Stiletto

Stiletto (pronounced sti-let-oh)

(1) A small, slender knife or dagger-like weapon intended for stabbing; usually thick in proportion to its width.

(2) An archaic name for the rapier.

(3) A pointed instrument for making eyelet holes in needlework; a sharply pointed tool used to make holes in leather; also called an awl.

(4) A very high heel on a woman's shoe, tapering to a very narrow tip, also called the spike heel or stiletto heel.

(5) A beard trimmed to a pointed form.

(6) A style used in the fashioning of decorative fingernails.

1605–1615: From the Italian stiletto, a doublet of stylet, the construct being stil(o) (dagger or needle (from the Latin stilus (stake, pens))) + -etto (-ette) and from the Latin stilus came also stelo, an inherited doublet.  The etto- suffix was used to forms nouns from nouns, denoting a diminutive.  It was from the Late Latin -ittum, accusative singular of –ittus, and was the alterative suffix used to form melioratives, diminutives, and hypocoristics and existed variously in English & French as -et, in Italian as Italian -etto and in Portuguese & Spanish as -ito.  With an animate noun, -etto references as male, the coordinate female suffix being -etta, which is also used with inanimate nouns ending in -a.  It should not be confused with the homophonous suffix -eto.  Stilus was from the primitive Indo-European (s)teyg- (related to instīgō & instigare) and was cognate with the Ancient Greek στίζω (stízō) (to mark with a pointed instrument) and the Proto-Germanic stikaną (to stick, to stab).  Despite the similarity, there’s no relationship with the Ancient Greek στῦλος (stûlos) (a pillar).

A quasi-technical adoption in law-enforcement and judicial reports were the verb-forms stilettoed & stilettoing, referring to a stabbing or killing with a stiletto-like blade.  It was a popular description used by police when documenting the stabbing by wives of husbands or boyfriends with scissors or kitchen knives; use faded in the mid-twentieth century.  The idea of a long, slender beard trimmed into a pointed form being "a stiletto" popular in the sixteenth & seventeenth centuries but all such forms seem now to be referred to either as "a goatee" or "a Van Dyke".  The adjectival use can also sometimes need to be understood in the context of the phrase or sentence: "a stilettoed foot" can be either "the foot of someone wearing a shoe with a stiletto heel" or "a foot which has been stabbed with a long, thin blade.  Stiletto & stilettoing are nouns & verbs, stilettoed is a verb & adjective and stilettolike (also stiletto-like) is an adjective; the noun plural is either stilettos or stilettoes.

Of blades and heels

The stiletto design for small bladed weapons pre-dates not only modern metallurgy but antiquity itself.  The essence, a short, relatively thick blade, was technologically deterministic rather than aesthetic, most metals of the time not being as sturdy as those which came later.  Daggers were for millennia an essential weapon for personal protection but, particularly after developments in ballistics; they tended to evolve more for formal or ceremonial purposes.

The Schutzstaffel (SS) dagger model M1933 (often abbreviated to M33).

The M1933 was the standard issue to all SS members, the hilt either silver or nickel-plate while the grip was black wood.  Produced in large numbers, collectors are most attracted to the low-volume variations such as those without the manufacturer’s trade-mark or RZM control markings.  Most prized are the rare handful with a complete "Ernst Röhm inscription" which read In herzlicher freundschaft, Ernst Röhm (In heartfelt friendship, Ernst Röhm).  Given his his habits, enjoying Röhm's "friendship" would for a few have proved a double-edged sword.   Some 136,000 of the engraved SA daggers were produced, a further 9900-odd distributed to the SS.  After Röhm (1887–1934; chief of the Nazi Sturmabteilung (the stormtroopers (the SA)) was executed during the Nacht der langen Messer (Night of the Long Knives), also called Unternehmen Kolbri (Operation Hummingbird) in 1934, all holders of the Röhm Honour Dagger were ordered to have the inscription removed and most complied, the unmodified survivors thus highly collectable although in some countries, the very idea of trading Nazi memorabilia is becoming controversial.  As ceremonial devices, bladed weapons were a feature of the uniforms worn during the Third Reich (1933-1945) and they were issued to all branches of the Wehrmacht (the German armed forces) the police, the various paramilitaries, the diplomatic service as well as organizations as diverse as the railways, the fire services, the forestry service and the postal office.  In this they were continuing a long German tradition but the Nazis vision of a homogenous, obedient population included the notion that uniforms should be worn wherever possible and there is something in the cliché that (at least at the time), no German was ever as happy as when they were in uniform.

Although the term is used widely, in the narrow technical sense, not all slim, high heels are stilettos.  The classic stilettos were the extremely slender Italian originals produced between the 1930s and 1960s, the heels of which were no more than 5 mm (0.2 inch) in diameter for much of their length, flaring at the top only to the extent structurally required successfully to attach to the sole; the construction of solid steel or an alloy.  Many modern, mass-produced shoes sold as "stilettos" are made with a heel cast in a rigid plastic with an internal metal tube for reinforcement, a design not having the structural integrity to sustain the true stiletto shape.  However, English is democratic and in the context of footwear, "stiletto" now describes the visual style, regardless of the materials.

The lines of the classic black stiletto (top left) were long ago made perfect and can't be improved upon; such is the allure that many women are prepared to endure inconvenience, instability, discomfort and actual pain just to wear them.  They appeal too to designers and the style, the quintessential feminine footwear, has been mashed-up with sneakers, Crocs, work-boots, sandals and even a scuba-diver's flippers (though they really were at home only on the catwalk).  Military camouflage is often seen, designers attracted by the ultimate juxtaposition of fashion and function.  The Giuseppe Zanotti Harmony Sandals (bottom row, second from right) were worn by Lindsay Lohan on The Masked Singer (2019).    

In the world of fingernail fashioning, there are stilettos and stilettos square.  A statement shape, something of a triumph of style over functionally, the stiletto gains its dramatic effect from long and slender lines and can be shaped with either fully-tapered or partially square sides.  They’re vulnerable to damage, breaking when subjected to even slight impacts and almost never possible with natural growth and realistically, pointed nails, certainly in their more extreme iterations (the stilettos, lipstick, mountain peaks, edges, arrow-heads, claws or talons), are more for short-term effect than anything permanent.  Best used with acrylics, the knife-like style can be a danger to the nail itself and any nearby skin or stockings.  Those contemplating intimacy with a women packing these should first ponder the implications.  True obsessives insist the stiletto styles should be worn only with matching heels and then only if the colors exactly match.

1964 Hillman Imp.

The Hillman Imp was a small economy car introduced in 1964.  It was the product of the Rootes Group which needed an entry in a market segment which had been re-defined by the British Motor Corporation’s (BMC) Mini and although similar in size, the engineering was radically different: rather than the Mini's front-engine / front wheel drive (FWD) arrangement which became (and to this day remains) the template for the industry, the Imp was configured with a rear-engine and rear wheel drive (RWD), something which had for decades been a feature of small Europeans cars but was in the throes of being abandoned.  It never achieved the commercial success of the BMC product although it continued in production after 1967 when the Rootes group was absorbed by Chrysler and, perhaps remarkably, it remained on the books until 1976.  In that time, it sold in not even 10% of the volume achieved by the Mini between 1959-2000.

Hillman Imp V8, Oran Park, Sydney, Australia, 1971.

The Hillman Imp did enjoy some success in competition, winning three successive British Saloon Car Championships between 1970-1972 (competing in Class A (under 1000 cm³)) but years earlier, its light-weight and diminutive dimensions had appealed to Australian earth-moving contractor Harry Lefoe (1936-2000) who had a spare 302 cubic inch (4.9 litre) Ford (Windsor) V8 sitting in his workshop.  By then, the Imp was a Chrysler product but because the published guidelines of the Australian Sports Sedan Association (ASSA) restricted engines to those from cars built by the manufacturer of the body-shell, the small-block Ford V8 could be put in an Imp because it had been used in the earlier Sunbeam Tiger.  So the big lump of an iron V8 replaced the Imp's 875 cm³ (53 cubic inch) aluminium four and such was the difference in size that Lefoe insisted his Imp had become "mid-engined" although it seems not to have imparted the handling characteristics associated with the configuration, the stubby hybrid infamous for its tendency to travel sideways.  It was never especially successful but it was loud, fast, spectacular and always a crowd favourite.

1967 Sunbeam Stiletto.

Introduced in 1967, the Sunbeam Stiletto was a “badge-engineered” variant of the Imp (there were also Singers), the name an allusion to the larger Sunbeam Rapier (a stiletto a short blade, a rapier longer).  Badge engineering (a speciality of the British industry during the post-war years) was attractive for corporations because while it might increase unit production costs by 5-10%, the retail price could be up to 40% higher.  Very much a “parts-bin special” (although there was the odd unique touch such as the quad-headlamps and the much-admired dashboard), mostly it was a mash-up, the fastback bodywork already seen on the Imp Californian and some interior fittings and the more powerful twin carburettor engine shared with the Singer Chamois.  Curiously, some sites report the fastback lines proved less aerodynamically efficient than the Imp’s more upright original, the opposite of what was found by Ford in the US when the “formal roof” Galaxies proved too slow on the NASCAR ovals, a “semi-fastback” at essentially the same angle as the Stiletto proving the solution; the physics of aerodynamics can be counter-intuitive.  Stiletto production ceased in 1972 with the Sunbeam brand-name retired in 1976 although Chrysler used it as a model name until 1981.

Dagger

Dagger (pronounced dag-er)

(1) A short, double-edged weapon with a pointed blade and a handle, used historically for personal protection in close combat (although some were weighted for throwing), but since the development of side-arms, increasing only for ceremonial purposes (many produced without sharpened edges).

(2) In typography a mark (†) used to indicate a cross reference, especially a footnote (also called obelisk).  The double dagger (‡) is also used.

(3) In sport and military strategy, a offence which thrusts deep into opposition territory on a short front.

(4) In glaciology, the long, conical ice-formations formed from drops of water (al la the stalactites in caves).

(5) In the slang of clinical medicine, anything that causes pain like a stabbing injury (typically, some sort of barb)

(6) In basketball & American football, a point scored near the end of the game (clutch time) to take or increase the scorer's team lead.

(7) In nautical architecture, as daggerboard, a retractable centre-board that slides out to act as a keel; a timber placed diagonally in a ship's frame.

(8) To stab with a dagger or similar bladed weapon (archaic).

(9) In typography, to mark with a dagger (obelisk).

1380s: From the Middle English daggere, daggare & dagard, probably an adaptation from the thirteenth century Old French dague (dagger), from the Old Provençal or Italian daga of obscure origin but related to the Occitan, Italian & Spanish daga, the Dutch dagge, the German Degen, the Middle Low German dagge (knife's point), the Old Norse daggarðr, the Danish daggert, the Faroese daggari, the Welsh dager & dagr, the Breton dac and the Albanian thikë (a knife, dagger) & thek (to stab, to pierce with a sharp object).  Etymologists have speculated on the source of dagger, some suggesting a Celtic origin.  Others prefer the unattested Vulgar Latin daca & dacian (knife) (the name from the Roman province), from the Classical Latin adjective dācus while an entry in an eighteenth century French dictionary held the French dague was from the German dagge & dagen (although not attested until much later).  More speculatively still is the notion of some link with the Old Armenian դակու (daku) (adze, axe), an alternative to which is some connection with the primitive Indo-European dāg-u-, suggesting something cognate with the Ancient Greek θήγω (thḗgō) (to sharpen, whet).  Dagger is a noun & verb, daggering is a noun & verb, daggerman & daggerpoint are nouns, daggerlike is an adjective and daggered is a verb; the noun plural is daggers.

The association of the dagger with knightly weaponry can be traced back to French writings in the twelfth century while the other Middle Latin forms included daga, dagga, dagha, dagger, daggerius, daggerium, dagarium, dagarius & diga (the words with the -r- being late fourteenth century adoptions of the English word.  The Oxford English Dictionary (OED) lists an English verb dag (to stab) from which dagger as a verb could be derived but the verb is attested only from the turn of the fifteenth century.  Long used as a weapon of personal protection, skilled sixteenth & seventeenth century swordsmen would use one in their other (usually left) hand to parry thrusts from the opponent's rapier.  It was a high-risk technique.  The use in texts as a reference mark (also called the obelisk) dates from 1706.  The wonderfully named “bollock dagger” was a dagger with a distinctively shaped shaft having two oval swellings at the guard resembling the male testes.  The polite term was “kidney dagger”.  An “ear dagger” was used in the late medieval period and gained the name from its distinctive, ear-shaped pommel.  In slang, to be “stabbed with a Bridport dagger” was to be executed by hanging, the origin of that being the district of Bridport in Dorset being a major producer of the hemp fibre used in the production of the ropes used by hangmen.  In idiomatic use, to “look daggers at” is to stare at someone angrily or threateningly, something one would do if “at daggers drawn” (in a state of open hostility) with them.

Lindsay Lohan in stiletto heels, February 2009.  Whether much would have changed in the fashion business if the style of heel had come to be known as "dagger" instead of "stiletto" is unlikely.

Other names for the short bladed weapon included stiletto & poniard.  Stiletto was from the Italian stiletto; doublet of stylet, the construct being stil(o) (dagger or needle (from the Latin stilus (stake, pens))) + -etto (-ette).  From the Latin stilus came also stelo, an inherited doublet.  Stilus was from the primitive Indo-European (s)teyg- (related to instīgō & instigare) and was cognate with the Ancient Greek στίζω (stízō) (to mark with a pointed instrument) and the Proto-Germanic stikaną (to stick, to stab).  Despite the similarity, there’s no relationship with the Ancient Greek στῦλος (stûlos) (a pillar).  The -etto suffix was from the Late Latin -ittum, accusative singular of –ittus and was an alternative suffix used to form melioratives, diminutives and hypocoristics.  The noun plural is either stilettos or stilettoes and stilettolike (appearing also as stiletto-like) is an adjective.  A technical adoption in law-enforcement and judicial reports were the verb-forms stilettoed & stilettoing, referring to a stabbing or killing with a stiletto-like blade.  It was a popular description used by police when documenting the stabbing by wives of husbands or boyfriends with scissors or kitchen knives; use faded in the early twentieth century.  The use of “stiletto heel” to describe the elegant, narrow high heel in women's shoes dates from as recently as 1953.  Poniard (a dagger or other short, stabbing weapon) dates from the 1580s and was from the early sixteenth century French poinard, from the Old French poignal (dagger (literally “anything grasped with the fist”)), from poing (fist), from the Latin pungus (a fist (a pugio being “a dagger”)), from a suffixed form of the primitive Indo-European root peuk- (to prick).  It’s thought it was probably altered in French by association with poindre (to stab).  It was used a verb from the turn of the seventeenth century in the sense of “to stab with or as if with a poniard”.

Hermann Göring (1893–1946; leading Nazi 1922-1945, Hitler's designated successor & Reichsmarschall 1940-1945) in Luftwaffe Field Marshal’s uniform with baton and sword (1938, left) and in Luftwaffe General’s uniform with ceremonial dagger (right).  The baton would be replaced with an even more extravagant, jewel-encrusted creation when in 1940 he was appointed Reichsmarschall and it's now on display in the US Army's West Point Museum at Highland Falls, New York.  Convicted of war crimes and crimes against humanity, Göring was hanged in 1946. 

The dagger shown (right) is a standard 1935 issue for Luftwaffe officers.  Updated in 1937 and fashioned always with a 260 mm (10¼ inch) blade, the pommel and crossguard were aluminum, bearing the swastika (occasionally finished in anodized gold) on the pommel face with a Luftwaffe flighted eagle and swastika on the crossguard.  The grips were celluloid over a word base and in various production runs they were finished in colors ranging from pure white to a deep orange.  The scabbards were all in anodized grayish blue steel with a striped decoration on the body face with an oak leaf pattern on the face of the drag.  Worn suspended from straps bearing twin silver stripes on a dark grayish blue background with square buckles, it featured a short aluminum cord knot.  In an example of the expanding list of recipients entitled to wear a dagger, after 1940, authorization was extended to non-commissioned officers though without the portepee (the sword-knot which denoted an officer’s right to bear a sword).  The sword word by Göring (left) was a bespoke one-off manufactured by the Eickhorm company to mark his wedding on 10 April 1935.  The pommel was engraved with a facsimile of the Pour Le Merite (the “Blue Max”) Göring was awarded during his service as a pilot with the Jagdgeschwader 1 (better remembered as Manfred von Richthofen’s Flying Circus).

Germans have long adored uniforms and especially prized are the accessories, among the most distinctive of which are ceremonial daggers.  During the Third Reich, a period in which many institutions of state were increasingly re-ordered along military lines, the issuing of ceremonial daggers was at its most widespread and in addition to the expected recipients in the army, navy & air force, the SS, the SA, the Hitler Youth, the diplomatic service and the police, they were also part of the uniforms of organizations such as the fire department, the postal & telegraph service, the forest service, the labor service, the customs service the railway & waterways protective service and the miners association.  While it’s true that in Germany daggers had in the past been issued even to civilians, under the Nazis the scale and scope proliferated.

Masonic daggers.

Among their many mysterious rituals, the Freemasons also have their own lines of daggers which they claim are purely “ceremonial” but because all that they do is so shrouded in secrecy, the true nature of their purpose isn’t known.  It is however believed that the styles of daggers conferred reflect the grades and offices which evolved from the medieval craft guilds and presumably, the more exalted one’s place in the Masonic hierarchy, the more elaborate the dagger to which one is entitled.  Top of the pile in a Masonic Lodge is the Worshipful Master, other intriguing titles including Senior Warden, Junior Warden, Chaplain, Senior Deacon, Junior Deacon, Steward, Tyler, Mentor and Almoner.  Whether all get their own daggers or some share with others are among the many mysteries of Freemasonry.  Of the even more opaque Secret Society of the Les Clefs d’Or, nothing is known about whether their rituals include the use of daggers, ceremonial or otherwise.

Squoval

Squoval (pronounced sqwoh-vuhl)

(1) In cosmetology, a description applied mostly to describe the shape of certain fingernails and faces; essentially an oblong (a rectangle with partially ovoid shorter sides).

(2) In commerce, a trademark of the bicycle company Cervélo, describing the cross sectional shape of a downtube used in frame construction.

1984: A portmanteau word, sq(uare)- + oval.  Square is from the Middle English square, sqware & squyre from the Old French esquarre & esquerre, (which survives in modern French as équerre), from the Vulgar Latin exquadra, derived from the Latin quadro, from quadrus (square), from quattuor (four).  Oval is from the Late Latin ovalis, from ovum (egg); it was cognate with the French and Italian ovale and the Dutch ovaal.  Used both as noun and adjective, coinage is credited to Paula Gilmore, a noted manicurist.

Art of the fingernail

A pleasing creation, sqoval is misleading because it’s used to reference a shape which is actually a rectangle with the shorter sides defined by curves which tend to the semi-circular.  In geometry, such a shape is called a stadium, discorectangle or an obround.  It’s not to be confused with a square with rounded corners which is a quartic, the mathematically perfect expression of which is Lamé's special quartic.

Squoval is thus a commercial descriptor in the fingernail business rather than a precise geometric description.  The basic rectangle metaphor is important in fingernail shaping because manicurists borrow from art and architecture the golden ratio which suggests humans find most aesthetically pleasing, shapes with an aspect ratio of about 1.6:1 which, coincidentally, is the relationship between a kilometre and a mile.  Nails can be shaped beyond the nominally perfect 1.6:1 but tend either to be thought exaggerated or created purely for artistic display, often to create a large surface for designs.

Manicurists, certainly in the Instagram age, are an imaginative profession and there’s been a proliferation of terms to describe species.  However, within the fingernail family, there are eight basic genera, practitioners inventing or classifying species as they emerge.  To date, the lipstick is the only defined form which is asymmetric.

The classic oval is said to be a symmetrical ellipse where the curve of the tip exactly mirrors the curve of the cuticle but, in real-world conditions, the former usually only tends to the latter.  The shape is natural, flattering and adaptable to both long and short nails.

Long coffins.

A natural coffin demands long nails with the fragility that implies.  The nail needs to be sufficiently long so both sides can be filed to a tapered point something like a stiletto before the tip is squared-off.  Because of that, they’re often constructed with acrylics.  Coffin in this context is actually a modern appropriation to describe what was historically known as the ballerina, a descriptor some European fashion houses still prefer but the Instagram generation has moved on and like coffin.  Coffins are rare worn in the elongated form.

Square nails provide a shape which is less susceptible to damage than many but doesn’t suit all shapes.  It’s best adopted by those with a narrow nail bed because the flat tip creates an optical illusion of additional width, making nails appear wider than they are.  Rarely seen variations include the cut out (a twin-peaked effect), the lipstick (uniquely, with an asymmetric tip) and the trapeze or flare (where the metaphor is the bell-bottom trouser leg).

A statement shape, something of a triumph of style over functionally, the stiletto gains its dramatic effect from long and slender lines and can be shaped with either fully-tapered or partially square sides.  They’re vulnerable to damage, breaking when subjected to even slight impacts and almost never possible with natural growth.  True obsessives insist they should be worn only with stiletto heels and then only if the colors exactly match.

Squovals in Dior 999.

With straight sides and a curved top, the squoval, while not as dramatic as a coffin, is good, functional engineering because its softer edges are less prone to snagging and tearing than those of a square and break less the more more delicate almonds.  Technically, the squoval is just a species of the square but its popularity meant it came to be classified as its own genus.

Usually very long, the almond has an elongated shape and a tapered tip.  Even when applied to nails with a narrow bed, they’re inherently weak at the tip so most are constructed from acrylics.  It’s a style which attracts many variations on the theme, often tending to a truer emulation of the nut at which point some should probably be classified as pointed.

Realistically, pointed nails, certainly in their more extreme iterations (sometimes called mountain peaks, edges, arrow-heads, claws or talons), are more for short-term effect than anything permanent.  Best used with acrylics, the knife-like style can be a danger to the nail itself and any nearby skin or stockings.  Those contemplating intimacy with a women packing these should first ponder the implications.

Lindsay Lohan with rounds, 2006

Rounds are less a style than a detailing of the natural human shape.  Usually worn short and simple and rarely needing an acrylic overlay, it’s a classic look with the added benefit of durability and low maintenance.

1400-1450:  From the Late Middle English pumpe, cognate with Middle Low German pumpe and Middle Dutch pompe (water conduit, pipe).  Later variations were the Dutch pompen, the German pumpen, and the Danish pompe.  All are thought derived from the Spanish bomba of imitative origin, the source thought to be North Sea sailors, either an imperfect echoic or something imitative of the sound of the plunger in the water.  The earliest use in English was in reference to a device to raise and expel bilge water from ships and the Late Old French pompe probably is from something Germanic.  The mystery is that pumps are ancient machines so the late appearance in the Germanic word is odd in that no evidence has been found of a previous descriptive word.  The use as an "an act of pumping" is attested from the 1670s.  Pump & pumping are nouns & verbs, pumper is a noun, pumpy is a noun & adjective and pumped is a verb & adjective; the noun plural is pumps.

Pump-action, in reference to a type of repeating firearm equipped with a rapid loading mechanism is attested in advertisements from 1912 but it’s unknown whether this was an invention by a manufacturer or retailer or an adoption of existing slang.  The metaphoric extension in pump (someone) for information is from 1630s.  To pump iron as a term for the lifting of weights for fitness was first noted in 1972; pump-classes in gyms became popular in the 1990s although label wasn’t (virtually) universal until circa 2002.  The meaning “low shoe without fasteners" dates from the 1550s and is of unknown origin but was perhaps (very speculatively) echoic of the sound made when walking in them or, more plausibly, from Dutch pampoesje (type of sandal worn in the Dutch East Indies), derived from the Javanese pampoes and ultimately of Arabic origin.  Some sources propose a connection with pomp but it’s undocumented.  The name pump was applied to many shoes with a very low heel, convenient in situations where freedom of movement was required and thus preferred by dancers, couriers, acrobats, duellists and such.  In the shoe business, the definition soon wandered with differences noted between British and North American applications.

The now obsolete nineteenth century phrase “keep your toes in your pump” was dialectal for "stay calm, keep quiet, don't get excited", in the same sense as advice not to “get your knickers in a knot”, the latter which has survived.  In slang, to "be pumped" is (1) to be excited in anticipation of something, (2) having muscles in an engorged state following exercise, (3) in body-building, having muscles which have responded as expected to steroids or other drugs, (4) in rock-climbing, being severely fatigued, (5) in cosmetic surgery & certain non surgical treatments, having a fuller appearance (lips, breasts etc) by virtue of the insertion of implants or an injection of some chemical and (6) among models and other women, the sense of relief upon replacing fetching but uncomfortable shoes with a pair of welcoming and accommodating pumps.

Of pumping ship

Pumps are of great importance on ships because of the need quickly to be able to remove unwanted water from inside a hull.  At sea, when a ship is "taking on water", if pumps fail or the entry of water exceeds pumping capacity, a ship will become unstable and it may sink.  In the smallest vessels, hard-pumps are used while mechanical devices are installed on anything larger than a modest dinghy.  In admiralty jargon, the command “Pump Ship!” is an instruction to begin pumping with all pumps and, in the way sailors adapt such things, it entered naval vernacular as the phrase meaning “I intend to urinate”.

It was picked up by nautical types in civilian life but was probably unknown to most until the publication (in three volumes, 2021-2022) of the unexpurgated diaries of Sir Henry "Chips" Channon (1897–1958), a US born English MP and socialite.  Edited by Dr Simon Heffer (b 1960), the entry of interest was from 19 November 1936 when Channon hosted one of his many glittering dinners in the dining room designed by Parisian interior decorator Stéphane Boudin (1888–1967, his House of Jansen later decorating the White House for Jacqueline Kennedy (1929-1994; US First Lady 1961-1963)) and modelled on the interior of the Amalienburg, an eighteenth century hunting lodge in on the grounds of the Nymphenburg Palace Park outside Munich, a place notorious for the intricacy of its fittings, even by the standards of Rococo.  The Amalienburg was built for someone who would later be Holy Roman Emperor, just the sort of crew with whom Channon identified and he had the elaborate style replicated in the dining room of his London house in Belgrave Square, including even the Bavarian national colors of blue & silver.  Unfortunately, no color photographs appear to have survived and the room was later disassembled, the extendable mirrored table, which could expand to a length of 25 feet (7.7 m), occasionally offered at auction.  By all accounts, the room truly was “breathtaking” and it was one of the few things in life of which Channon could find no grounds for criticism, it living up to his expectation it would “shimmer in blue and silver” and “shock and stagger London”.  For that alone he seemed to think the Stg£6,000 (mostly money he had married) cost (some Stg£525,000 adjusted for 2023) well worth it.  To illustrate the relativities, the next year he would purchase a V12 Rolls-Royce Phantom III for a sum (Stg£1900 for the chassis & another Stg£1100 to have a coach-builder fabricate a body) which would then have bought six houses in a middle-class London suburb although it’s not known if that’s something he’d have known, “middle class” being about the worst thing he could think to say of anyone.

Dining Room, 5 Belgrave Square, London, circa 1937.

On that November evening the guest of honor was King Edward VIII (1894–1972; King of the UK & Emperor of India January-December 1936, subsequently Duke of Windsor) and Channon noted in his diary his surprise at the monarch’s “modern” turn of phrase when he rose and announced “I want to pump shit.”  A dutiful host, Channon recorded he “…led His Majesty to our loulou! He proceeded to pass water without shutting the door, talking to me the while”.  That fragment of royal history was printed in the first volume (2021) of the published diaries (it was a measure of the deference which still applied in the England of 1965 that when first they appeared in heavily redacted form the passage was omitted) but comments soon appeared suggesting neither Channon nor Dr Heffer were well-acquainted with the sailors' slang the king would have learned during his brief naval career.  Dr Heffer responded by examining closely the original entry in the diarist’s hand and concluded the relevant character really was a “t” and not a “p” so the words on the night were either “misheard or misunderstood” and there’s little doubt what was said was “pump ship” and not “pump shit”.  He added that like Channon, he had “no naval connections” and was as thus just as “unfamiliar with the sea-dog slang” but that when the paperback edition was proofed, the text would be changed and an explanatory footnote (the diaries worth reading just for Heffer’s detailed footnotes) added.  Rising to the occasion, he observed this meant the “the hardback edition is destined to become a collector's item.”  The dinner proved the apogee of Channon’s social life because he’d backed the wrong royal horse, Edward VIII abdicating within weeks of having pumped ship in Belgrave Square.

Of Pumps, Courts and Flats

The homogenization of English was well-advanced long before the ubiquity of the internet but well into the twentieth century, different meanings for words could evolve in parallel in different regions of the same country, let alone between different states or provinces.  In British English, a court shoe was a woman’s shoe with a low cut vamp, sometimes with no instep fastening and otherwise adorned with a shoe buckle or a bow as an ostensible fastening.  In US English, such a shoe is a pump; pumps and court shoes may or may not have an ankle strap.  Pumps today, on either side of the Atlantic, are almost exclusively worn by women but historically were also formal shoes for men, the male variation called an opera slipper or patent pump.  For men, the pump gained ascendency over the dress boot as modern road-making techniques rendered cities less muddy places and dress pumps remained the standard for evening full-dress until the Second World War.  They remain the usual choice for black tie events and are obligatory with white-tie; the original design with steel-cut buckles, otherwise long extinct, still part of British court uniform and dress.

The construction of pumps is simple, using a whole-cut leather top with a low vamp, lined with either quilted silk or plain leather, trimmed with braid at the opening. The full leather sole is either glued onto the bottom, common on cheaper styles, or sewn, as on more costly bespoke styles still made traditionally, using a shallow slit to lift a flap of leather around the edge to recess and hide the stitching. The sole is, as on ordinary shoes, several layers of leather put together. The bow is made of grosgrain silk or rayon, in a pinched or flat form.  Pumps, which may have an ankle strap, if also constructed with a strap across the instep, are called Mary Janes.

Most of the UK fashion business adopted the US use of pump because it simplified the mechanics of trade.  Otherwise, in the UK (and most of the Empire and Commonwealth) a pump implied a flat or low-heel ballet slipper or even rubber-soled canvas plimsolls.  Ballet slippers (now more often called flats) date from the medieval period, their popularity declining in only in the seventeenth century when higher heels became fashionable.  After a brief nineteenth century revival, heals again prevailed until the 1960s when they became suddenly and wildly popular after Brigitte Bardot appeared in a pair of Rose Repetto’s hand-stitched ballet flats.  These days, between heals and flats, it seems a draw although the trend increasingly to prefer the comfort of the flat as the years pass is noted.

Except for court dress, historic references or the exact (if not always enforced) rules for white-tie, there’s now less precision attached to the use of pump and the word should be thought of as referencing a range of closed and open-toed shoes, with and without straps, bows or buckles, the other useful modifier being some reference to the height or type of the heel.  This means anything from a modest kitten to an elongated stiletto and, depending on the airport at which one lands, a flat may be a ballet flat or a ballet pump.

In US use, pumps are exclusively women's shoes with a kitten or higher heel; flats are never pumps and Canada, always more influenced by US linguistic imperialism, followed; that influence is now almost universal and the notion of the flat pump, while not extinct, has declined.  Heels for pumps vary, from the kitten 1-2 inch (25-50 mm) to the stripper (200-250 mm), the bulk of stiletto sales in the 3-5 inch (75-125 mm) range.  They can be made from any material though the classic is patent leather and, under rules formalised by Donald Trump's (b 1946; US president 2017-2021) Miss Universe contests, white, stiletto pumps were once obligatory in the swimsuit section of beauty pageants.  Perhaps surprisingly to some, the swimsuits have survived much criticism as have the stilettos although they're no longer exclusively white and, open-toed and strappy, in most places they wouldn't even be thought of as pumps.

Of the Holley Double Pumper

Even in an age when electronic fuel-injection (EFI) has long been the standard form of induction in internal combustion engines, there remain silos in which the now arcane languages of carburetors are spoken and while there is some commonality of terms among the shortcuts, abbreviations & euphemisms of these vernaculars, a trained ear can pick the differences between the flavours to tell which dialect (SU, Weber, Holley, Rochester, Carter et al) is in play.  One part of the Holley tongue is “double pumper”.  A Holley double pumper is a four barrel carburettor with two accelerator pumps (the source of the moniker) and a mechanical linkage connecting the primary and secondary sides of the device.  Widely used during the classic era (1964-1971) of the US muscle cars, the main advantage of the design was the twin accelerator pumps prevented the transitory leanness in the fuel-air mixture which can happen during quick throttle blade movements if only a single pump is fitted.  All multi-barrel carburetors use an accelerator pump circuit but many have only one feeding the primary barrel(s).  These pumps spray a quick shot of the mix to compensate for the split-second lag which will happen before the main circuit fully responds to a throttle pushed suddenly wide open.  All double pumper carburetors use an accelerator pump circuit on both the primary and the secondary sides.

It’s important not to refer to vacuum secondary carburettors (VSC) as any sort of pumper.  A VSC uses a secondary opening controlled by a vacuum diaphragm which opens the secondary barrels only when there is sufficient airflow demand to require it so no accelerator pump is required on the secondary side.  So, a VSC is technically a “single pumper carburettor” but that term is never used and anyone referring to one as such will lose face.  There's also a point of etiquette of which to be aware.  While “VSC” is an accepted term, a double pumper is never referred to as a “DP” because use in the pornography industry has made “DP” exclusively their own and it seems mere politeness not to intrude on their noble linguistic traditions.

There is an (unverified) industry legend that the "double buffer" terminology adopted in 1991 when Microsoft released version 4 of the Smart Drive (smartdrv.exe) disk cache was the coining of a coder who used a Holley double pumper in his muscle car.  That may or may not be true but "double buffer" lives on in the memory management of graphics processing units (GPU) as a description of the temporary storage areas in main memory where data is held during the transfer process.  The trick is that rather than processes being sequential, while program x is being read, program y can be written and vice versa.  It's not exactly quantum mechanics but means things simultaneously are happening in two places; for the gamers for whom GPUs are a fetish, every millisecond matters.
