Pre 900: From the Middle English noun nail & nayl, from the Old English nægl and cognate with the Old Frisian neil, the Old Saxon & Old High German nagal, the Dutch nagel, the German Nagel, the Old Norse nagl (fingernail), all of which were from the unattested Germanic naglaz.  As a derivative, it was akin to the Lithuanian nãgas & nagà (hoof), the Old Prussian nage (foot), the Old Church Slavonic noga (leg, foot), (the Serbo-Croatian nòga, the Czech noha, the Polish noga and the Russian nogá, all of which were probably originally a jocular reference to the foot as “a hoof”), the Old Church Slavonic nogŭtĭ, the Tocharian A maku & Tocharian B mekwa (fingernail, claw), all from the unattested North European Indo-European ənogwh-.  It was further akin to the Old Irish ingen, the Welsh ewin and the Breton ivin, from the unattested Celtic gwhīnā, the Latin unguis (fingernail, claw), from the unattested Italo-Celtic əngwhi-;the Greek ónyx (stem onych-), the Sanskrit ághri- (foot), from the unattested ághli-; the Armenian ełungn from the unattested onogwh-;the Middle English verbs naile, nail & nayle, the Old English næglian and cognate with the Old Saxon neglian, the Old High German negilen, the Old Norse negla, from the unattested Germanic nagl-janan (the Gothic was ganagljan).  The ultimate source was the primitive Indo-European h₃nog- (nail) and the use to describe the metal fastener was from the Middle English naylen, from the Old English næġlan & nægl (fingernail (handnægl)) & negel (tapering metal pin), from the Proto-Germanic naglaz (source also of Old Norse nagl (fingernail) & nagli (metal nail).  Nail is a noun & verb, nailernailless & naillike are adjectives, renail is a verbs, nailing is a noun & vern and nailed is a verb & adjective; the noun plural is nails.

Nail is modified or used as a modifier in literally dozens of examples including finger-nail, toe-nail, nail-brush, nail-file, rusty-nail, garden-nail, nail-fungus, nail-gun & frost-nail.  In idiomatic use, a “nail in one's coffin” is a experience or event that tends to shorten life or hasten the end of something (applied retrospectively (ie post-mortem) it’s usually in the form “final nail in the coffin”.  To be “hard as nails” is either to be “in a robust physical state” or “lacking in human feelings or without sentiment”. To “nail one's colors to the mast” is to declare one’s position on something.  Something described as “better than a poke in the eye with a rusty nail” is a thing, which while not ideal, is not wholly undesirable or without charm.  In financial matters (of payments), to be “on the nail” is to “pay at once”, often in the form “pay on the nail”.  To “nail something down” is to finalize it. To have “nailed it” is “to perfectly have accomplished something” while “nailed her” indicates “having enjoyed sexual intercourse with her”.  The “right” in the phrase “hit the nail right on the head” is a more recent addition, all known instances of use prior to 1700 being “hit the nail on the head” and the elegant original is much preferred.  It’s used to mean “correctly identify something or exactly to arrive at the correct answer”.  Interestingly, the Oxford English Dictionary (OED) notes there is no documentary evidence that the phrase comes from “nail” in the sense of the ting hit by a hammer.

Double-headed nails.

Double-headed nails are used for temporary structures like fencing.  When the shaft is hammered in to the point where the surface of the lower head is flat against the surface of that into which it's being hammered, it leaves the upper head standing proud with just enough of the shaft exposed to allow a claw-hammer to be used to extract nail.  There is a story that as part of an environmental protest against the building or demolition of some structure (the tales vary), activists early one morning went to the temporary fencing around the contested site and hammered in all the double-headed nails.  This is believed to be an urban myth.

The sense of “fingernail” appears to be the original which makes sense give there were fingernails before there were spikes (of metal or any other material) used to build stuff.  The verb nail was from the Old English næglian (to fix or fasten (something) onto (something else) with nails), from the Proto-Germanic ganaglijan (the source also of the Old Saxon neglian, the Old Norse negla, the Old High German negilen, the German nageln and the Gothic ganagljan (to nail), all developed from the root of the nouns.  The colloquial meaning “secure, succeed in catching or getting hold of (someone or something)” was in use by at least the 1760; hence (hence the law enforcement slang meaning “to effect an arrest”, noted since the 1930s.  The meaning “to succeed in hitting” dates from 1886 while the phrase “to nail down” (to fix in place with nails) was first recorded in the 1660s.

As a noun, “nail-biter” (worrisome or suspenseful event), perhaps surprisingly, seems not to have been in common use until 1999 an it’s applied to things from life-threatening situations to watching close sporting contests.  The idea of nail-biting as a sign of anxiety has been in various forms of literature since the 1570s, the noun nail-biting noted since 1805 and as a noun it was since the mid-nineteenth century applied to those individuals who “habitually or compulsively bit their fingernails” although this seems to have been purely literal rather than something figurative of a mental state.  Now, a “nail-biter” is one who is “habitually worried or apprehensive” and they’re often said to be “chewing the ends of their fingernails” and in political use, a “nail biter” is a criticism somewhat less cutting than “bed-wetter”.  The condition of compulsive nail-biting is the noun onychophagia, the construct being onycho- (a creation of the international scientific vocabulary), reflecting a New Latin combining form, from the Ancient Greek ὄνυξ (ónux) (claw, nail, hoof, talon) +‎ -phagia (eating, biting or swallowing), from the Ancient Greek -φαγία (-phagía).  A related form was -φαγος (-phagos) (eater), the suffix corresponding to φαγεῖν (phageîn) (to eat), the infinitive of ἔφαγον (éphagon) (I eat), which serves as aorist (essentially a compensator for sense-shifts) (for the defective verb ἐσθίω (esthíō) (I eat).  Bitter-tasting nail-polish is available for those who wish to cure themselves.  Nail-polish as a product dates from the 1880s and was originally literally a clear substance designed to give the finger or toe-nails a varnish like finish upon being buffed.  By 1884, it was being sold as “liquid nail varnish” including shads of black, pink and red although surviving depictions in art suggests men and women in various cultures have for thousands of years been coloring their nails.  Nail-files (small, flat, single-cut file for trimming the fingernails) seem first to have been sold in 1819 and nail-clippers (hand-tool used to trim the fingernails and toenails) in 1890.

The expression "nail down the lid" is a reference to the lid of a coffin (casket), the implication being one wants to make doubly certain anyone within can't possible "return from the dead".  The noun doornail (also door-nail) (large-headed nail used for studding batten doors for strength or ornament) emerged in the late fourteenth century and was often used of many large, thick nails with a large head, not necessarily those used only in doors.  The figurative expression “dead as a doornail” seems to be as old as the piece of hardware and use soon extended to “dumb as a doornail” and “deaf as a doornail).  The noun hangnail (also hang-nail) is a awful as it sounds and describes a “sore strip of partially detached flesh at the side of a nail of the finger or toe” and appears in seventeenth century texts although few etymologists appear to doubt it’s considerably older and probably a folk etymology and sense alteration of the Middle English agnail & angnail (corn on the foot), from the Old English agnail & angnail.  The origin is likely to have been literally the “painful spike” in the flesh when suffering the condition.  The first element was the Proto-Germanic ang- (compressed, hard, painful), from the primitive Indo-European root angh- (tight, painfully constricted, painful); the second the Old English nægl (spike), one of the influences on “nail”.  The noun hobnail was a “short, thick nail with a large head” which dates from the 1590s, the first element probably identical with hob (rounded peg or pin used as a mark or target in games (noted since the 1580s)) of unknown origin.  Because hobnails were hammered into the leather soles of heavy boots and shoes, “hobnail” came in the seventeenth century to be used of “a rustic person” though it was though less offensive than forms like “yokel”.

Nails and pins

Mug shot “pin” from TeePublic featuring Lindsay Lohan (b 1986, left), Donald Trump (b 1946; POTUS 2017-2021 and since 2025) and Paris Hilton (b 1981, right).  In this context, although the product really is “the badge”, the name was gained from the built-in pin supplied to secure the object to clothing.

As designs, a nail and a pin are similar, obviously differing only in scale but the function of each is different.  A nail’s primary purpose is to function as a structural fastener joining materials (most typically two or more pieces of wood) although there are specialized nails driven into substrate by impact (variously with hammers or nail guns (sometimes called “pin-nailers”, some of which are built to fire “panel pins” (very slender nails) or small “headless nails”).  A nail relies on friction and compression in the surrounding material for its holding strength.  Pins look like scaled-down nails but mostly are used for alignment, retention or pivoting, rather than structural load-bearing.  Because of their more delicate construction, pins often are inserted through specific-purpose, pre-existing holes and in many cases are intended to be temporary and are thus removable.  Visually, both nails and pins have heads (round, flat, clipped etc) and a tapered shank with a tip pointed for pointed tip for penetration (“snub-nosed” nails do exist but are rare) and both are designed slightly to deform the surrounding material when driven.  The most obvious difference is that a pin’s head is very small and some are spherical and made from plastic; they’re designed only to be pushed with finger-pressure rather than being hit with a hammer.  Although the term “pin” is used for some specialized devices used in building and engineering (dowel pin, pivot pin, gudgeon pin (also as wrist pin), roll pin, cotter pin etc), the word is most associated with the tailor’s pin (used mostly in textiles and usually clipped to “pin”).  In jewelry design and textiles there are also variants including the “lapel pin” and the fashion industry’s device of last resort, the “safety pin”.

Pinhead in publicity shot for Hellraiser III: Hell on Earth (1992).

Clive Barker's (b 1952) supernatural horror movie Hellraiser (1987) was based on his novella The Hellbound Heart (1986) and was a surprise hit, making it a franchise which has thus far spawned nine sequels, the most recent released in 2022.  The plot involved a mysterious puzzle box that, when opened, summoned the Cenobites, a group of extra-dimensional, sadomasochistic beings unable to differentiate between pain and pleasure.  It was a good premise for a horror movie but the character who really captured the audience's imagination was the unnamed figure viewers dubbed “Pinhead”.  Although Pinhead appeared in the original film for fewer than ten minutes, the character became the franchise’s focal point and has since dominated the publicity material for subsequent releases.  The popularity of Hellraiser has been maintained and it’s hoped that for the next release the producers will offer the part to Peter Dutton (b 1970; leader of the Liberal Party of Australia 2022-2025).

Peter Dutton captured by a photographer during a happy moment (left), Pinhead with the box able to summon the Cenobites (centre) and and artist's depiction of Mr Dutton in “Pinhead mode” (digitally altered image, right).

No longer burdened with tiresome parliamentary duties since losing his seat in the 2025 Australian general election, Mr Dutton has time for a third career and he should be good at playing an unsmiling character who speaks in a relentless monotone; really, all he need do is act naturally.  It’s suspected also he’ll be good at learning a script given the decades he spent parroting “talking points” and TWS (three word slogans).  While it’s an urban myth Mr Dutton wasn’t offered the part of Lord Voldemort in the Harry Potter movie franchise because he was deemed “too scary”, as Pinhead he’d be “just scary enough”.  While the LNP (Liberal National Party) state government in Queensland recently has appointed Mr Dutton to the board of the QIC (Queensland Investment Corporation, the investment manager of the state’s Aus$135 billion in assets), it’s understood his duties in the Aus$130,000 per annum role will be neither onerous or time-consuming so there’ll be ample opportunity for film-shoots.  Although when in opposition the LNP had decried the ALP (Australian Labor Party) government’s frequent appointment of ALP figures to lucrative sinecures, once in office the LNP continued the “jobs for the boys” tradition.  In the modern era, the two most striking characteristics of right-wing fanatics is (1) a fondness for sitting safely in a bunker while advocating for (and sometimes sending) other people's children to go a fight a war somewhere and (2) after a career spent extolling the virtues of “private enterprise” and criticizing “government waste”, being anxious to get back on the public payroll as soon as their political careers end.  Reassuringly for taxpayers who may have been worried Mr Dutton would not be able to continue to enjoy the lifestyle to which their taxes made him accustomed (“entitled” as he might have put it), it’s believed his director’s fees from QIC will not affect his parliamentary pension (understood to be between Aus$260,000-Aus$280,000 per annum).

The Buick Nailhead

In the 1930s, the straight-8 became a favorite for manufacturers of luxury cars, attracted by its ease of manufacture (components and assembly-line tooling able to be shared with those used to produce a straight-6), the mechanical smoothness inherent in the layout and the ease of maintenance afforded by the long, narrow configuration, ancillary components readily accessible.  However, the limitations were the relatively slow engine speeds imposed by the need to restrict the “crankshaft flex” and the height of the units, a product of the long strokes used to gain the required displacement.  By the 1950s, it was clear the future lay in big-bore, overhead valve V8s although the Mercedes-Benz engineers, unable to forget the glory days of the 1930s when the straight-eight W125s built for the Grand Prix circuits generated power and speed Formula One wouldn’t see until the 1980s, noted the relatively small 2.5 litre (153 cubic inch) displacement limit for 1954 and conjured up a final fling for the layout.  Used in both Formula One as the W196R and in sports car racing as the W196S (better remembered as the 300 SLR) the new 2.5 & 3.0 litre (183 cubic inch) straight-8s, unlike their pre-war predecessors, solved the issue of crankshaft flex (the W196's redline was 9500 compared with the W125's 5800) by locating the power take-off at the centre, adding mechanical fuel-injection and a desmodromic valve train to make the things an exotic cocktail of ancient & modern (on smooth racetracks and in the hands of skilled drivers, the swing axles at the back not the liability they might sound).  Dominant during 1954-1955 in both Formula One & the World Sports Car Championship, they were the last of the straight-8s in top-line competition.

Schematic of Buick “Nailhead” V8, 1953-1966.

Across the Atlantic, the US manufacturers also abandoned their straight-8s.  Buick introduced their overhead valve (OHV) V8 in 1953 but, being much wider than before, the new engine had to be slimmed somewhere to fit between the existing inner-fenders (it would not be until later the platform was widened).  To achieve this, the engineers narrowed the cylinder heads, compelling both a conical (the so-called “pent-roof”) combustion chamber and an arrangement in which the sixteen valves pointed directly upwards on the intake side, something which not only demanded an unusual pushrod & rocker mechanism but also limited the size of the valves.  So, the valves had to be tall and narrow and, with some resemblance to nails, they picked up the nickname “nail valves”, morphing eventually to “nailhead” as a description of the whole engine.  The valve placement and angle certainly benefited the intake side but the geometry compromised the flow of exhaust gases which were compelled by their anyway small ports to make a turn of almost 180^o on their way to the tailpipe.  As an indication of the heat-soak generated by that 180^o turn, the surrounding water passages were very wide. 

It wasn't the last time the head design of a Detroit V8 would be dictated by considerations of width.  When Chrysler in 1964 introduced the 273 cubic inch (4.5 litre) V8 as the first of its LA-Series (that would begat the later 318 (5.2), 340 (5.5) & 360 (5.9) as well as the V10 made famous in the Dodge Viper), the most obvious visual difference from the earlier A-Series V8s was the noticeably smaller cylinder heads.  The A engines used as skew-type valve arrangement in which the exhaust valve was parallel to the bore with the intake valve tipped toward the intake manifold (the classic polyspherical chamber).  For the LA, Chrysler rendered all the valves tipped to the intake manifold and in-line (as viewed from the front), the industry’s standard approach to a wedge combustion chamber.  The reason for the change was that the decision had been taken to offer the compact Valiant with a V8 but it was a car which had been designed to accommodate only a straight-six and the wide-shouldered polyspheric head A-Series V8s simply wouldn’t fit.  So, essentially, wedge-heads were bolted atop the old A-Series block but the “L” in LA stood for light and the engineers wanted something genuinely lighter for the compact (in contemporary US terms) Valiant.  Accordingly, in addition to the reduced size of the heads and intake manifold, a new casting process was developed for the block (the biggest, heaviest part of an engine) which made possible thinner walls.  "Light" is however a relative term and the LA series was notably larger and heavier than Ford's "Windsor" V8 (1961-2000) which was the exemplar of the "thin-wall" technique.  This was confirmed in 1967 when, after taking control of Rootes Group, Chrysler had intended to continue production of the Sunbeam Tiger, by then powered by the Ford Windsor 289 (4.7 litre) but with Chrysler’s 273 LA V8 substituted.  Unfortunately, while 4.7 Ford litres filled it to the brim, 4.4 Chrysler litres overflowed; the Windsor truly was compact.  Allowing it to remain in production until the stock of already purchased Ford engines had been exhausted, Chrysler instead changed the advertising from emphasizing the “…mighty Ford V8 power plant” to the vaguely ambiguous “…an American V-8 power train”.

322 cubic inch Nailhead in 1953 Buick Skylark convertible (left) and 425 cubic inch Nailhead in 1966 Buick Riviera GS (with dual-quad MZ package, right).  Note the “Wildcat 465” label on the air cleaner, a reference to the claimed torque rating, something most unusual, most manufacturers using the space to advertise horsepower or cubic inch displacement (CID).

The nailhead wasn’t ideal for producing top-end power but the design did generate prodigious low-end torque, something much appreciated by Buick's previous generation of buyers who much had relished the low-speed responsiveness of the famously smooth straight-8.  However, like everybody else, Buick hadn’t anticipated that as the 1950s unfolded, the industry would engage in a “power race”, something to which the free-breathing Cadillac V8s and Chrysler’s Hemis were well-suited.  For that, the somewhat strangulated Buick Nailhead was not at all suited and to gain power the engineers were compelled to add high-lift, long-duration camshafts which enabled the then magic 300 HP (horsepower) number to be achieved but at the expense of smoothness; tales of Buick buyers (long accustomed to straight-8s that ran so smoothly at idle it could be hard to tell if the things were running) returning to the dealer to fix the “rumpity-rump” became legion.  Still, the Nailhead was robust, relatively light and offered what was then a generous displacement and the ever inventive hot-rod community soon worked out the path to power was to use forced induction and invert the valve use, the supercharger blowing the fuel-air mix into the combustion chambers through the exhaust ports while the exhaust gases were evacuated through the larger intake ports.  Thus, for a while, the Nailhead enjoyed a role as a niche player although the arrival in the mid 1950s of the much more tuneable Chevrolet V8s ended the vogue for all but a few devotees who continued use well into the 1960s.  Buick acknowledged reality and, unusually, instead of following the industry trend and drawing attention to displacement & power, publicized their big torque numbers, confusing some (though probably not Buick buyers who were a loyal crew who sometimes would look down on more expensive Cadillacs because they were "flashy").  The unique appearance of the old Nailhead retains some nostalgic appeal for the modern hot-rod community and they do sometimes appear, a welcome change from the more typical small-block Fords or Chevrolets.

Lockheed SR-71 Blackbird (1964-1999).

Not confused about numbers was the USAF (United States Air Force) which was much interested in power for its aircraft but also had a special need for torque on the tarmac and briefly that meant another quirky niche for the Nailhead.  The Lockheed SR-71 Blackbird (1964-1979) was a long-range, high-altitude supersonic (Mach 3+) aircraft used by the USAF for reconnaissance between 1966-1998 and by the NASA (National Aeronautics & Space Administration) for observation missions as late as 1999.  Something of a high-water mark among the extraordinary advances made in aeronautics and materials construction during the Cold War, the SR-71 used Pratt & Whitney J58 turbojet engines which featured an innovative, secondary air-injection system for the afterburner, permitting additional thrust at high speed.  The SR-71 still holds a number of altitude and speed records and Lockheed’s SR-72, a hypersonic unmanned aerial vehicle (UAV) is said to be in an “advanced stage” of design and construction although whether any test flights will be conducted before 2030 remains unclear, the challenges of sustaining in the atmosphere velocities as high as Mach 6+ onerous given the heat generated and stresses imposed by the the fluid dynamics of air at high speed.

At the time, the SR-71 was the most exotic aircraft on the planet but during testing and early in its career, just for the engines to start it relied on a pair of even then technologically bankrupt Buick Nailhead V8s.  These were mounted in a towed cart and were effectively the turbojet’s starter motor, a concept developed in the 1930s as a work-around for the technology gap which emerged as the V12 aero-engines became too big to start by hand but lacked on-board electrical systems to trigger ignition.  The two Nailheads were connected by gears to a single, vertical drive shaft which ran the jet up to the critical speed at which ignition became self-sustaining.  The engineers chose the Nailheads after comparing them to other large displacement V8s, the aspect of the Buicks which most appealed being the torque generated at relatively low engine speeds, a characteristic ideal for driving an output shaft, torque best visualized as a "twisting" force.  After the Nailhead was retired in 1966, later carts used Chevrolet big-block V8s but in 1969 a pneumatic start system was added to the infrastructure of the USAF bases from which the SR-71s most frequently operated, the sixteen-cylinder carts relegated to secondary fields the planes rarely used.

Pre-1000: From the Middle English forke (digging fork), from the Old English force & forca (pitchfork, forked instrument, forked weapon; forked instrument used to torture), from the Proto-West Germanic furkō (fork), from the Latin furca (pitchfork, forked stake; gallows, beam, stake, support post, yoke) of uncertain origin. The Middle English was later reinforced by the Anglo-Norman & Old Northern French forque (it was from the Old French forche which French gained fourche), also from the Latin.  It was cognate with the Old Frisian forke, the North Frisian forck (fork), the Dutch vork (fork), the Danish vork (fork) and the German Forke (pitchfork).  The evolved Middle English form displaced the native Old English gafol, ġeafel & ġeafle (fork) (and the apparently regionally specific forcel (pitchfork) though the use from circa 1200 to mean “forked stake or post used as a prop when erecting a gallows” did for a while endure, probably because of the long-life of the architectural plans for a structure which demanded no change or functional improvement.  The alternative spelling forcque is used in mining and describes the "bottom of a sump".  Perhaps surprisingly, dictionaries don't list forkish or forkesque as standard adjectives.  Fork is a noun & verb, forking is a noun, verb, adjective & adverb, forklike is an adjective and forked is a verb & adjective; the noun plural is forks.

The forks of The Latin furca (in its primary sense of “fork”) may be from the primitive Indo-European gherk & gherg (fork) although etymologists have never traced any explanation for the addition of the -c-, something which remains mysterious even if the word was influenced by the Proto-Germanic furkaz & firkalaz (stake, stick, pole, post) which was from the primitive Indo-European perg- (pole, post).  If such a link existed, it would relate the word to the Old English forclas pl (bolt), the Old Saxon ferkal (lock, bolt, bar), the Old Norse forkr (pole, staff, stick), the Norwegian fork (stick, bat) and the Swedish fork (pole).  The descendants in other languages include the Sranan Tongo forku, the Dutch vork, the Japanese フォーク (fōku), the Danish korf, the Kannada ಫೋರ್ಕ್ (phōrk), the Korean 포크 (pokeu), the Maori paoka, the Tamil போர்க் (pōrk) and the Telugu ఫోర్క్ (phōrk).  In many languages, the previous form was retained for most purposes while the English fork was adopted in the context of software development.

Although visitors from Western Europe discovered the novelty of the table fork in Constantinople as early as the eleventh century, the civilizing influence from Byzantium seems not routinely to have appeared on the tables of the English nobility until the 1400s and the evidence suggests it didn’t come into common use before the early seventeenth century.  The critical moment is said to have come in 1601 when the celebrated traveller and writer Thomas Coryat (or Coryate) (circa 1577–1617) returned to London from one of his tours, bringing with him the then almost unknown "table fork" which he'd seen used in Italy.  This "continental affectation" made him the subject of mirth and playwrights dubbed him "the fork-carrying traveller" while the street was earthier, the nickname "Furcifer" (from the Latin meaning "fork-bearer, rascal") soon adopted and despite the early scepticism, there soon were many types of "specific purpose forks (cake fork, cocktail fork, dessert fork etc).  Mr Coryat thus made one of the great contributions to the niceties of life, his other being the introduction to the  English language of the word "umbrella", another influence from Italy.

Cause and effect: The fork in the road.

In Lewis Carroll’s (1832–1898, the (pen name of Charles Lutwidge Dodgson (1832–1898)) Alice's Adventures in Wonderland (1865), when Alice comes to a fork in the road, she encounters the Cheshire Cat sitting in a tree:

Alice: “Would you tell me, please, which way I ought to go from here?”

Cat: “That depends a good deal on where you want to get to.”

Alice: “I don’t know.”

Cat: “Then it doesn't matter which way you go.”

One can see the cat’s point and a reductionist like Donald Rumsfeld (1932–2021: US defense secretary 1975-1977 & 2001-2006) there would have ended the exchange but the feline proved more helpful, telling Alice she’ll see the Mad Hatter and the March Hare if she goes in certain directions, implying that no matter which path she chooses, she’ll encounter strange characters.  That she did and the book is one of the most enjoyable flights of whimsy in English.

The idiomatic phrase “fork in the road” wasn’t in use early in the seventeenth century when translators were laboring to create the King James Bible (KJV, 1611) so “…the king of Babylon so stood at the parting of the way, at the head of the two ways…” appeared whereas by 1982 when the New King James Version (NKJV, 1982) was released, that term would have been archaic so the translation was rendered as “…the king of Babylon stands at the parting of the road, at the fork of the two roads…”.

Ezekiel 21:19-23; King James Version of the Bible (KJV, 1611):

Also, thou son of man, appoint thee two ways, that the sword of the king of Babylon may come: both twain shall come forth out of one land: and choose thou a place, choose it at the head of the way to the city. Appoint a way, that the sword may come to Rabbath of the Ammonites, and to Judah in Jerusalem the defenced. For the king of Babylon stood at the parting of the way, at the head of the two ways, to use divination: he made his arrows bright, he consulted with images, he looked in the liver. At his right hand was the divination for Jerusalem, to appoint captains, to open the mouth in the slaughter, to lift up the voice with shouting, to appoint battering rams against the gates, to cast a mount, and to build a fort. And it shall be unto them as a false divination in their sight, to them that have sworn oaths: but he will call to remembrance the iniquity, that they may be taken.

Ezekiel 21:19-23; New King James Version of the Bible (NKJV, 1982):

And son of man, appoint for yourself two ways for the sword of the king of Babylon to go; both of them shall go from the same land. Make a sign; put it at the head of the road to the city. Appoint a road for the sword to go to Rabbah of the Ammonites, and to Judah, into fortified Jerusalem. For the king of Babylon stands at the parting of the road, at the fork of the two roads, to use divination: he shakes the arrows, he consults the images, he looks at the liver. In his right hand is the divination for Jerusalem: to set up battering rams, to call for a slaughter, to lift the voice with shouting, to set battering rams against the gates, to heap up a siege mound, and to build a wall. And it will be to them like a false divination in the eyes of those who have sworn oaths with them; but he will bring their iniquity to remembrance, that they may be taken.

The KJV & NKJV closely are related but do in detail differ in the language used, the objective of the latter being to enhance readability while retaining the stylistic beauty and literary structure of the original.  Most obviously, the NKJV abandoned the use of archaic words and convention of grammar (thee, thou, ye, thy, thine, doeth, speaketh etc) which can make it difficult for modern readers to understand, rather as students can struggle with Shakespeare’s text, something not helped by lecturers reminding them of its beauty, a quality which often escapes the young.  The NKJV emerged from a reaction to some of the twentieth century translations which traditionalist readers thought had “descended” too far into everyday language; it was thus a compromise between greater readability and a preservation of the original tone.  Both the KJV & NKJV primarily used the Textus Receptus (received text) for the New Testament and Masoretic Text for the Old Testament and this approach differed from other modern translations (such as the New International Version (NIV, 1978) & English Standard Version (ESV, which 2001) used a wider sub-set of manuscripts, including older ones like the Alexandrian texts (Codex Vaticanus, Sinaiticus etc)  So, the NKJV is more “traditional” than modern translations but not as old-fashioned as the KJV and helpfully, unlike the KJV which provided hardly any footnotes about textual variants, the NKJV was generous, showing where differences existed between the major manuscript traditions (Textus Receptus, Alexandrian & Byzantine), a welcome layer of transparency but importantly, both used a formal equivalence (word-for-word) approach which put a premium on direct translation over paraphrasing, the latter technique much criticized in the later translations.

Historians of food note word seems first to have appeared in this context of eating utensils in an inventory of household goods from 1430 and they suggest, because their influence in culinary matters was strongest, it was probably from the Old North French forque.  It came to be applied to rivers from 1753 and of roads by 1839.  The use in bicycle design began in 1871 and this was adopted directly within twenty years when the first motorcycles appeared.  The chess move was first so-described in the 1650s while the old slang, forks "the two forefingers" was from 1812 and endures to this day as “the fork”.  In the world of cryptocurrencies, fork has been adopted with fetish-like enthusiasm to refer to (1) a split in the blockchain resulting from protocol disagreements, or (2) a branch of the blockchain resulting from such a split.

The verb dates from the early fourteenth century in the sense of (1) “to divide in branches, go separate ways" & (2) "disagree, be inconsistent", both derived from the noun.  The transitive meaning "raise or pitch with a fork" is from 1812, used most frequently in the forms forked & forking while the slang verb phrase “fork (something) over” is from 1839 while “fork out” (give over) is from 1831).  The now obsolete legal slang “forking” in the forensic sense of a "disagreement among witnesses" dates from the turn of the fifteenth century.  The noun forkful was an agricultural term from the 1640s while the specialized fourchette (in reference to anatomical structures, from French fourchette (diminutive of fourche (a fork)) was from 1754.  The noun pitchfork (fork for lifting and pitching hay etc.) described the long-used implement constructed commonly with a long handle and two or three prongs first in the mid fourteenth century, altered (by the influence of pichen (to throw, thrust), from the early thirteenth century Middle English pic-forken, from pik (source of pike).  The verb use meaning "to lift or throw with a pitchfork," is noted from 1837.  The spork, an eating utensil which was fashioned by making several long indents in the bowl to create prongs debuted in 1909.

Dining room of Huis Doorn.

Huis Doorn (Doorn House) near Utrecht in the Netherlands, was the country house in which the exiled Kaiser Wilhelm II (1859–1941; Emperor of Germany & King of Prussia 1888-1918) would live until his death.  Confiscated by the state at the end of World War II (1939-1945), Huis Doorn is now a museum, maintained much as the former Kaiser left it.  At his place on the dining room table sits one of his special forks with three tines, the widened one to the left a blade serving as a knife because a congenitally withered left-arm made the use of a conventional utensil too difficult.

Compelled by circumstances to abdicate at the end of World War I (1914-1918) Wilhelm was granted asylum by the neutral Netherlands, the cabinet insisting his status would be that of a private German citizen; to the status-conscious former Kaiser, it remained for the rest of his life a disappointment that Wilhelmina (1880–1962; Queen of the Netherlands 1890-1948) would neither receive nor visit him.  He’d arrived in the Netherlands accompanied by a reputed 64 train carriages of imperial household goods (furnishings, art, bibelots and such) and an unknown slice of the German exchequer so was able to purchase and adequately decorate Huis Doorn which he purchased, taking up residence in May 1920.  However much of the Imperial Treasury came with him remains a matter of speculation but until his death, he maintained a household staff sufficient to ensure “a certain grandeur”.  Hermann Göring (1893–1946; leading Nazi 1922-1945, Hitler's designated successor & Reichsmarschall 1940-1945) did on several occasions pay a visit but that stopped as soon as the Nazis took power in Germany in 1933; the former sovereign had out-lived any potential usefulness to the party.  Indeed, Adolf Hitler (1889-1945; Führer (leader) and German head of government 1933-1945 & head of state 1934-1945) would have preferred if the old man had had the decency quietly to drop dead because the last thing he wanted was any possibility the monarchy might be restored.  He regarded Benito Mussolini’s (1883-1945; Duce (leader) & Prime-Minister of Italy 1922-1943) greatest mistake (and there were a few) as having not deposed the Victor Emmanuel III (1869–1947; King of Italy 1900-1946) when he had the chance and to his dying day suspected a conspiracy between the Freemasons and the royal court was behind the Duce’s downfall in 1943.  There may be something in that because Marshal Pietro Badoglio (1871–1956; Prime Minister of Italy 1943-1944), appointed by the King as Mussolini’s replacement, was a confessed Freemason.

Speciale vork voor Willem II: One of Wilhelm's silver Kaisergabels (Imperial fork).

In a coda which would have amused those who remembered Winston Churchill’s (1875-1965; UK prime-minister 1940-1945 & 1951-1955) glee at hearing the chant “Hang the Kaiser!” at the end of World War I, after the Netherlands was invaded in 1940, fearing the Nazis might murder their former ruler, through diplomatic channels he offered to receive Wilhelm “with dignity and consideration” if he chose to seek refuge in the UK.  The offer was declined and he remained safely in Huis Doon until his death, the Nazis simply ignoring him because in the euphoria of victory, there was in Germany no longer a significant pro-monarchist movement.  Churchill's offer has been treated by some historians as “a humanitarian gesture” but he always had a fondness for monarchical government (his wife called him “the last man in Europe still to believe in the divine right of kings”) and it's suspected he may have pondered the idea of a restoration (possibly Crown Prince Wilhelm (1882–1951)) in constitutional form.

Der Gableschwanz Teufl: The Lockheed P-38 Lightning (1939-1945).  During World War II, the Luftwaffe’s (German air force) military slang for the twin-boomed Lockheed P-38 Lightning was Der Gableschwanz Teufl (the fork-tailed devil).

Novelty nail-art by US restaurant chain Denny's.  The manicure uses as a base a clean, white coat of lacquer, to which was added miniature plastic utensils, the index finger a fork, the middle finger a knife, the ring finger a spoon, and the pinky finger presumably a toothpick or it could be something more kinky.

The idiomatic “speak with forked tongue” to indicate duplicitous speech dates from 1885 and was an invention of US English though reputedly influenced by phrases settlers learned in their interactions with first nations peoples (then called “Red Indians”).  The earlier “double tongue” (a la “two-faced”) in the same sense was from the fifteenth century.  Fork as a clipping of the already truncated fork-lift (1953) fom the fork-lift truck (1946), appears to have enter the vernacular circa 1994.  The adjective forked (branched or divided in two parts) was the past-participle adjective from the verb and came into use early in the fourteenth century.  It was applied to roads in the 1520s and more generally within thirty years while the use in the sixteenth and seventeenth century with a suggestion of "cuckold" (on the notion of "horned") is long obsolete.    Applied in many contexts (literally & figuratively), inventions (with and without hyphens) include fork-bomb, fork-buffet, fork-dinner, fork-head, rolling-fork, fork-over, fork-off & fork-up (the latter pair euphemistic substitutions for "fuck off" & "fuck-up).

Führerspork: Spork (left) from a flatware set (right) made for Adolf Hitler's 50^th birthday, sold at auction in 2018 for £12,500.  The items had been discovered in England in a house once owned by a senior military officer, the assumption being they were looted in 1945 (“souveniring” or “spoils of war” in soldiers' parlance), the items all bearing the Nazi eagle, swastika and Hitler's initials.  Auction houses can be inconsistent in their descriptions of sporks and in some cases they're listed as splayds, the designs meaning sometimes it's a fine distinction.

One quirk in the use of the word is the tendency of motorcyclists to refer to the front fork as “the forks”.  Used on almost every motorcycle made, the fork is an assembly which connects the front axle (and thus the wheel) to the frame, usually by via a pair (upper & lower) of yokes; the fork provides both the front suspension (springs or hydraulics) and makes possible the steering.  The reason the apparatus is often called “the forks” is the two most obvious components (the left & right) tubes appear to be separate when really they are two prongs connected at the top.  Thus, a motor cycle manufacturer describes the assembly (made of many components (clamp, tubes, legs, springs, dampers etc)) “a fork” but, because of the appearance, riders often think of them as a pair of forks, thus the vernacular “the forks”.  English does have other examples of such apparent aberrations such as a “pair of spectacles” which is sold as a single item but the origin of eye-glasses was in products sold as separate lens and users would (according to need) buy one glass (what became the monocle) or a pair of glasses.  That is a different structural creation than the bra which on the model of a “pair of glasses” would be a “pair of something” but the word is a clipping of “brassiere”.  English borrowed brassiere from the French brassière, from the Old French braciere (which was originally a lining fitted inside armor which protected the arm, only later becoming a garment), from the Old French brace (arm) although by then it described a chemise (a kind of undershirt) but in the US, brassiere was used from 1893 when the first bras were advertised and from there, use spread.  The three syllables were just too much to survive the onslaught of modernity and the truncated “bra” soon prevailed, being the standard form throughout the English-speaking world by the early 1930s.  Curiously, in French, a bra is a soutien-gorge which translates literally and rather un-romantically as “throat-supporter” although “chest uplifter” is a better translation.

2004 Dodge Tomahawk.

There have been variations on the classic fork and even designs which don’t use a conventional front fork, most of which have been variations on the “swinging arm” a structure which is either is or tends towards the horizontal.  One of the most memorable to use swinging arms was the 2004 Dodge Tomahawk, a “motorcycle” constructed around a 506 cubic inch (8.3 litre) version of the V10s used in the Dodge Viper (1991-2010 & 2013-2017) and the concept demonstrated what imaginative engineers can do if given time, money, resources and a disconnection from reality.  Designing a 500 horsepower (370 kW) motorcycle obviously takes some thought so what they did to equalize things a bit in what would otherwise be an unequal battle with physics was use four independently sprung wheels which allowed the machine to corner with a lean (up to 45^o said to be possible) although no photographs seem to exist of an intrepid rider putting this projection to the test.  Rather than a fork, swinging arms were used and while this presumably enhanced high-speed stability, it also meant the turning circle was something like that of one of the smaller aircraft carriers.  There were suggestions a top speed of some 420 mph (675 km/h) was at least theoretically possible although a sense of reality did briefly intrude and this was later revised to 250 mph (400 km/h).  In the Dodge design office, presumably it was thought safe to speculate because of the improbability of finding anyone both sufficient competent and crazy enough to explore the limits; one would find plenty of either but the characteristics rarely co-exist.  Remarkably, as many as ten replicas were sold at a reputed US$555,000 and although (mindful of the country’s litigious habits) all were non-operative and described as “art deco inspired automotive sculpture” to be admired as static displays, some apparently have been converted to full functionality although there have been no reports of top speed testing.

Britney Spears (b 1981): "Video clip with fork feature", Instagram, 11 May 2025.

Unfortunately, quickly Ms Spears deleted the more revealing version of the clip but for those pondering the messaging, Spearologists (a thoughtful crew devoted to their discipline) deconstructed the content, noting it came some days after she revealed it had been four months she’d left her house.  The silky, strapless dress and sweat-soaked, convulsing flesh were (by her standards) uncontroversial but what may have mystified non-devotees was the fork she at times held in her grasp.  Apparently, the fork was an allusion to her earlier quote: “Shit!  Now I have to find my FORK!!!”, made during what was reported as a “manic meltdown” (itself interesting in that it at least suggests the existence of “non-manic” meltdowns) at a restaurant, following the abrupt departure of her former husband (2022-2024) Hesam "Sam" Asghari (b 1994).  The link between restaurant and video clip was reports Mr Asghari was soon to be interviewed and there would be questions about the marriage.  One of her earlier posts had included a fork stabbing a lipstick (forks smeared with lipstick a trick also used in Halloween costuming to emulate facial scratches) and the utensil in the clip was said to be “a symbol of her frustration and emotional state.”  Now we know.

Großadmiral (Grand Admiral, equivalent to an admiral of the fleet (Royal Navy) or five star (fleet) admiral (US Navy)) Alfred von Tirpitz (1849–1930; State Secretary of the German Imperial Naval Office 1897-1916).

He's remembered now for (1) his role in building up the Imperial German Navy, triggering events which would play some part in the coming of World War I, (2) his distinctive twin-forked beard and (3) being the namesake for the Bismarck class battleship Tirpitz (1939-1944) which, although she hardly ever took to the high seas and fired barely a shot in anger, merely by being moored in Norwegian fjords, she compelled the British Admiralty to watch her with a mix of awe and dread, necessitating keeping in home waters a number of warships badly needed elsewhere.  Such was the threat his namesake battleship represented, just the mistaken belief she was steaming into the path of a convoy (PQ 17, June 1942) of merchant ships bound for the Russian port of Archangel caused the Admiralty to issue a “scatter order” (ie disperse the convoy from the escorting warships), resulting in heavy losses.  After a number of attempts, in 1944, she finally was sunk in a raid by RAF (Royal Air Force) bombers but, because some of the capsized hull remained visible above the surface, some wags in the navy insisted the air force had not "sunk the beast" but merely "lowered her to the waterline".  It wasn't until after the war the British learned the RAF's successful mission, strategically, had been unnecessary, earlier attacks (including the Admiralty's using mines placed by crews in midget submarines) having inflicted so much damage there was by 1944 no prospect of the Tirpitz again venturing far from her moorings.

Lieutenant General Nagaoka Gaishi san, Tokyo, 1920.

When Großadmiral von Tirpitz died in 1930, he and twin-fork beard were, in the one casket, buried in Bavaria's Münchner Waldfriedhof “woodland cemetery”.  The “one body = one casket” protocol is of course the almost universal practice but there have been exceptions and one was Lieutenant General Gaishi Nagaoka (1858-1933) who served in the Imperial Japanese Army between 1978-1908, including as vice chief of the general staff during the Russo-Japanese War (1904-1905).  While serving as a military instructor, one of his students was the future Generalissimo Chiang Kai-shek (1887-1975; leader of the Republic of China (mainland) 1928-1949 & the renegade province of Taiwan 1949-1975).  After retiring from the military, he entered politics, elected in 1924 as a member of the House of Representatives (after Japan in the 1850s ended its “isolation” policy, it’s political and social system were a mix of Japanese, British and US influences).  After he died in 1933, by explicit request, his impressive “handlebar” moustache carefully was removed and buried in a separate casket in Aoyama Cemetery.
