Proboscis

Proboscis (pronounced proh-bos-is or proh-bos–kis)

(1) A long flexible prehensile trunk or snout, as that of an elephant.

(2) In zoology, any elongated tube from the head or connected to the mouth.

(3) In entomology & malacology, the elongate, protruding mouth parts of certain insects and certain invertebrates like insects, worms and molluscs, adapted for sucking or piercing (more popularly called “the beak”).

(4) Any of various elongate feeding, defensive, or sensory organs of the oral region, as in certain leeches and worms.

(5) In facetious use, the human nose, the use probably roughly with the size of prominence of the nose.

(6) In informal use, as applied in geography, engineering, geometry etc, any protrusion vaguely analogous with the human nose.

1570-1580: From the Latin proboscis (trunk of an elephant), from the Ancient Greek προβοσκίς (proboskís) (elephant's trunk (literally “feeder; means for taking food"), the construct being προ- (pro-) (before) +‎ βόσκω (bóskō) (to nourish, to feed”), from boskesthai (graze, be fed), from the stem bot- (source of botane (grass, fodder) and from which English gained botanic), from the primitive Indo-European root gwehs (source also of βοτάνη (botánē) (grass, fodder) + -is (the noun suffix).  The related terms include nose beak, organ, snoot, snout, trunk and probably dozens of slang forms.  Other descendents from the Latin include the Italian proboscide, the Portuguese probóscide and the Spanish probóscide.  Proboscis & proboscidean are nouns and proboscidate is an adjective; the noun plural is proboscises or proboscides.  The Greek derived form of the plural (proboscides) appears often in the technical literature that built using the conventions of English (proboscises) appears to be the common general form, rare though it is.

Aerodynamics were of interest to some even in the early days of the automobile and those involved in motorsport were more interested than most.  For decades, the interest manifested mostly in the art of streamlining, the reduction of drag and research, accomplished mostly without wind-tunnel testing and obviously without computers, tended to produce cigar-shaped bodies with as few protrusions as possible.  Drag in many cases was certainly minimized, some of the shapes rendered in the 1920s & 1930s delivering drag coefficients (CD) impressive even by twenty-first century standards but it took a long time before fully it was understood that the fluid dynamics (the behavior of air) at the rear of a vehicle could be as significant as the more obvious disturbances at the front.  Not un-related to this was that it also took time (and not a few deaths) before it was appreciated quite how vital was the trade-off between drag-reduction and the downforce needed to ensure cars did not “take-off” from the surface, resulting in instant instability.

The 1923 Benz Tropfenwagen (teardrop vehicle) (left) not only used an aerodynamic nose using lessons learned from military aviation during World War I (1614-1918) but was able to optimize the shape because the engine was mid-mounted, something would wouldn’t become commonplace in Formula One for over thirty years.  The front-engined 1931 Grand Prix Mercedes-Benz SSKL (centre) made few concessions to aerodynamics, relying on power and weight-trimming but when that approach reached its evolutionary dead-end, a streamlined SSKL (1932, right) was crafted, limitations on what could be done with the nose imposed by the bulk and height of the engine.

That the early attempts at streamlining might induce aircraft-like “take-offs” was not surprising given so much of the available data came from work in ballistics and aeronautics where lift is desirable and as speeds rose, it became clear what would need also to be considered was what air was doing underneath the vehicle, some cars obviously with "just enough lift to be a bad airplane" as one driver put it.  That increase in speed in itself imposed a limit on research, the terminal velocities suddenly possible exceeding the capacity of ground-effects based wind tunnels and few manufacturers had access to test facilities with straights of sufficient length to match those on some race-tracks.  High-speed testing was thus sometimes undertaken by racing drivers at speeds rarely before explored, something complicated by being among disrupted air induced by surrounding cars and some unpredictable behavior ensued; it was actually remarkable there weren’t more fatalities than there were.

In the embryonic study of aerodynamics, one of the first conclusions (correctly) drawn was that few changes produced more dramatic improvements than lowering and optimizing the shame of the nose.  At the time, it was something not as simple as it sounded, engines mounted usually close to the nose and in the era, those usually long-stroke engines were tall, often in-line units, a shape which imposed limits on what was possible.  Jaguar used dry-sump lubrication on the D-Type (and the road-going derivative the XKSS) to allow the nose to drop a few inches compared with its predecessor, an expedient also adopted by Mercedes-Benz for their 300 SL (W198, 1954-1957) and 300 SLR (W196S, 1955), more lowering still made possible by mounting the power-plant at an acute angle.

In the same era, Maserati, impressed by the speed of the Mercedes-Benz W196 when fitted with the "streamliner" body used on the faster circuits and, apparently without the benefit of a wind-tunnel, developed its own partially enclosed bodywork for its 250F Grand Prix car but it also developed, quite serendipitously, an even more effective shape and it was initially known as the “long-nose” 250F until it proved so successful it was adopted as the definitive 250F body.

The long and short of it: The Ferrari 250 LM in long (left) and short (right) nose configuration.

Ferrari and others noted the gains aerodynamics provided and among engineers, some fairly inaccurate (though broadly indicative) "rules of thumb" emerged, based usually on the calculation that for every one inch (25 mm) reduction in nose height, an effective gain of so many horsepower would be realized.  Precise or not, the method, honed by slide-rules, lingered until computer calculations and wind tunnels began more accurately to produce the numbers.  Ferrari’s first mid-engined sports car, the 250 LM (1963-1965), was one of the vehicles to benefit from a nose job, the revised bodywork fashioned by coachbuilder Piero Drogo (1926–1973) who had formed the Modena-based Carrozzeria Sports Cars to service the ecosystem of sports cars that congregated in the region.  There was an urban myth the Drogo nose was created so an “FIA standard size” suitcase could be carried (to convince the regulatory body it was a car for road and track rather than a pure racing machine) but it was really was purely for aerodynamic advantage.

Testing confirmed the “Drogo nose” certainly conferred aerodynamic benefits on the 250 LM but the change brought it own difficulties because Ferrari was at the time attempting to convince the Fédération Internationale de l'Automobile (the FIA; the International Automobile Federation) the 250 LM should be homologated in the Grand Turismo (GT) category so it could contest the World Sports Car Championship.  This was being done using the argument the 250 LM was a mere update of the 250 GTO, despite the 250 LM having a different engine & transmission (mid rather than front-mounted) and a different body.  For homologation to be granted, there had to be 100 essentially identical examples of the model produced and given (1) there were such fundamental differences from the earlier 250s and (2) not even two dozen 250 LMs had then been produced, the FIA was understandably reticent.  However, as a gesture of good faith, Ferrari undertook (eventually) to produce the requisite 100 (even displaying what proved to be a one-off road-going version, complete with a plush interior and electric windows, to bolster the claim it belonged in the GT category) and issued a very public recall notice for all 250 LMs to be returned to the factory to be fitted with the Drogo nose.  One 250 LM (chassis 6321) however was by then being raced in Australia which was a long way away so that one was quietly overlooked (the FIA either turned a blind eye or didn't check), meaning that at least for some time it was the only “short-nosed” 250 LM left in the world, although it’s known at least two have since be converted back to their original specification.  Eventually, 32 250 LMs would be built and the FIA didn’t relent, forcing the car to compete in the 1965 championship against much faster machinery in the prototype class but it was fast enough and importantly, more reliable than the more fragile prototypes and chassis 5893 won the 1965 Le Mans 24 hour endurance race, Ferrari's last victory in the event.

Ferrari 275 GTB short (left) and long-nose (right).

The 1960s saw the last generation of Ferrari cars styled without the use of wind tunnels or much in the way of electronic assistance.  Even for the road cars, as speeds rose, some high speed instability was occasionally noted but this became pronounced with the cars were used in competition, especially on the faster tracks with the long straights.  Accordingly, knowing there would be a competition version of the 275 GTB (the 275 GTB/C) a long-nose was created which was also used on other models.  The 275 GTB/C was notable also for marking the swan song of the classic Borrani wire-spooked wheels on Ferrari competition cars, the elegant, chromed creations no longer strong enough to handle the increase loads in extreme conditions, replaced by aluminium or magnesium castings.

1969 Dodge Daytona (left) and 1969 Dodge Charger 500 (right).

Across the Atlantic, on the NASCAR (National Association of Stock Car Auto Racing) circuits, the manufacturers had reached a dead end imposed by their regulatory body.  By 1969 the NASCAR authorities had fine-tuned their rules, restricting engine power and mandating a minimum weight so manufacturers, finding it increasingly harder to cheat, resorted to the then less policed field of aerodynamics, ushering what came to be known as the brief era of the "aero-cars".  Dodge began by making modifications to their Charger which smoothed the air-flow, labelling it the Charger 500 in a nod to the rules which demanded 500 identical models for eligibility.  It proved less successful than hoped and Dodge apparently gave up on the design, producing on 392 (although to make up the numbers they did the next year add an unrelated “500” option to the Charger line and NASCAR generously turned their blind eye).  Not discouraged however, Dodge recruited engineers from Chrysler's soon to be shuttered (as arms control treaties with the USSR loomed) aerospace & missile division and quickly created the Daytona, adding to the 500 a protruding nosecone and high wing at the rear.  Even now, the nosecone would be thought extreme but it worked on the track and this time the required 500 were actually built.  NASCAR responded by again moving the goalposts, requiring manufacturers to build at least one example of each vehicle for each of their dealers before homologation would be granted, something which would demand thousands of cars.  Accepting the challenge, in 1970 Dodge's corporate stablemate Plymouth duly built about two-thousand of their similar aero car, the Road Runner Superbird, an expensive exercise given they reportedly lost money on each one.  Now more unhappy than ever, NASCAR lawyered-up, drafted rules rendering the aero-cars uncompetitive and their brief era ended.  So extreme in appearance were the cars they proved at the time sometimes hard to sell and some were actually converted back to the standard specification to get them out of the showroom.  Views changed over time and they're now much sought by collectors, selling for up to US$500,000 in the most desirable configuration.

As imposing as the noses developed for the Daytona and Superbird were, it may have been that much of the modification was wasted effort and an application of the Europeans’ old “inch by inch” rule of thumb might have been as effective.  The nose jobs Ford in 1969 applied to their Torino Talladega and Mercury’s Cyclone Spoiler II were modest compared to what Chrysler did.  The grill was flattened, a la the Charger 500, the front bumper was replaced with a re-shaped version of the rear unit from a 1969 Fairlane which functioned effectively as an air-dam and the leading edge of the nose was extended and re-shaped dowwards.  The effect was subtle but on the track, appeared to confer a similar advantage to the one Chrysler’s rocket scientists had achieved but Ford had also made some changes which lowered the centre of gravity and improved the under-body air-flow.  Quite what this achieved has never been documented but the drivers were certainly convinced, retaining the Talladegas and Cyclone Spoilers as long as possible, the shapes proving much more efficient than their sleek-looking successors.

Porsche 911 (930) Turbo in profile (left) and Porsche 911 (930) flachbau (slantnose).

When in 1973 regulations forced Porsche to fit more substantial bumpers to the 911 (in production since 1964), it necessitated a change to the front bodywork, the earlier cars became known as the "long hood" and subsequent models the "short hood", both references to the hood (bonnet) being shortened to accommodate the unsightly battering rams.  More nose jobs would follow.  Between 1982-1989, Porsche produced three generations of the 911 (930) Turbo S with the flachbau (slantnose) bodywork, a total of 948 believed built.  It seems there were a few, hand-built prototypes completed by 1980 in addition to one completed under the factory’s Sonderwunsch (Special wishes) programme for an individual who was either well-connected or a very good customer.  The 58 first generation cars lack the pop-up headlamps so associated with the design, instead using smooth, flat-faced wings with a fibreglass front valance assembly containing twin lamps either side below the bumper.  Nicknamed the “hammerhead”, the styling divided opinion and was anyway found not to be compliant with regulations in some markets, thus the substitution of the pop-up headlamps which appeared during 1983.  As was typical of much which emerged from the programme, the cars were built with a variety of Sonderwunsch options so there was no one consistent specification.

1973 Porsche 911 Carrera RS from the long hood era (left) and 1975 Porsche 911 Turbo (930) with the short hood used since the 1974 model year (right).  Such is the lure of the early 911s something of a cottage industry has emerged, devoted to "backdating" later cars.     

The second generation flachbau yielded 204 cars, the styling updated with a simplified air dam containing driving lights and a centrally mounted oil-cooler, the pop-up headlamps relocated to front wings, a much admired feature the optional air-intake vents above the pop-ups, something borrowed from the 935 track cars.  Again, other than the structural changes, there was no standard configuration, each flachbau reflecting the buyer’s ticking of the option list and any special wishes the factory was able to satisfy.  The third generation were the most numerous with 686 produced, the increased volume reflecting the effort made to ensure the cars could be made available in the lucrative US market which eventually received 630 flachbaus.  More standardized, production shifted from the Sonderwunsch’s Restoration and Repair Department facility (Werks 1) to the line in Zuffenhausen where the standard 930s were assembled though for ease of completion (and to maintain exclusivity) the cars were transferred to the Sonderwunsch for finishing and detailing.

Wax model of Thomas Wedders (circa 1730-circa 1782).

Thomas Wedders (AKA Thomas Wadhouse) from Yorkshire, England (a member of a travelling "freak show" circus) is recorded as having enjoyed (sic) the world's longest known human nose, claimed to be some 200mm (7¾ inches) in length.  In the absence of any verified evidence, the truth of that can't be known but it may be assumed his nose was very big.  The current record is held by Mehmet Özyürek (b 1949) of Türkiye, his nose officially measured and found to be 88mm (3½ inches).

Groyne

Groyne (pronounced groin)

A wall or jetty built out from a riverbank or seashore to control erosion; also known as a spur or breakwater, acting as a "strong, low sea wall".  The US spelling is for all purposes: groin.  The noun plural is groynes.

1580s: Origin contested, some sources claim it’s an alteration of groin, the use based on a vague anatomical similarity.  The alternative etymology, this one linked to porcine proboscis anatomy, traces the origin to the Middle English groyn (snout) from the Old French groign & groin (muzzle, snout; promontory, jutting part) from the Late Latin grunium & grunia, derived from the Classical Latin grunnire (grunt like a pig).  It has troubled etymologists because the use of groin in the sense of "pig's snout" from circa 1300 was obsolete long before the 1580s.  All agree however the link of the Latin and French forms to the colloquial English grunter (a pig).

Groynes are fixed hydraulic structure extending either from a costal shoreline or riverbank which interrupt the natural water-flow, thereby limiting the movement of sediment.  Historically, groynes were made from timber or stone but synthetic materials are now also used.  Ocean groynes tend towards being perpendicular to the shore, extending from the upper foreshore or beach into the water where as riparian structures are often laid at more acute angles.  Groynes may be wholly or partially submerged and the space between two is called a groyne field although they’re generally built in a series, often in tandem with seawalls.

English spelling evolved under many influences and this produced anomalies and absurdities, some of which the Americans corrected and it would be nice if the rest of the English-speaking world could be convinced to adopt the more rational of their innovations.  However, like cheque & check, groin (part of a body or vault) & groyne (a breakwater) share one pronunciation yet more than one meaning so maintaining two different spellings seems useful.  It's one of those examples where the often commendable simplification of US English is not helpful.

1400–1450: From the late Middle English tronke & trunke, from the Old French tronc (alms box, tree trunk, headless body), from the Latin truncus (stem, a stock, lopped tree trunk), a noun use of the adjective truncus (lopped; cut off, maimed, mutilated), (the later related to the English truncated).  Trunk & trunking are nouns & verbs, trunkful is a noun, trunked is a verb & adjective and trunkless is an adjective; the noun plural is trunks.

There are a myriad of “truck” terms in human pathology and other derived phrases include “elephant's trunk” (rhyming slang for “drunk”), “hand trunk” (a piece of luggage smaller than the traditional trunk and able to be carried by one), “junk in one's trunk” (corpulence of the buttocks, the alternative forms being “dump truck” or the vernacular “fat ass”), “the apple does not fall far from the trunk” (a variant of “the apple/pear etc does not fall far from the tree”) (children tend in appearance & characteristics to resemble their parents), “trunklid” (literally obviously “the lid of a trunk” and used of the opening panel which provides access to a car’s trunk), “bootlid” the UK equivalent and confusingly in the US used also as “decklid” on the basis of the trunk being a part of a car’s “rear deck”), “trunk novel” (a novel abandoned by the author while still a project), “trunk or treat” (an organized alternative to trick-or-treating where candy is handed out to children from cars in a parking lot; it was introduced as a child safety measure), “trunk show” (an event in which vendors present merchandise directly to store personnel or customers at a retail location or other venue, based on the idea of selling “out of a trunk”), “trunk sale” (and event at which goods are displayed for sale in the trunks of cars), “boot sale” the companion term)), “trunking” (travelling sitting in the trunk of a car”), and “trunk shot” (in film-making, a cinematic shot from within a car trunk (although there was a case of a serial killer who shot his victims while concealed in the trunk of a car.

Louis Vuitton Trunk #5 (left) and Louis Vuitton Trunk on Fire (right) by Tyler Shields (b 1982).

The original idea of a trunk being a “box; case etc” may lie in the first such “trunks” being hollowed-out tree trunks although some suggest the post-classical development of the meaning “box, case with a lid or top” was based on the notion of human body’s trunk being a “case” in which the organs were transported.  The modern idea of a “luggage compartment of a motor vehicle” dates from circa 1930, about the time trunks cease to be something separately carried and replaced by and space for luggage integrated into the bodywork.  The use of trunk had long been familiar in the medical literature (both of the torso and blood vessels etc) and the idea was by 1843 extended to railroad trunk lines and telephone networks by 1889.  “Trunk-hose” were first sold in the 1630s and seems to have been a kind of thermal underwear, the description a reference to them covering the whole torso (ie, the trunk) as opposed to most “hose” which was for the lower limbs.

The use of trunk to describe the “long snout of an elephant (or other beast with a similar appendage)” appeared first in the 1560s but etymologists are divided on whether it was an allusion to a tree’s trunk or has some connection with “trumpet”, based on the loud sound elephants are able to generate although the evidence does suggest the early use as a reference to the thing’s ability to hold water.  Predictably, by the early eighteenth century, it was a slang term for the human nose.  The use in clothing (always in the plural as “trunks”) emerged in the mid 1820s and initially described “short breeches of thin material”; it was a use of trunk in the sense of “torso”.  Use began in theatrical jargon but, as was not uncommon, soon it was applied to breeches generally, especially in US English and for the short, tight-fitting breeches worn by swimmers and other sporting types, adoption was close to universal by the 1890s.  “Swimming trunks” has survived as a regionalism; even within the one country, there are often several different names for what is one of humanity’s most simple garments.

Trump Trunks: MAGA (Make America Great Again) swimming trunks.  Trump trunks are made from a “silky, breathable, 4-way stretch mesh fabric” and features include (1) a small internal pocket, (2) a built-in anti-chafe liner.  The country of manufacture is not disclosed.  Clearly, the DNC (Democratic National Committee) in 2016 missed an opportunity by failing to release the "Crooked Hillary Clinton Bikini".

One linguistic curiosity was “subscriber trunk dialing” (later changed to “subscriber toll dialing” which later still switched to DDD (Direct Distance Dialing).  The “other” use of STD was as “sexually transmitted disease”, previously known as VD (venereal disease) and it wasn’t until the 1970s the initialism VD began to be replaced by STD (VD thought to have to have gained too many specific associations) but fortunately for AT&T, in 1951 they renamed their STD service (for long-distance phone calls) to DDD, apparently for no better reason than the alliterative appeal although it's possible they just wanted to avoid mentioning “toll” with all that implies.  Many countries in the English-speaking world continued to use STD for the phone calls, even after the public health specialists had re-purposed the initialization.  In clinical use, STI “Sexually Transmitted Infection” seems now the preferred term).

The evolution of the trunk: 1851 Concord stagecoach on display at the Smithsonian's National Postal Museum, Washington DC (left) with truck strapped to the back, additional trunks carried on the roof; 1928 Mercedes-Benz Nürburg 460 K Pullman Limousine (W08, centre left) with separate trunk still carried on a rear frame; 1936 Studebaker Dictator 4-door sedan (centre right) with the trunk now an integrated part of the bodywork; The US full-sized cars of the era had most capacious trunks but few could match Leyland Australia's infamous P76 (1973-1975, right) which effortlessly could carry a 44 (imperial) gallon (209 litre) drum.

The compartment which is most located in the rear coachwork of an automobile is used for luggage and historically also the spare tyre a toolkit (neither now not always supplied).  In North American use, this is called a “trunk”, an inheritance from the time when the passengers’ trunks (ie, in the sense of the box-like suitcases) were strapped on to an extension at the back of horse-drawn carriages.  In the early automobiles, the practice continued (often with lined wicker baskets because they were of lightweight construction) and when these were integrated into the bodywork, the space provided continued to be called “the trunk”.  The British called the same thing a “boot”.  In horse-drawn carriages in the UK, a “boot” was a compartment used to store travel essentials, among which (in an age of rutted, poorly maintained roads) included boots, the male passengers sometimes required to push the coach when it became stuck in mud, the frequent inclusion of a “boot box” or “boot locker”, made typically of leather and attached at the rear.  The other suggested origin is the French boute (compartment; box).  The term “boot” thus spread throughout the British Empire although, under the Raj, in India & Ceylon (later Sri Lanka) it became the “dickie”.  That was based on the dicky seat (also as “dickie seat” & “dickey seat” and later more commonly known as the “rumble seat”), an upholstered bench mounted at the rear of a coach, carriage or early motorcar and as the car industry evolved and coachwork became more elaborate, increasingly they folded into the body.  The size varied but generally they were designed to accommodate one or two adults although the photographic evidence suggests they could be used also to seat half-a-dozen or more children.  Why it was called a dicky seat is unknown (the word dates from 1801 and most speculation is in some way related to the English class system) but when fitted on horse-drawn carriages it was always understood to mean “a boot (box or receptacle covered with leather at either end of a coach, the use based on the footwear) with a seat above it for servants”.  Under the Raj, “dickie” was preferred while the colloquial “mother-in-law seat” was at least trans-Atlantic and probably global.

Lindsay Lohan illustrates how there are trunks and there are frunks:  The rear-engined Porsche 911 Carrera (997, 2004-2013) cabriolet (Los Angeles, 2012, right) has a frunk while the front-engined Mercedes-Benz SL 550 (R230, 2001-2011) (Los Angeles, 2009, left) has a trunk.  The R230 range was unusual because of the quirk of the SL 550 (2006-2011), a designation used exclusively in the North American market, the RoW (rest of the world) cars retaining the SL 500 badge even though both used the 5.5 litre (333 cubic inch) V8 (M273).

The Fiat X1/9 (produced by Fiat 1972–1982 and Bertone from 1982–1989, centre) featured both a frunk (left) and a trunk (right.

Most cars built have had the engine mounted in the front, thus most trunks appeared in the rear bodywork.  There have however been cars with engines behind the driver (such things were quite numerous until well into the 1970s) and these usually had a storage compartment at the front (where the engine otherwise would sit, under the hood (bonnet)).  Until the early years of the twentieth century, these seem just to have been called a “trunk” or “boot” but as electric vehicles began to appear in volume “frunk” (the construct being f(ront) + (t)runk) and the less popular “froot” (the construct being fr(ont) + (b)oot)) came into use.  There have been mid-engined cars which have both a trunk and a frunk and those in the diminutive Fiat X1/9 were surprisingly large while others (such as Ferrari's Dino 308 GT4 (1973-1980) & 208 GT4 (1975-1980), both badged as Ferraris after 1976) were of a less generous capacity, the frunk in the Dinos most suited to storing something the size of a topless bikini but it was a genuine four-seater (2+2), something not often attempted with the mid-engined configuration.
