Poison & Venom

Poison (pronounced poi-zuhn)

(1) A substance with an inherent property that can impair function, cause structural damage, or otherwise injure or destroy life or impair health.

(2) Something harmful or pernicious, as to happiness or well-being.

(3) A slang term for alcoholic liquor.

(4) To administer poison to (a something living).

(5) To ruin, vitiate, or corrupt.

(6) In chemistry, a substance that retards a chemical reaction or destroys or inhibits the activity of a catalyst or enzyme).

(7) In nuclear physics, a substance that absorbs neutrons in a nuclear reactor and thus slows down the reaction.  It may be added deliberately or formed during fission.

(8) Variously in computing (often as "poison message"), a routine or instructing which can stop processes; the "poison queue" is a place to which these are diverted to prevent the running (a similar concept to a "quarantine zone").

1200-1250: From the Middle English poisoun, poyson, poysone, puyson & puisun (a deadly potion or substance (and figuratively, "spiritually corrupting ideas; evil intentions,"), from the twelfth century Old French poison & puison (drink, especially a "medical drink" (later "a (magic) potion; a poisonous drink"), from the Latin potionem (nominative potio) (a drinking, a drink) (and also "a poisonous drink"), from potare (to drink), from the primitive Indo-European root poi- & po- (to drink).  The earliest Lastin forms were pōtiōn (drink, a draught, a poisonous draught, a potion), from pōtō (I drink) & pōtāre (to drink).   The Middle English forms displaced the native Old English ator.  The Latin pōtiōn is the stem of pōtiō, the derive forms being pōtio & pōtiōnis.  The adjective poisonsome is obsolete and poisonous is used for all purposes.  Poison is a noun & verb, poisonousness & poisoner are nouns, empoison is a verb, poisoning is a noun & verb, poisoned is a verb & adjective, poisonous, poisonlike & poisonless are adjectives and poisonously is an adverb; the noun plural is poisons. 

Dry Cooder, Ronald Reagan, Can of Poison Meat.  The edited recording was sampled from a long interview conducted by US journalist Bill Moyers (1934–2025; White House Press Secretary 1965-1967) on 14 May 1979, some months before Ronald Reagan (1911-2004; POTUS 1981-1989) had declared his candidacy for POTUS. In the transcript the phrase is written as "can of poison meat" but the recording does suggest Mr Reagan (correctly) said "can of poisoned meat".

The evolution from Latin to French followed the pattern of other words (eg raison from rationem), the Latin word also the source of Old Spanish pozon, the Italian pozione and the Spanish pocion.  The modern and more typical Indo-European word for this is represented in English by virus and the slang sense of "alcoholic drink" is an Americanism dating from 1805.  Figurative use was first noted in the late fifteenth century although it appears not to have been applied to persons until 1910.  It was used as an adjective from the 1520s; with plant names from the eighteenth century.  Poison ivy first recorded 1784; poison oak in 1743, poison in 1915.  Poison-pen, the trolling of the time, was popularized 1913 by a notorious criminal case in Pennsylvania although the phrase dates from 1898.  The sense evolution was from "drink" to "deadly drink".  In some Germanic languages "poison" is aligned with the English gift (eg the Old High German gift, the German Gift, the Danish & Swedish gift and the Dutch gift & vergift).  This shift may have been partly euphemistic and partly the influence of the Greek dosis (a portion prescribed (literally "a giving")), used by Greek physicians to mean "a quantum of medicine".  Of persons detested or regarded as exerting baleful influence, poison and poisonous were in use by 1910 while the slang meaning "alcoholic drink" recorded as an an early nineteenth century invention of American English (as in "what's your poison?"); potus as a past-participle adjective in Latin meant "drunken".  The verb in the sense of "to poison, to give poison to" dates from the circa 1300 poisonen, from the Old French poisonner (to give to drink) and directly from the noun poison.  The figurative use in the sense of "to corrupt" emerged in the late fourteenth century.

In idiomatic use, the phrase “poisoned chalice” (a large drinking cup) refers to something which at first glance seems desirable but later is revealed to be disadvantageous or harmful.  It’s now used often in politics to describe the situation in which the leadership of a party is offered to someone even though it seems clear the prospects of success are slight.  This is a modern variant on the original sense in which things initially seemed benign, only later to cause harm or even death.  The earliest known use was by William Shakespeare (1564–1616) in The Tragedy of Macbeth (Macbeth, circa 1606) in the speech in which Macbeth flinches from the prospective murder of King Duncan.  “Poisoned compliment” is synonym of “asterism” or “left-handed compliment”; an insult disguised as a compliment or a compliment which can be interpreted as an insult.  “Damning with faint praise” can be used in the same way.  A “poisonmonger” was “one who peddles poison” and while that could be literal (ie a merchant who trades in poisons), it’s more often used figuratively of those who speak with a “poison tongue” or who wield a “poison pen”.  A “taste of one's own poison” was synonymous with “taste of one's own medicine” and referred to harsh treatment inflicted on one who previously made other suffer the treatment.  To “pick (or “choose”) one’s poison” was to be compelled to choose between two unappealing options.  The variant “a man must be permitted to choose his own poison” was a summation of “liberal” periods of rule within the Ottoman Empire (1299-1922) when the consumption of alcohol was tolerated (at least for infidels who were anyway destined for Hell).  To say “one man’s meat is another’s poison” is to admit people have differing tastes; what pleases one person may displease another. 

“Well poisoning” still is practiced and means literally “to make the water supply undrinkable by means of adulteration” (not necessarily with “poison” in the narrow technical sense).  A wartime technique known since at least antiquity, it was used both as an offensive weapon (a terror tactic to disrupt and depopulate a target area) and defensively (as a scorched earth tactic to deny an invading army sources of clean water). Historically, rotting corpses (animal and human) were thrown down wells, making it an early example of biological warfare and that was an especially potent technique because corpses known to have died from transmissible diseases (common during the "age of epidemics" that was the Medieval period) such as bubonic plague or tuberculosis often were available to be "weaponized".  Figuratively, “to poison the well” was pre-emptively to raise ad hominem arguments in order to discredit someone, the concept thus a type of informal fallacy where adverse information about a target is presented to an audience with the intention of devaluing what they’re about to say.  That makes it a certain type of argumentum ad hominem and the phrase was first in this sense used by convert Roman Catholic theologian Cardinal John Henry Newman (1801-1890) in Apologia Pro Vita Sua (A defence of one's own life, 1864).  The proverb “The damage that a substance causes is determined more by its quantity than by its essence” is from toxicology and references the phenomenon that while some substances may for life be beneficial or even essential, in certain quantities they can be damaging or even fatal; for humans, ingesting even pure water can prove lethal if enough is consumed in a certain period, toxicity for healthy adults reached with as little as 20 litres (4.4 imperial gallons, 5.3 US gallons) taken over a few hours.

Venom (pronounced ven-uhm)

(1) The poisonous fluid that some animals, as certain snakes and spiders, secrete and introduce into the bodies of their victims by biting, stinging etc.

(2) Something resembling or suggesting poison in its effect; spite; malice.

(3) Poison in general (inaccurate, now archaic).

(4) To make venomous; envenom (archaic).

(5) Malice, spite.

1175–1225: A variant of the Middle English venim & venym (poison secreted by some animals and transferred by biting) from the Anglo-Norman & Old French venim, venin (poison; malice), from the Vulgar Latin venīmen (source also of the Italian veleno and the Spanish veneno), from the Latin venēnum (magical herb or potion, poison (and in pre-Classical times "drug, medical potion" also "charm, seduction" probably originally "love potion")).  Root was the Proto-Italic weneznom (lust, desire), from the primitive Indo-European wenh (to strive, wish, love) from wen (to desire; to strive for).  Related forms included the Sanskrit वनति (vanati) (gain, wish, erotic lust) and the Latin Venus.   The various deformations in post-Latin languages happened apparently by process of dissimilation with the modern spelling in English more or less standardized by the late fourteenth century.  In figurative use, to have "venom in one's voice" was to express thoughts or feelings marked by spite or malice (vitriolic talk); that of course has been common in human discourse since even before structured language developed but the use of "venom" or "venomous" as a descriptor has been in use since at least the late twelfth century.  The adjective venomosalivary (relating to venom and saliva) is now rare and appears only in historic references while the adjective venonsome is obsolete and venomous is used for all purposes.  Venom is a noun, verb & adjective, venomousness, venomization & venomosity are nouns, venomless, venomlike, venomosalivary, venomsome, venomous & venomic are adjectives, venomize, venoming & envenomate are verbs, venomed is a verb & adjective and venomously is an adverb; the noun plural is venoms.

Sometimes similar consequences but linguistically not interchangeable

A venomous white-lipped pit viper (Trimeresurus insularis), ready to strike; the lovely blue ones are rare; most are green.  That may be an example of survival of the fittest given the environments in which they dwell tend more to be green than blue.  As a footnote, the phrase “survival of the fittest” often is attributed to Charles Darwin (1809-1882) but nowhere does in appear in his epoch-making On the Origin of Species (1859); it was coined by English polymath Herbert Spencer (1820–1903), first used in his Principles of Biology (1864).  Sometimes misunderstood, “fittest” means “best fitted to the environment”, not “strongest, fastest, or most physically fit”.  In other words, organisms most likely to survive as a species are those best adapted to their niche or able to adapt to environmental change.

Poison and venom often are used interchangeably because once in the body, the chemicals can do similar damage, attacking the heart, brain or other vital organs but the meanings are different.  That said, there are many venoms which can be ingested without ill-effect because they are dangerous only if entering the bloodstream although that can happen through a minor cut in the mouth so the practice is not without risk.  Typically, venomous creatures bite, sting or stab their victims whereas for poisonous organisms to affect the living, they have to be bitten, inhaled or touched.  The venomous thus need a way in, like fangs or teeth.  The useful rule is: If one bites something and one dies, what one bit contained poison; if something bites one and one dies, one was bitten by something venomous.  Of course one is just as dead whether the cause was ingesting poison, the bite of a venomous snake or being murdered by the Freemasons but the difference is important for those signing death certificates.

Nail

Nail (pronounced neyl)

(1) A slender, typically rod-shaped rigid piece of metal, usually in many lengths and thicknesses, having (usually) one end pointed and the other (usually) enlarged or flattened, and used for hammering into or through wood, concrete or other materials; in the building trades the most common use is to fasten or join together separate pieces (of timber etc).

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”.

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.

Heptadecaphobia

Heptadecaphobia (pronounced hepp-tah-dech-ah-foh-bee-uh)

Fear of the number 17.

1700s: The construct was the Ancient Greek δεκαεπτά (dekaepta) (seventeen) + φόβος (phobos).  The alternative form is septadecaphobia, troubling some the purists because they regard it as a Greek-Latin mongrel, the construct being the Latin septem (seven) + deca, from the Latin decas (ten), from the Ancient Greek δεκάς (dekás) (ten) + the Ancient Greek φόβος) (phobos) (fear).  Heptadecaphobia deconstructs as hepta- “seven” + deca (ten) + phobos.  The suffix -phobia (fear of a specific thing; hate, dislike, or repression of a specific thing) was from the New Latin, from the Classical Latin, from the Ancient Greek -φοβία (-phobía) and was used to form nouns meaning fear of a specific thing (the idea of a hatred came later).  Heptadecaphobia, heptadecaphobist, heptadecaphobism, heptadecaphobiac and heptadecaphobe are nouns, heptadecaphobic is a noun & adjective and heptadecaphobically is an adverb; the common (sic) noun plural is heptadecaphobes and they should number 59 million-odd (the population of Italy).

Morphologically, “heptadecaphilliac” is possible but is clumsy and unnecessary, the standard noun agent (-phile) rendering it redundant and although used, not all approve of the suffix -phobiac because it’s a later hybrid formation from modern English and thus judged “less elegant”.  The opposite condition (a great fondness for 17) is the noun heptadecaphilia, those with the condition being Heptadecaphiles, the derived words following the conventions used with heptadecaphobia.  Whether any of the derived forms have much (or ever) been used beyond lists asserting they exist (which, except as abstractions, may be dubious) is unlikely but concerned Italians should note the noun heptadecaphobist would seem to imply doctrinal adherence rather than suffering the fear.  Still, it’s there if the need exists for precision in one’s behavioural descriptors.  Modern English constructions (like heptadecaphobia) built from Greek morphemes are neo-classical” compounds rather than a “proper” words from the Ancient Greek and while some amuse or appal the classicists, in practice, variations in suffix-use have long be tolerated.

No fear of 17: Sydney Sweeney (b 1997) in photo-shoot for Frankies Bikini Collection, Seventeen magazine, March 2023.

In Classical Greek, the cardinal number 17 was ἑπτακαίδεκα (heptakaídeka; literally “seven-and-ten”) but the Ancients were as adept as us at clipping for convenience and the variant ἑπταδέκα (heptadéka; literally “seven-ten”) also exists in surviving texts.  The shorter element embedded in heptadecaphobia corresponds to heptadeca- (from ἑπταδέκα) and genuinely that is Classical Greek, although, on the basis of the count from what documents are extant, it was less common than ἑπτακαίδεκα. The latter-day hybridization was inevitable because, as far as in known, “seventeen” had not before been used as a combining stem in compounds.  In English, the convention in neoclassical formation tends the sequence: (1) take the cardinal form, (2) drop the inflection and (3) treat it as a stem, thus the construct heptadeca + phobia, familiar to structuralists in the more common triskaidekaphobia which uses the Greek tris-kai-deka (“three and ten”) despite in genuine Greek morphology, compounds being not usually directly from ἑπταδέκα as a bound stem.  It’s better to follow modern practice rather than try to conjure something “classically pure” because although one could argue heptakaidekaphobia (closer to ἑπτακαίδεκα) is a better tribute to Antiquity, as well as being historically unattested, it’s phonetically cumbersome which seems a worse linguistic sin.

Just because a “fear of a number” is listed somewhere as a “phobia” doesn’t mean the condition has much of a clinical history or even that a single case is to be found in the literature; many may have been coined just for linguistic fun and students in classics departments have been set assessment questions like “In Greek, construct the word meaning “fear of the number 71” (the correct answer being “hebdomekontahenophobia”).  Some are well documented such as tetraphobia (fear of 4) which is so prevalent in East Asia it compelled BMW to revise the release strategy of the “4 Series” cars and triskaidekaphobia (fear of 13) which has such a history in the West it’s common still for hotels not to have a 13^th floor or rooms which include “13”, something which in the pre-digital age was a charming quirk but when things were computerized added a needless complication.  The use of the actual number is important because in such a hotel the “14^th” floor is (in the architectural sense) of course the 13^th but there’s little to suggest there’s ever been resistance from guests being allocated room 1414.

Some number phobias are quite specific: Rooted in the folklore of Australian cricket is a supposed association of the number 87 with something bad (typically a batter (DEI (diversity, equity & inclusion) means they're no longer "batsmen") being dismissed) although it seems purely anecdotal and more than one statistical analysis (cricket is all about numbers) has concluded there's nothing “of statistical significance” to be found and there’s little to suggest players take the matter seriously.  One English umpire famously had “a routine” associated with the score reaching a “repunit” (a portmanteau (or blended) word, the construct being re(eated) +‎ unit) (eg 111, 222, 333 etc) but that was more fetish than phobia.

Other illustrative number phobias include oudenophobia (fear of 0), (trypophobia (fear of holes) said to sometimes be the companion condition), henophobia (fear of 1) (which compels sufferer to avoid being associated with “doing something once”, being the “first in the group” etc), heptaphobia (fear of 7) (cross-culturally, a number also with many positive associations), eikosiheptaphobia (fear of 27) (a pop-culture thing which arose in the early 1970s when a number of rock stars, at 27, died messy, drug-related deaths), tessarakontadyophobia (fear of 42) (which may have spiked in patients after the publication of Douglas Adams’ (1952–2001) Hitchhiker's Guide to the Galaxy (1979-1992), enenekontenneaphobia (fear of 99) (thought not related to the Get Smart TV series of the 1960s), tetrakosioeikosiphobia (fear of 420) (the syndrome once restricted to weed-smokers in the US but long internationalized), the well-documented hexakosioihexekontahexaphobia (fear of 666), heftakosioitessarakontaheptaphobia (fear of 747) (though with the withdrawal from passenger service of the tough, reliable (four engines and made of metal) Boeing 747 and its replacement with twin-engined machines made increasingly with composites and packed with lithium-ion batteries, a more common fear may be “not flying on a 747”, most common among heftakosioitessarakontaheptaphiles).  Enniakosioihendecaphobia (fear of 911) was, in the US, probably a co-morbidity with tetrakosioeikosiphobia but it may also have afflicted also those with a bad experience of a pre-modern Porsche 911 (1963-) which, in inexpert hands, could behave as one would expect of a very powerful Volkswagen Beetle, the most acute cases manifesting as triskaidekaphobia (fear of 930, that number being the internal designation for the original 911 Turbo (1974-1989), the fastest of the breed, soon dubbed the "widow-maker").

Nongentiseptuagintatrestrillionsescentiquinquagintanovemmiliacentumtredecimdeciesoctingentivigintiquattuormiliatrecentiphobia (fear of 973,659,113,824,315) describes a the definitely rare condition and it's assumed that was word was coined by someone determined to prove it could be done. There’s also compustitusnumerophobia (fear of composite numbers), meganumerophobia (fear of large numbers), imparnumerophobia (fear of odd numbers), omalonumerophobia (fear of even numbers), piphobia (fear of pi), phiphobia (fear of the golden ratio), primonumerophobia (fear of prime numbers), paranumerophobia (fear of irrational numbers), neganumerophobia (fear of negative numbers) and decadisophobia (fear of decimals).  All such types are unrelated to arithmophobia (or numerophobia) which is the "fear of numbers, calculations & math", a syndrome common among students who "just don't get it" and there are many because those "good at math" and those not really are two separate populations; it's rare to be able to transform the latter into the former, a better solution being to send them to law school where many flourish, needing to master the arithmetic only of billing their time in six-minute increments (1/10th of an hour).  Having ten fingers and thumbs, most manage the calculations.  The marvellous Wiki Fandom site and The Phobia List are among the internet’s best curated collection of phobias.

The only one which debatably can’t exist is neonumerophobia (fear of new numbers) because, given the nature of infinity, there can be no “new numbers” although, subjectively, a number could be “new” to an individual so there may be a need.  Sceptical though mathematicians are likely to be, the notion of the “new number” ("zero" debatably the last) has (in various ways) been explored in fiction including by science fiction (SF or SciFi) author & engineer Robert A Heinlein (1907–1988) in The Number of the Beast (1980), written during his “later period”.  More challenging was Flatland: A Romance of Many Dimensions by English schoolmaster & Anglican priest Edwin Abbott (1838–1926) which was published under the pseudonym “A Square”, the layer of irony in that choice revealed as the protagonist begins to explore dimensions beyond his two-dimensional world (in Victorian England).  Feminists note also Ursula K Le Guin’s (1929–2018) The Left Hand of Darkness (1969) in which was created an entirely new numerical system of “genderless" numbers”.  That would induce fear in a few.

In entymology, there are insects with no fear of the number 17.  In the US, the so-called “periodical cicadas” (like those of the genus Magicicada) exist in a 17 year life cycle, something thought to confer a number of evolutionary advantages, all tied directly to the unique timing of their mass emergence: (1) The predator satiation strategy: The creatures emerge in massive numbers (in the billions), their sheer volume meaning it’s physically impossible for predators (both small mammals & birds) to eat enough of them to threaten the survival of the species. (2) Prime number cycles: Insects are presumed unaware of the nature of prime numbers but 17 is a prime number and there are also periodic cicadas with a 13 (also a prime) year cycle.  The 13 (Brood XIX) & 17-year (Brood X) periodic cicadas do sometimes emerge in the same season but, being prime numbers, it’s a rare event, the numbers' LCM (least common multiple) being 221 years; the last time the two cicadas emerged together was in 1868 and the next such event is thus expected in 2089.  The infrequency in overlap helps maintain the effectiveness of the predator avoidance strategies, the predators typically having shorter (2-year, 5-year etc) cycles which don’t synchronize with the cicadas' emergence, reducing chances a predator will evolve to specialize in feeding on periodical cicadas. (3) Avoidance of Climate Variability: By remaining underground for 17 years, historically, periodical cicadas avoided frequent climate changes or short-term ecological disasters like droughts or forest fires. The long underground nymph stage also allows them to feed consistently over many years and emerge when the environment is more favorable for reproduction.  Etymologists and biological statisticians are modelling scenarios under which various types of accelerated climate change are being studied to try to understand how the periodic cicadas (which evolved under “natural” climate change) may be affected. (4) Genetic Isolation: Historically, the unusually extended period between emergences has isolated different broods of cicadas, reducing interbreeding and promoting genetic diversity over time, helping to maintain healthy populations over multiple life-cycles.

There are a variety of theories to account for the Italian superstition which had rendered 17 the national “unlucky number” but it does seem to be due primarily to a linguistic and symbolic association from ancient Rome.  The most accepted explanation is that in Roman numerals 17 is XVII which, anagrammatically, translates to VIXI (Latin for “I have lived” (the first-person singular perfect active indicative of vīvō (to live; to be alive)), understood in the vernacular as “my life is over” or, more brutally: “I am dead”.  It was something which appeared often on Roman tombstones, making an enduring record which ensured the superstition didn’t have to rely on collective memory or an oral tradition for inter-generational transfer.  That would have been ominous enough but Romans noted also that Osiris, the Egyptian god of, inter alia, life, death, the afterlife and resurrection, had died on the 17^th day of the month, 17 thus obviously a “death number” to the logical Roman mind and the worst 17^th days of the month were those which coincided with a full moon.  The cosmic coincidence was an intensifier in the same sense that in the English-speaking world the conjunction leading to a Friday falling on the 13^th makes the day seem threatening.  Thus, just as in some places hotels have neither 13^th floor or rooms containing “13”, in Italy it’s “17” which is avoided although not having a row 17 in its airliners didn’t save Alitalia (Società Aerea Italiana, the now-defunct national carrier) from its COVID-era demise.  Of course not labelling a row or floor “13” or “17” doesn’t mean a 13^th or 17^th something doesn’t exist, just that it’s called “14” or “18” so it’s the symbolic association which matters, not the physical reality.  Mashing up the numerical superstitions, that 17 is an “unlucky number” shouldn’t be surprising because it’s the sum of 13 + 4, the latter being the most dreaded number in much of East Asia, based on the pronunciation resembling “death” in both Chinese and Japanese.

In automotive manufacturing, there was nothing unusual about unique models being produced for the Italian domestic market, the most common trick being versions with engines displacing less than 2.0 litres to take advantage of the substantially lower tax regime imposed below that mark.  Thus Ferrari (1975-1981) and Lamborghini (1974-1977) made available 2.0 litre V8s (sold in RoW (rest of the world) markets variously in 2.5 & 3.0 litre displacements), Maserati a 2.0 V6 (usually a 3.0 in the Maserati Merak (1972-1983) although it appeared in 2.7 & 3.0 litre form in the intriguing but doomed Citroën SM (1970-1975)) and Mercedes-Benz created a number of one-off 2.0 litre models in the W124 range (1974-1977) exclusive to the Italian domestic market (although an unrelated series of 2.0 litre cars was also sold in India).  Others followed the trend although, the more expensive they were, the less appeal seemed to exist despite, in absolute terms, the saving increasing as the price rose.  Maserati offered a twin-turbo 2.0 in the aptly named BiTurbo, BMW did a one off 320is and Alfa Romeo produced a run of 2.0 V6s.

From an engineering point of view, most audacious doubtlessly was the 2.0 litre version of TVR's V8S (1991-1994).  Supplied usually with a 4.0 litre version of the versatile Rover V8, the capacity of the version for the Italian market was halved by de-stroking, the bore of 88.9 and stroke of 40.25 mm creating an outrageously oversquare bore/stroke ratio of 45.28 but, with the assistance of a supercharger, the quirky engine almost matched in power and torque the naturally aspirated original with twice the displacement; It was a classic example of the effectiveness of forced-aspiration although it did demand of drivers a different technique.  By comparison, the Formula One BRM H16’s (1966-1967) bore & stroke was 69.8 x 49.9 mm and it was so oversquare to reduce the frictional losses which would have been induced had a longer stroke been used with that many cylinders; its bore/stroke ration was 71.48 compared with the almost square BRM V16 designed in the 1940s, the latter able to be in that configuration because (1) it was supercharged and (2) being only 1.5 litres, the stroke was anyway physically short in absolute terms.  The 2.4 litre V8s used in Formula One between 2006-2013 had to have a maximum bore of 98 and stroke of 40 mm (bore/stroke ratio 40.81) and that’s an indication of the characteristics the 2.0 litre TVR V8S offered.  Disappointingly, it was an experience few Italians sought and only seven were built.

It was Suzuki which had more success with work-arounds to Rome’s tiresome regulations.  Their two-stroke, triple cylinder GT380 (1972-1980) motorcycle was for most of its existence made with an actual displacement of 371 cm³ but in 1975, the Italian government passed a law banning the importation of motor-cycles under 380 cm³ and weighing less than 170 kg.  Accordingly, the Japanese produced a “big bore” 380 exclusively for the Italian market displacing an actual 384 cm³.  The portly triple would never have run afoul of the weight limit but just to avoid any unpleasantness, the data plate riveted to the frame recorded a verified mass of 171 kg.  Honor apparently satisfied on both sides, the GT380 remained available in some places until 1980, outliving the Suzuki’s other two-strokes triples by three seasons.

US advertisement for the Renault 17 (1974), the name Gordini adopted as a "re-brand" of the top-of-the-range 17TS,  Gordini was a French sports car producer and tuning house, absorbed by Renault in 1968, the name from time-to-time used for high-performance variants of various Renault models.

One special change for the Italian market was a nod to the national heptadecaphobia, the car known in the rest of the world (RoW) as the Renault 17 (1971-1979) sold in Italy as the R177.  For the 17, Renault took the approach which had delivered great profits: use the underpinnings of mundane mass-produced family cars with a sexy new body draped atop.  Thus in the US the Ford Falcon (1959-1969) begat the Mustang (1964-) and in Europe Ford made the Capri (1968-1976) from the Cortina (1962-1982).  Opel’s swoopy GT (1968-1973) was (most improbably) underneath just the modest Kadett.  It wasn’t only the mass-market operators which used the technique because in the mid 1950s, Mercedes-Benz understood the appeal of the style of the 300 SL (W198, 1954-1957) was limited by the high price which was a product of the exotic engineering (the space-frame, gullwing doors, dry sump and the then novel MFI (mechanical fuel-injection)), the solution being to re-purpose the platform of the W120, the small, austere sedan which helped the company restore its fortunes in the post-war years before the Wirtschaftswunder (economic miracle) was celebrated in 1959 with the exuberance of the Heckflosse (tailfin) cars (1959-1968).  On the W120 platform was built the 190 SL (W121, 1955-1963), an elegant (it not especially rapid) little roadster which quickly became a trans-Atlantic favourite, particularly among what used to be called the “women’s market”.

Only in Italy: The Renault 177, exclusively for heptadecaphobes.

Using the same formula, the Renault 17 was built on the underpinnings of the Renault 12, a remarkably durable platform, introduced in 1969 and, in one form or another, manufactured or assembled in more than a dozen countries, the last not produced until 2006.  Like the Anglo-German Ford Capri, the 17 was relatively cheap to develop because so much was merely re-purposed but for a variety of reasons, it never managed to come close to match the sales of the wildly successful Ford, FWD (front wheel drive) not then accepted as something “sporty” and Renault's implementation on the 17 was never adaptable to the new understanding of the concept validated by FWD machines such as Volkswagen’s Golf GTi which would define the “hot hatch”.  Like most of the world, the Italians never warmed to the 17 but presumably the reception would have been even more muted had not, in deference to the national superstition about the number 17, the name been changed to “Renault 177”, the cheaper companion model continuing to use the RoW label: Renault 15.
