scots word in to lend it the appearance of being a contraction of an English word such as wi' (equivalent to the English “with”) and a' (equivalent to the English “all”).  The humorous apostrophectomy is a clinical procedure used by the grammar nazis ruthlessly to excise incorrect apostrophes, usually those used wrongly to form plurals.  The construct was apostrophe +‎ -ectomy (from the Ancient Greek -εκτομία (-ektomía) (a cutting out of), from ἐκτέμνω (ektémnō) (to cut out), the construct being ἐκ (ek) (out) + τέμνω (témnō) (to cut). The reverse procedure (inserting an apostrophe where one is required) was apostrophplant. the construct being apostroph(e) + (in)plant.  The grammar nazis operate usually on the “greengrocer's apostrophe” one where the symbol is used in error when forming a noun plural.  It’s probably a slight on greengrocers in that others are just as guilty but the most commonly cited examples are usually something like “Banana’s, 99c lb” rather than “Vegetarian Burger’s available”.  Among those in England who speak RP (Received Pronunciation, the “correct” form insisted on by the BBC (British Broadcasting Corporation) until the 1960s (with the odd quirky exception)), the greengrocer's apostrophe is still sometimes known as the “Yorkshire apostrophe”; it’s a form of (southern) linguistic snobbery because the phenomenon certainly isn’t unique to those from the county.

The literary apostrophe is a figure of speech in which a thing, a place, an abstract quality, an idea, a dead or absent person, is addressed as if present and capable of understanding. Classic instances include Oliver Goldsmith’s (1728–1774) opening in The Deserted Village (1770): “Sweet Auburn, loveliest village of the plain…”; Antony's cry in William Shakespeare’s (1564–1616) Julius Caesar (1599): “'O Judgement! thou art fled to brutish beasts…”; William Wordsworth’s (1770–1850) passionate appeal in London 1812: “Milton! Thou should'st be living at this hour…” and the biblical: “O death, where is thy sting? O grave, where is thy victory?” (1 Corinthians 15:55; King James Version (KJV, 1611)).

As a mark indicating “an omitted letter”, the apostrophe was in common (though far from universal) use by the early sixteenth century and the origin of use as a possessive marker lay in one representing the loss of -e- in words ending in –es; by the mid eighteenth century, it was being applied to all possessives, whether or not they were ever once spelled with an additional “e”.  Another of the grammar nazis bugbears (they have many) is the incorrect use of “it’s” as a neuter possessive pronoun, the late sixteenth century construct being it + the genitive/possessive ending “'s”.  The correct use of “it’s” is as a contraction of “it is” etc but as a possessive form it endured until the early nineteenth century and etymologists suggest the decline in use was due to either because the contraction of “it is” had become established or to align use with the general practice of omitting apostrophes in personal pronouns (yours, hers, theirs et al.).  One of the best known instances of a word with a “apostrophe substitution” appears in Shakespeare’s Romeo and Juliet (1597) where “star cross’d lovers” is used to describe the doomed pair.

1967 Ford Mustang (left), 1970 Plymouth 'Cuda (the 1971 grill an aesthetic choice and the apostrophe indicating a clipping of “Barracuda”, the model designation used on the non high-performance models) (centre) and 1968 Chevrolet Camaro (right) at the Pikes Peak International Hill Climb (PPIHC) (the “Race to the Clouds”).  The three compete in the "Vintage Car" class.  The PPIHC is a marvelously anarchic event, run continuously since 1916 (except in 1917-1919 & 1942-1945 because of wartime restrictions) and an example of how good things can be if the FIA (the Fédération Internationale de l'Automobile (International Automobile Federation), world sport’s dopiest regulatory body) isn’t involved.

Pikes Peak in the US state of Colorado was in 1820 named (as Pike’s Peak) after Brigadier General Zebulon Pike (1779–1813) who led an earlier expedition (which failed to reach the summit).  It a shame the landmark wasn't named "Zebulon's Peak"; so much more evocative.  The name Zebulon was from the Latin Zabulon, from the Ancient Greek Ζαβουλών (Zaboulṓn), from the Biblical Hebrew זְבוּלוּן (z'vulún).  In the Hebrew, Zebulon was a male name meaning “exalted house,” “dwelling,” “lord,” or “prince” (the alternative spelling was Zebulun.  In biblical times, Zebulun was one of the twelve tribes of Israel and it was the given name for the sixth son of Jacob and his wife, Leah.  Prior to European settlement, the native peoples of the region called the peak variously Tava (Sun) or Heey-otoyoo' (Long mountain).  In 1890, the US Board on Geographic Names (BGN) introduced a policy avoiding the use of apostrophes in the possessive form in place names, the intent being: (1) a standardization convention to remove confusion, (2) to simplify the printing of maps by ensuring there were fewer clashes with special characters and (3) to remove another source of imaginative interpretation by lawyers.  An additional benefit was realized when computer databases began to be created and, especially in the early post-war years, many problems in indexing and formatting were avoided by restricting entries to letters & numbers.  In 1890, Pike’s Peak thus became Pikes Peak and just to make sure no grammar Nazis ever attempted a revival, in 1978 the Colorado state legislature outlawed the use of an apostrophe in Pikes Peak, apparently one of the world’s few laws about punctuation.  The BGN does make the odd exception in the case of places of historical significance and Martha's Vineyard was one of the few places to emerge with apostrophe intact.  

It’s a pity the BGN doesn’t set the other rules for the use of the apostrophe, a matter which so concerned Henry Fowler (1858–1933) that he devoted several paragraphs to the topic in A Dictionary of Modern English Usage (1926).  One helpful reform would be to standardize the placement when making a possessive of names ending in “s” and that rule should be: (1) when a name ends in a letter other than “s” the apostrophe sits before the appended (plural) “s” (Lindsay Lohan’s car) and (2) when a name ends in “s” the apostrophe follows (the so-called “trailing apostrophe”) (Britney Spears’ car).  That has the benefit of simplicity and would mean one wouldn’t have to choose between the various options published in style guides, some of which are based on the number of syllables and some on the sound of the word when pronounced.  It’s a layer of complication as unnecessary as adding pronunciation guides to printed numbers (1^st, 2^nd, 3^rd, 4^th etc) in that it’s a needless tribute by the written to the spoken; the human brain can manage without them.

Kamala Harris (b 1964; US vice president since 2021) and Tim Walz (b 1964; governor of Minnesota since 2019), on stage, Philadelphia, Pennsylvania, 6 August 2024.

The issue flared when Kamala Harris announced Tim Walz as her running mate in the 2024 US presidential election for not only does “Harris” end in “s” but “Walz” when spoken sounds like it too ends thus, something which style guides variously suggest should exist in the possessive either as Walz’s or Walz’.  Clearly, he’s a trouble-maker.  Most of the grammar nazis (X (formerly known as Twitter) their natural home where debate ensued) seemed to conclude “Walz’s” was correct but Harris’ or Harris’s divided opinion, the factions forming to defend either (1) if the “s” is sounded, spell the “s” and (2) if it ends in an “s” regardless of pronunciation, it’s a trailing apostrophe.  Most dictionaries say either practice is acceptable provided use is consistent which is fence-sitting but reflects reality although there is the sense many editors would be happy if a universal appended “’s” was the “rule” so the tiresome debate would go away.  Presumably that would also please the Harris-Walz campaign team which has issued press releases which included “Harris’s positive vision” and “Harris’ seventh trip to Nevada.”

Henry Fowler’s A Dictionary of Modern English Usage has been influential for almost a century and it’s the original and the second edition (1965) edited by Sir Ernest Gowers (1880–1966) which remain the standard (the third (1996) and fourth (2015) editions less helpful although some readers might appreciate being “spoken with” rather than “dictated to” as was Henry Fowler’s way).  However, in the TikTok age, it may prove the singer Taylor Swift (b 1989) is now the final arbitrator of the language’s squabbles.  In mid 2024, MS Swift released the album The Tortured Poets Department and while most (Swifties and others) focused on the music, some couldn’t help but notice what appeared to be the “missing apostrophe”.  However, whether or not it’s missing depends on how the title is read:  If it's a possessive form then one should appear but if “poets” is operating as descriptive modifier of “department” then none is required.  Understanding the distinction is easiest if the phrase is deconstructed and imagined as a department in a university which contains tortured poets; there morosely they sit for a time but they don’t “possess” the department; instead, tortured poets come and go and over generations the membership changes but the department endures.  In that sense, Ms Swift’s "Tortured Poets Department" is like a "Farmers Market" rather than a "driver’s license".  So, it’s really a matter of what Ms Swift intended and she seems a bit of a word nerd so it may be assumed she says what she means and means what she says.

Boomerang

Boomerang (pronounced boo-muh-rang)

(1) A bent or curved piece of tough wood used by some of the Indigenous peoples of Australian as a throwing stick (and for other purposes), one form of which can be thrown so as to return to the thrower.  Such throwing sticks have also been found in archaeological digs in other places.

(2) Based on the use Indigenous peoples of Australia, an object in the shape of a flat curved air-foil that spins about an axis perpendicular to the direction of flight, used for various purposes including sport, training and aeronautical purposes.

(3) In design, anything using the boomerang shape (not always symmetrically)

(4) Something which in flight assumes the shape of a boomerang, such as the “boomerang kick” in certain football codes.

(5) In theatre and other stage environments, a mobile platform (mobile and height-adjustable) used for setting or painting scenery.

(6) In theatre and other stage environments, a batten, usually suspended vertically in the wings, used for mounting lighting units.

(7) In theatre and other stage environments, a device for changing the color of a follow-spot(light).

(8) In psychology, as “boomerang effect”, a strong opposing response caused by attempts to restrict a person's freedom or change their attitudes.

(9) In pathology, as “boomerang dysplasia”, a lethal osteochondrodysplasia in which the bones of the arms and legs are congenitally malformed into the shape of a boomerang.

(10) In air force (originally Royal Air Force (RAF)) slang, the early return of an aircraft from an aborted mission, often attributer to mechanical or other technical problems.

(11) A cocktail made with rye whiskey and Swedish punsch.

(12) Figuratively, something or someone which come backs or returns (as the boomerang behaves when correctly thrown) and when applied to people used especially of those who habitually return (often as “serial boomeranger”).

(13) Something (physical and otherwise, such as a scheme, statement or argument) which causes harm to the originator (the idea of a “rebound” or “backfire”).

(14) The action of coming back, returning or backfiring:

1827: From būmariny (missile weapon used by Aborigines), the recorded phonetic form of a word in one of the now extinct languages spoken by the Dharuk people native to an area in New South Wales now known to geographers as the Sydent basin.  A word pronounced as wo-mur-rang was noted in NSW in 1798 which may have been related but there’s no documentary evidence.  Boomerang is a noun & verb; boomeranger is a noun, boomeranged & boomeranging are verbs, the noun plural is boomerangs.

The verb use in the sense of “throw a boomerang” seems to have come into use in the 1800s while the figurative sense of “fly back or return to a starting point” was in use by the early twentieth century.  A “boomerang baby”, “boomerang child” or boomerang kid” is one who returns to live in the family home after a period of independent living and known collective as the “boomerang generation”, the phenomenon noted in many countries and associated with financial distress, related especially to the cost of housing.

For the Indigenous (Aboriginal) peoples of Australia, the boomerang is as old as creation and since white settlement it has become also a symbol of the enduring strength of Aboriginal culture.  Although no written form of language (in the structured sense used elsewhere) evolved among them, an oral tradition now known “the Dreaming” (apparently no longer “Dreamtime”) extends from the past into the present. In the Dreaming, many of the physical formations of the (lakes, rivers, rock structures, mountains etc) were created when Ancestors threw boomerangs and spears into the earth.  Although the boomerang of the popular imagination is the familiar chevron shape, during the nineteenth century almost 300 language groups were identified by anthropologists and the construction of boomerangs varied, the divergences dictated mostly by the prevailing environment: Larger, heavier boomerangs were associated with inland and desert people while the lighter versions were thrown by coastal and high-country inhabitants.  Despite the perceptions, most were of the non-returning variety and were used as hunting weapons for the killing of birds and game including emu, kangaroo and other marsupials.  Not only was the boomerang a direct-impact device but the technique was also noted of a hunter making a boomerang ricochet off the ground to achieve an ideal angle.  The early observers recorded in skilled hands (and over thousands of years those skills would have been well-honed) the boomerang could be effective when hunting prey at a range up to 100 yards (90 m).

Back To Me (Cavalier's Boomerang Club Mix, 2020) by Lindsay Lohan.

Combination tactics were also observed.  When hunting for birds, a returning boomerang might be thrown above a flock of ducks to simulate the effect of a hovering bird of prey, inducing fright which would make the birds fly into nets set up in their flight path or, if within range, a hunter could cast a non-returning boomerang in the hope of a strike.  A special application and one which relied on a design with none of the famous aerodynamic properties was in the harvesting of fish, heavy boomerangs effective killing weapons of in areas of high tidal variation where fish became trapped in rock pools.   They were also Battle-weapons, used both to throw from some distance and in close combat, the types seen including small, hand-held “fighting sticks” device and some even two yards (1.8 m) in length.  Remarkably, the much the same implements served also as digging sticks used to forage for root and could be used to make fire, the familiar idea of “rubbing sticks together”.  Although these practical may have declined in significance as Western technology has been absorbed, boomerangs remain a prominent feature in Aboriginal dance and music.

Since the techniques developed for the shaping of Perspex and other plastics were (more or less) perfected during World War II (1939-1945), they’ve been widely adopted in industrial mass-production, for better and worse.  One thing made possible was boomerang-shaped taillights on cars which for years were about the most avant-garde of their type although of late, designers have been unable to resist the contortions and complexity made possible by the use of LEDs (light emitting diode).  Some critics insist the “boomerang” tag should be applied only to something in the shale of the “classic” boomerang and that anything asymmetric is properly a “hockey stick” but most seem content with the label.

Top row, left to right: 1969 Pontiac Bonneville, 1970 Hillman Avenger and 1967 Plymouth Barracuda.  Those which point "up" probably work better than those pointing "down" because the latter imposes a "droopiness".

Middle row, left to right: 1967 Chrysler Valiant VE Safari (Wagon), 1967 Chrysler Valiant VE Sedan and 1962 Pontiac Bonneville.  Strangely, although the sedan and wagon versions of the VE Valiant both used the boomerang shape, the moldings were different.

Bottom row, left to right: 1958 Edsel Bermuda station wagon, 1960 Chrysler New Yorker and 1975 Mazda RX-5.  The Edsel's tail lights worked as indicators and because the boomerang shape had link with the detailing on the rear quarter panels, when flashing, they actually "point" in the direction opposite to which the car is turning.  It was a harbinger of the Edsel's fate.

Louis Vuitton’s Fall 2014 campaign shoot with 1972 Maserati Boomerang, Giardini della Biennale, Venice.

The photo-shoot for Louis Vuitton’s Fall 2014 campaign at Venice’s Giardini della Biennale featured the 1972 Maserati Boomerang concept car.  Coordinated by Nicolas Ghesquière (b 1971; LV's women's creative director since 2013) and shot by German photographer Juergen Teller (b 1964), it was a rare appearance of the Boomerang which, designed by Giorgetto Giugiaro (b 1938), had first appeared at the Turin Motor Show as a static mock-up in Epowood (a versatile epoxy used for forming shapes) before being engineered as a fully-finished and working vehicle, built on the underpinnings of a Maserati Bora (1971-1978).  In that configuration it was displayed at the 1972 Geneva show where it was understood as one of the “high-speed wedges” of an era which included the original Lancia Stratos, the Lotus Esprit and, most influentially of all, the Lamborghini Countach, the cluster defining the template around which exotic machines would for decades be built, the design motif still apparent in today’s hypercars.  Eye-catching from the outside, the interior also fascinated with a steering wheel and gauge cluster built as a single console emerging from a distant dashboard, the wheel rotating as the gauges remained stationary.

1972 Maserati Boomerang by Giorgetto Giugiaro.

It was Italdesign, founded by Giorgetto Giugiaro which designed the Maserati 3200 GT (Tipo 338; 1998-2002), a car which, although not exciting in a way many of the marque’s earlier models had been, was an important element in the establishing Maserati’s twenty-first century reputation for functionalism and quality.  Importantly, although in production for only four of the transitional years during which ownership of the brand passed from Fiat to Ferrari and the solid underpinnings would be the basis for the succeeding Coupé and Spyder (4200 GT, Tipo M138; 2001-2007).

It was on the 3200 GT that Italdesign used tail-lights in the shape of a boomerang, much comment upon at the time but also a landmark in that they were the first production car to be sold with taillights which were an assembly of LEDs, the outer layer the brake lights, the inner the directional indicators (flashers).  Following the contours of the bodywork and integrated with the truck (boot) lid, they were the most memorable feature on what was otherwise an inoffensive but bland execution which could have come from any factory in the Far East.  They generated much publicity but it’s hard to argue they’re better looking than the classic four round lenses known from many of the best Italians.  Like architects, designers seem often drawn to something new and ugly rather than old yet timeless, the former more likely to attract the awards those in these professions award one-another.

Northrop YB-49 in flight, California, 1952.

The aerodynamic properties of the “flying wing” have long intrigued aircraft designers.  The USAF (United State Air Force) even contemplated putting into production on of Northrop’s design but in the mid-1940s, needing a delivery system for its nuclear bombs which was a known, reliable quantity, opted instead for the Convair B-36 which they acknowledged was obsolescent but would provide a serviceable stop-gap until wings of the upcoming Boeing B-52 could be formed.  That doubtlessly was the correct decision and in the decades since, neither a military or civilian case has been made for the “flying wings”, the machines which have entered service really variations on the proven delta-wing concept but the big Northrop YB-49 & XB-35 possessed an undeniable beauty and it’s a shame all were scraped by 1953.  The air force personnel actually preferred to call them “bat bombers”.
