Nudge

Nudge (pronounced nuhj)

(1) To push slightly or gently, especially with the elbow; a gentle push.

(2) To give a nudge.

(3) To annoy with persistent complaints, criticisms or pleas; to nag.

(4) In behavioral economics (and other disciplines), the use of positive reinforcement and indirect suggestions as ways to influence behavior.

(5) In internet use, a feature of instant messaging software used to get the attention of another user, as by shaking the conversation window or playing a sound.

(6) In gambling (slot machines; fruit machines etc), the rotation by one step of a reel of the player's choice.

(7) Slightly to move.

(8) In slang as “giving it a (bit of a) nudge”, high alcohol consumption in the context of binge drinking.

1665-1675: From the Middle English, a variant of the earlier nidge & knidge, akin to the Old English cnucian & cnocian (to knock).  In other languages, there were similar forms.  There was the Yiddish nudyen (to bore), first noted in English in 1877, apparently derived from the Polish nudzić (sometimes written as nudnik in translation (and both from Slavic words meaning "fret, ache”)) and in the 1960s modern Yiddish adapted nudge (nudjh in Modern Yiddish) to mean complainer or nagger (presumably to satisfy the demand from daughters-in-law needing descriptors of Jewish mothers-in-law).  In the Nordic region, dating from the seventeenth century there was the Icelandic nugga (to push, rub or massage) and the Norwegian nugge or nyggje (to jostle, rub, push slightly with the elbow), from the Proto-Germanic hnōjaną (to smooth, join together), from the primitive Indo-European kneh- which may have had some relationship to the Ancient Greek κνάω (knáō) (to scratch, scrape), source of the English noun acnestis (the section of an animal's skin that it cannot reach in order to scratch itself, usually the space between the shoulder blades).  There was also the Scots nodge (to push, poke, nudge), knidge (to push, squeeze), gnidge (to rub, press, squeeze, bruise) & knudge (to squeeze, press down with the knuckles) and the Middle Low German nucke, nücke & gnücke (a sudden push, shock, impetus).  Nudge is a noun & verb, nudged & nudging are verbs, nudger is a noun, nudgy is an adjective and nudgingly is an adverb; the noun plural is nudges. 

Nudge theory

The most famous example of a nudge is the etching of the image of a housefly into the urinals at Amsterdam's Schiphol Airport (actually an idea dating back decades).  It’s to nudge men towards “improving the aim" and one feminist critic suggested images of dartboards so “men could keep score.”  She may have been taking the piss.

First appearing in the 2008 book Improving Decisions about Health, Wealth, and Happiness by University of Chicago economist & Nobel Laureate Richard Thaler (b 1945) and Harvard Law Professor Cass Sunstein (b 1954), the concept of nudge theory became part of the orthodoxy of behavioral sciences, political theory and economics (although not without attracting critics).  It suggests the use of positive reinforcement and indirect suggestions to try to achieve non-forced compliance with desirable objectives.  Nudge theory attracted criticism from both left and right because it is a form of social engineering although the specifics of the critiques vary but it certainly was organizationally influential, the seemingly radical that government could maintain the freedoms enjoyed by citizens in the democratic West while simultaneously helping them make better choices in matters relating to their health, happiness & wealth.  Within months of publication, over 500 nudge units or departments had been created around the world, including institutions like the World Bank and United Nations (UN).  However, in recent years, critics have challenged the both the effectiveness of the idea and even that nudges by governments are inherently less intrusive and thus more likely to sustain civil freedoms than other approaches (taxes, legislation etc).  One obvious difficulty for both sides of the argument is that any attempt to find a correlation between nudges and alleged outcomes cannot easily be reduced to numbers so conventional economic modeling is often not useful.

Noted nudgers: Lindsay Lohan (b 1986) at dawn, resting in a Cadillac Escalade, Los Angeles, May 2007 (left) and Donald Trump (b 1946; US president 2017-2021 and since 2025) shaking hands with Richard Nixon (1913-1994; US president 1969-1974), Westin Galleria ballroom, Houston, Texas, 1989 (right).  The idiomatic Australian phrase “gave it a bit of a nudge last night” is an allusion to having taken too much strong drink.  In one of his less remembered remarks, Richard Nixon observed: “The mark of a leader, is whether he gives history a nudge.”  That Nixon certainly did although, were he to have his time again, some of the nudges would have been in a different direction and Lindsay Lohan too might do things a little differently.  Mr Trump would change not a thing.

Nictate

Nictate (pronounced nik-teyt)

To wink.

1690s: From the Medieval Latin nictitātus, from the Latin nictātus, past participle of nictāre (to wink, fidget, blink, signal with the eyes), inflection of nictō (to blink, to wink; to signal with the eyes (and figuratively (of fire) to flash and to strive, to exert great effort).  It was related to nicere (to beckon) and the ultimate source was the primitive Indo-European root kneigwh (to blink, to draw together (the eyes or eyelids)) (related to kneygwh (to bend, to droop), the source also of the Gothic hniewan and the Old High German nigan (to bow, be inclined).  It was cognate with connīveō, nītor (to bear or rest upon something).  Nictate, nictitated & nictitating are verbs, nictitate is an adjective and nictator & nictation are noun; the noun plurat is nictators.  Nictate was used from the 1690s, nictitated & nictitating emerged in the 1710s and nictitation in the 1820s.

The alteration nictitate

The intransitive verb nictitate is sometimes described as an alternative spelling of nictate but it’s more a niche alteration for a specialised niche.  Nictitate’s origins are the same as nictate, coming from the Latin word for winking, nictāre.  The addition of the extra syllable is thought to have been under the influence of Latin verbs ending in -itare, such as palpitare and agitare (from which, respectively, English gained palpitate and agitate).  The niche is in zoology, a role it’s played since scientists in the early eighteenth century began to describe a “nictitating membrane”, the so-called "third eyelid", the thin, usually transparent membrane in the eyes of birds, fishes, and other vertebrates, the function of which is to help keep the eyeball moist and clean.  In zoology, the word referred either to a wink or blink but when applied to humans (a species in which a wink can be a non-verbal clue transmitting meaning) it's used exclusively of winks.

Noted nictator, Lindsay Lohan, nictating.

Vladimir Putin (b 1952; president or prime minister of Russia since 1999).  Mr Putin is a known nictator and for those individuals (or countries) at which his nictations are directed, the consequences can be good or bad.  Simultaneously, Mr Putin can “turn a blind eye” while giving a “nod and a wink”.

The act of nictation (as wink) is featured in idiomatic English phrases including a nod is as good as a wink (the hint, suggestion etc can be understood without further explanation) (and sometimes embellished as a nod is as good as a wink to a blind horse which must mystify those learning the language), God winks (an event or personal experience, often identified as coincidence, so astonishing that it is seen as a sign of divine intervention, especially when perceived as the answer to a prayer), in the wink of an eye (something happening instantaneously or very quickly (in the blink of an eye and in the twinkling of an eye are both synonymous), forty winks (a brief sleep, a nap), a wink at (an allusion to something or someone) and nudge nudge wink wink (a hint that a euphemism is being deployed).  There’s also the ominous sounding butt wink (in the sport of weight-lifting, an error while performing a squat of bending the lower back and moving the pelvis in under the body).

Homologate

Homologate (pronounced huh-mol-uh-geyt or hoh-mol-uh-geyt)

(1) To approve; confirm or ratify.

(2) To register (a specific model of machine (usually a car), engine or other component) in either general production or in the requisite number to make it eligible for racing competition(s).

(3) To approve or ratify a deed or contract, especially one found to be defective; to confirm a proceeding or other procedure (both mostly used in Scottish contract law).

1644: From the Latin homologāt (agreed) & homologātus, past participle of homologāre (to agree) from the Ancient Greek homologeîn (to agree to, to allow, confess) from homologos (agreeing), the construct being homo- (from the Ancient Greek ὁμός (homós) (same) + legein (to speak).  Homologate, homologated and homologating are verbs, homologation is a noun.

Once often used to mean “agree or confirm”, homologate is now a niche word, restricted almost wholly to compliance with minimum production numbers, set by the regulatory bodies of motorsport, to permit use in sanctioned competition; the words "accredit, affirm, approbate, authorize, certify, confirm, endorse, ratify, sanction, warrant & validate etc" are otherwise used for the purpose of agreeing or confirming.  It exists however still in Scottish law as a legal device, used (now rarely) retrospectively to declare valid an otherwise defective contract.  The best known application was to validate contracts of marriage where some technical defect in the legal solemnities had rendered the union void.  In such cases case a court could hold the marriage “. . . to be homologated by the subsequent marriage of the parties”.  It was a typically Scottish, common-sense application of the law, designed originally to avoid children being declared bastards (at a time which such a label attracted adverse consequences for all involved), vaguely analogous with a “contract by acquiescence” from contract law though not all were pleased: one dour Scottish bishop complained in 1715 that homologate was a "hard word".

Case studies in homologation

1962 Ferrari GTO.

In 1962, fearing the effectiveness of Jaguar’s new E-Type (XKE), the sleek lines of which made it look faster even than it was, Ferrari created a lighter, more powerful version of their 250 GT, naming the new car 250 GTO (Gran Turismo Omologato (Grand Touring Homologated)).  The regulatory body, the Fédération Internationale de l'Automobile (FIA) required a production run of at least 100 "identical" examples within twelve months for a car to be homologated for the Group 3 Grand Touring Car class but Ferrari built only 33, 36, 39 or 41 (depending on how one treats the variations and 36 is most quoted) 250 GTOs, thus the enduring debate about whether the thing violated the rules.

Ferrari GTO production numbers 1961-1964.

There was though some "wriggle room" in those rules in that "special coachwork" was permitted for racing variants of a homologated Group 3 model, but mechanical modifications were banned and while strengthening of a chassis, was permitted, weight reduction of the structure was not.  On any objective reading of the rule book, the fact the 250 GTO used a custom, narrow-tube frame unlike any other 250 GT, certification should have been denied until the requisite 100 had within twelve months been built.  However, the FIA was aware of the "Ferrari factor" in these matters.  Race organizers had much influence on the FIA's thought processes and they really wanted Ferraris on their grids because people paid money to see the things race so the GTO was granted homologation as a legitimate "development" the 250 GT Berlinetta SWB (Short wheelbase), the papers for which had been first issued in 1960.  It was as an appendage to this document that the GTO (as "a clause driving through a loophole" as one critic put it) competed between 1961-1964.  They’re now a prized item, one in a private transaction selling in 2018 for a reputed, then world-record, US$70 million which makes it the second most expensive car ever sold, topped only by the US$142 million paid in 2022 for one of the two Mercedes-Benz 300 SLR (W196S) Uhlenhaut gull-wing coupés.

1965 Ferrari 250 LM.

The FIA’s legislative largess didn’t extend to Ferrari’s next development for GT racing, the 250 LM. The view of il Commendatore was the 250 LM was an evolution as linked to the 250 GT’s 1960 homologation papers as had been the 250 GTO and thus deserved another certificate of extension.  Stung by the criticism that Ferrari were being afforded blatant favoritism (the FIA dubbed by some: "Ferrari International Assistance"), the FIA which pointed out 250 LM (1) was mid rather than front-engined, (2) had a wholly different body and (3) used a different frame and suspension.  Neither party budged so the 250 LM could run only in the prototype class until 1966 when it gained homologation as a Group 4 Sports Car.  Although less competitive against the true prototypes, it’s speed and reliability was enough for a private entry to win the 1965 24 Hours of Le Mans, a Ferrari’s last victory in the race until 2023.  One quirk of the 250 LM was that when the FIA ruled against homologation, the point of retaining the 3.0 litre displacement became irrelevant and almost all 250 LMs used a 3.3 litre engine so under Ferrari’s naming convention, the thing properly should have been called a 275 LM.  In February 2025, at RM Sotheby's Paris Auction, the Scaglietti-bodied 1964 250 LM which won at Le Mans in 1965 (and the only Ferrari from the era to compete in six 24 hour races) was sold for US$36.2 million.  The car had for decades been on display at Indianapolis Motor Speedway Museum, like the 1954 Mercedes-Benz W196R Stromlinienwagen (streamliner) which a few days earlier had fetched US$53 million.

The famous photograph of the first 25 Porsche 917s, lined up outside the factory, Stuttgart, FRG (Federal Republic of Germany, the old West Germany), 20 April, 1969.

In 1969, needing to build twenty-five 917s to be granted homologation, Porsche did... sort of.  When the FIA inspectors turned up to tick the boxes, they found the promised twenty-five cars but most were in pieces.  Despite assurances there existed more than enough parts to bolt together enough to qualify, the FIA, now less trusting, refused to sign off, despite Porsche pointing out that if they assembled them all, they'd then just have to take them apart to prepare them for the track.  The FIA conceded the point but still refused to sign-off.  Less than a month later, probably nobody at the FIA believed Porsche when they rang back saying twenty-five completed 917s were ready for inspection but the team dutifully re-visited the factory.  There they found the 25, lined-up in a row.  Duly the delegation granted homologation, declining the offer of twenty-five test-drives which was just as well because so hurriedly had many of the 917s been assembled (it was such a rush secretaries, accountants and such were press-ganged to help) that many could only be started, put in first gear and driven a few metres.

1969 Dodge Daytona (red) & 1970 Plymouth Road Runner Superbird (blue).

By the mid 1950s, various NASCAR (National Association for Stock Car Auto Racing) competitions had become wildly popular and the factories (sometimes in secret) provided support for the racers.  This had started modestly enough with the supply of parts and technical support but so tied up with prestige did success become that soon some manufacturers established racing departments and, officially and not, ran teams or provided so much financial support some effectively were factory operations.  NASCAR had begun as a "stock" car operation in the literal sense that the first cars used were "showroom stock" with only minimal modifications.  That didn't last long, cheating was soon rife and in the interests of spectacle (ie higher speeds), certain "performance enhancements" were permitted although the rules were always intended to maintain the original spirit of using cars which were "close" to what was in the showroom.  The cheating didn't stop although the teams became more adept in its practice.  One Dodge typified the way manufactures used the homologation rule to effectively game the system.  The homologation rules (having to build and sell a minimum number of a certain model in that specification) had been intended to restrict the use of cars to “volume production” models available to the general public but in 1956 Dodge did a special run of what it called the D-500 (an allusion to the number built to be “legal”).  Finding a loophole in the interpretation of the word “option” the D-500 appeared in the showrooms with a 260-hp V8 and crossed-flag “500” emblems on the hoods (bonnet) and trunk (boot) lids, the model’s Dodge’s high-performance offering for the season.  However there was also the D-500-1 (or DASH-1) option, which made the car essentially a race-ready vehicle and one available as a two-door sedan, hardtop or convertible (the different bodies to ensure eligibility in NASCAR’s various competitions).  The D-500-1 was thought to produce around 285 hp from its special twin-four-barrel-carbureted version of the 315 cubic inch (5.2 litre) but more significant was the inclusion of heavy-duty suspension and braking components.  It was a successful endeavour and triggered both an arms race between the manufacturers and the ongoing battle with the NASCAR regulators who did not wish to see their series transformed into something conested only by specialized racing cars which bore only a superficial resemblance to the “showroom stock”.  By the 2020s, it’s obvious NASCAR surrendered to the inevitable but for decades, the battle raged.

1970 Plymouth Superbird (left) and 1969 Dodge Daytona (right) by Stephen Barlow on DeviantArt.  Despite the visual similarities, the aerodynamic enhancements  differed between the two, the Plymouth's nose-cone less pointed, the rear wing higher and with a greater rake.  It's a persistent myth the wing height was dictated by the need to ensure the trunk (boot) lid could be opened; the height a product of the point at which "clean" air, undisturbed by the car's progress, could be found while the two vertical struts improved directional stability while inducing minimal drag.     

By 1969 the NASCAR  regulators had fine-tuned their rules restricting engine power and mandating a minimum weight so manufacturers resorted to the then less policed field of aerodynamics, ushering what came to be known as the aero-cars.  Dodge made some modifications to their Charger which smoothed the air-flow, labelling it the Charger 500 in a nod to the NASCAR homologation rules which demanded 500 identical models for eligibility.  However, unlike the quite modest modifications which proved so successful for Ford’s Torino Talladega and Mercury’s Cyclone Spoiler, the 500 remained aerodynamically inferior and production ceased after 392 were built.  Subsequently, Dodge "solved" the problem of the missing 108 needed for homologation purposes by later introducing a different "Charger 500" which was just a trim level and nothing to do with competition but, honor apparently satisfied on both sides, NASCAR turned the same blind eye they used when it became clear Ford probably had bent the rules a bit with the Talladega.  Not discouraged by the aerodynamic setback, Dodge recruited engineers from Chrysler's aerospace & missile division (which was being shuttered because the Richard Nixon (1913-1994; US president 1969-1974) was taking the US towards détente with the US & USSR beginning their arms-reduction programmes) and quickly created the Daytona, adding to the 500 a protruding nosecone and high wing at the rear.  Successful on the track, this time the required 500 really were built, 503 coming of the line.  NASCAR responded by again moving the goalposts, requiring manufacturers to build at least one example of each vehicle for each of their dealers before homologation would be granted, something which typically would demand a run well into four figures.  Plymouth duly complied and for 1970 about 2000 Superbirds (NASCAR acknowledging 1920 although Chrysler insists there were 1,935) were delivered to dealers, an expensive exercise given they were said to be invoiced at below cost.  Now more unhappy than ever, NASCAR lawyered-up and drafted rules rendering the aero-cars uncompetitive and their brief era ended.

1968 Dodge Charger (left), 1968 Dodge Charger 500 (centre) and 1969 Dodge Charger Daytona (right).

Before the missile engineers got involved, the path to specific aerodynamic efficiencies had an element of trial and error.  Ascetically, the 1968 Dodge Charger (left) was visually a great improvement on its slab-sided predecessor (1966-1968) and the recessed grill with hidden headlights was much admired, as were the buttresses which at the back created what Chrysler dubbed the "tunnel roof".  However, although always intended for the NASCAR ovals, once used there at speed, the drivers found the grill functioned just like the parachute the shape resembled, increasing fuel consumption and lowering top speed while the tunnel roof created buffering, causing instability.  Above 150 mph (240 km/h), the 1968 Charger not only didn't work very well but was dangerous.  That same year, the Charger 500 (centre) appeared with the recessed grill replaced by what was close to a flat surface which to some extent ameliorated the "parachute effect" but it was still not an ideal shape with which to penetrate the air while removing the buttresses smoothed things at the back which was good but at the now higher speeds, lift became a problem, something potentially more lethal even than the movement induced by the buffering.  The missile engineers' combination of the nosecone and big rear wing on the 1969 Dodge Daytona (right) solved all problems and on 24 March 1970, at Alabama's Talladega Superspeedway, a Charger 500 (DC-93) prepared by Chrysler Engineering to Daytona specifications (originally on the press fleet, it was a recovered stolen car!) set the then closed course lap record of 200.447 mph (322.5882 km/h).

Fully restored DC-93, the Dodge Charger 500 which in Daytona trim set the 200.447 mph (322.5882 km/h) at Talladega, March 1970.  The relationship between this thing and even the Daytonas sold to the public was an indication of how far NASCAR's definition of "stock car" had travelled since competition began in 1948.   

So extreme in appearance were the cars they proved at the time sometimes hard to sell and some were converted back to the standard specification by dealers anxious to get them out of the showroom.  Views changed over time and they're now much sought by collectors, the record price known price paid for a Superbird being US$1,650,000 for one of the 135 fitted with the 426 Street Hemi.  Despite the Superbirds having been produced in some four times the quantity of Daytonas, collectors indicate they're essentially interchangeable with the determinates of price (all else being equal) being determined by (1) engine specification (the Hemi-powered models the most desirable followed by the 6-BBL Plymouths (there were no Six-Pack Daytonas built) and then the 4 barrel 440s), (2) transmission (those with a manual gearbox attracting a premium) and (3) the combination of options, mileage, condition and originality.  Mapped on to that equation is the variable of who happens to be at an auction on any given day, something unpredictable.

No homologation issues: Here and there, between 1938-2003, Volkswagen produced 21,529,464 Beetles (officially the VW Type 1).

That was demonstrated in August 2024 when a highly optioned Daytona in the most desirable configuration achieved US$3.36 million at Mecum’s auction at Monterey, California.  The price was impressive but what attracted the interest of the amateur sociologists was the same Daytona in May 2022 sold for US$1.3 million when offered by Mecum at their auction held at the Indiana State Fairgrounds.  The US$1.3 million was at the time the highest price then paid for a Hemi Daytona (of the 503 Daytonas built, only 70 were fitted with the Hemi and of those, only 22 had the four-speed manual) and the increase in value by some 250% was obviously the result of something other than the inflation rate.  The consensus was that although the internet had made just about all markets inherently global, local factors can still influence both the buyer profile and their behaviour, especially in the hothouse environment of a live auction.  Those who frequent California’s central coast between Los Angeles and San Francisco include a demographic not typically found in the mid-west and among other distinguishing characteristics there are more rich folk, able to spend US$3.36 million on a half-century old car they’ll probably never drive.  That’s how the collector market now works.  

1969 Ford Mustang Boss 429.

Although sometimes difficult, NASCAR could however be helpful, scratching the back of those who scratched theirs.  For the Torino and Mercury Cyclone race cars, Ford was allowed to homologate their Boss 429 engine in a Mustang, a model not used in top-flight stock car racing.  Actually, NASCAR had been more helpful still, acceding to Ford's request to nudge the seven litre displacement limit from 427 to 430 cubic inches, just to accommodate the Boss 429.  There was a nice symmetry to that because in 1964, Ford had been responsible for the imposition of the 427 limit, set after NASCAR became aware the company had taken a car fitted with a 483 cubic inch (7.9 litre) engine to the Bonneville salt flats and set a number of international speed records.  The car used on the salt flats was one which NASCAR had banned from its ovals after it was found blatantly in violation of homologation rules related to bodywork so there was unlikely to be much leeway offered there.

1971 Ford Falcon GTHO Phase III.

Australian manufacturers were (mostly) honest in their homologation programmes, Ford’s GTHO, Chrysler’s R/T Charger and Holden’s L34 and A9X were produced in accordance both with the claimed volumes and technical specification.  However, although in total the numbers added-up, they weren't always so punctilious in the form the parts ended up in the hands of customers.  Ford's RPO83 (Regular Production Option #83) was a run late in 1973 of XA Falcon GTswhich included many of the special parts intended for the aborted 1972 GTHO Phase IV and although, on paper, that seemed to make the things eligible for use in competition, it transpired the actual specification of various RPO83 cars wasn't consistent and didn't always match the nominal parts list.  History has been generous however and generally it's conceded that in aggregate, the parts subject to the homologation rules appear to have been produced in the requisite number.  By some accounts, this included counting the four-wheel disk brakes used on the luxury Landau hardtops but CAMS (the Confederation of Australian Motor Sport, at the time the regulatory body) was in the mood to be accommodating.

Nibble

Nibble (pronounced nib-uhl)

(1) To bite off small bits of something; to eat food by biting off small pieces.

(2) To bite, eat, or chew gently and in small amounts (often in the form “nibbled at”); to take dainty or tentative (especially when unsure of the taste) bites; an act or instance of nibbling.

(3) A small morsel of food.

(4) Snack food (allways (sweet or savory) in the plural as “nibbles” and usually served with drinks).

(5) In fishing, a response by a fish to the bait on a line (technically, the feeling of the fish tasting the bait but not yet “hooked”).

(6) In many contexts, a preliminary positive response or reaction such as an “expression of interest” to a proposal.

(7)  Of an idea or suggestion, tentatively or cautiously to consider.

(8) In moments of intimacy, sexually to stimulate a partner by the (gentle) use of the teeth on body parts (usually extremities) such as toes, finger tips, nipples or ear lobes, a subset of fetishists using this caressing as a prelude to acts such as biting, scratching or spanking.

(9) In computing, a unit of memory equal to half a byte, or four bits.

1425–1475: From the late Middle English nebillen (to peck away at, to sample, to take small bites) and thought related to the Middle Low German nibbelen (to gnaw; to pick with the beak), thus the presumption by most etymologists the word is probably of Dutch or Low German origin and akin to the modern Low German nibbeln (to gnaw), the Middle Dutch knibbelen (to gnaw) (and the source of the Dutch knibbelen (to cavail, squabble)) the Dutch nibbelen (to nibble) and the Saterland Frisian nibje (to nibble).  The noun (an act of nibbling) developed from the verb and appeared in the 1650s, extended in the mid nineteenth century to describe plates of "small bites or morsels.  The verb nosh came into use in New York in 1957 in the sense of “to snack between meals and was from the Yiddish nashn (nibble), from the Middle High German naschen, from the Old High German hnascon & nascon (to nibble), from the Proto-Germanic naskon & gnaskon.  The forms noshed & noshing soon emerged in casual use although “the nosh” had been used in the US military as a noun since 1917, meaning “a mess or canteen”; it was a clipping of “nosh-house” which in civilian slang described restaurants & cafés.  Nibble is a noun & verb, nibbled is a verb & adjective, nibbler is a noun, nibbling is a noun & verb and nibbleable & nibbly & nibblish are adjectives (although not all dictionaries list them as standard forms); the noun plural is nibbles.

Nibbles could also be described as tidbits (often wrongly used as titbits), bites, tastes, or crumbs.  In idiomatic use, “to get a nibble” is (analogous with a fish tentatively tasting the bait before swallowing the hook) to receive a response to an offer, suggestion, idea, advertisement etc.  “To nibble away at” describes processes similar to those illustrated by phrases such as “straw which broke the camel’s back” or “death of a thousand cuts”.  Rust for example “nibbles away” at metal and inflation “nibbles away” at savings and the value of money (unlike hyperinflation which, depending on the its extent, is better described as a process of erosion, decimation, destruction etc).  As a verb to nibble is also to find petty faults or make needlessly pedantic points.

Lindsay Lohan nibbling on a slice of watermelon.

In computing, a nibble was a unit of memory equal to half a byte, or four bits, it’s origin apparently in the late 1950s among the IBM engineers developing the mainframe architecture for the System 360 (the S/360, 1964), the fundamentals of which remain in use even now.  Engineers do have a sense of humor and “nibble” was chosen to represent half a byte, based on the homophony of byte and bite although more serious types (and there were a lot of them about at IBM) preferred half-byte or tetrade (“a group of four things”, from the Ancient Greek τετράς (tetrás)) and by the time the concept ended up in the hands of networking and communications engineers, it could also be a semi-octet, quartet or quadbit.  More linguistically adventurous types coined nybble as an alternative spelling (a tribute to the spelling of byte) and this encouraged others who developed a protocol for the exchange executed with four-bit packets which they labeled nabble, a nod to “babble”.  The word babble, despite the common belief, is unrelated to the Latin Babel, from Biblical Hebrew בָּבֶל‎ (bāḇel) (Babylon) and was from the Middle English babelen, from the Old English bæblian (which existed also as wæflian (foolishly to talk), from the Proto-West Germanic bablōn & wablōn, variants of babalōn, from the Proto-Germanic babalōną (to chatter), from a variety of primitive Indo-European sources which were various ways of expressing the idea of vague speech or mumbling, all of which etymologist suspect were onomatopoeic mimicking of the infantile sounds of babies, something forms appear in just about every known European language.

Lindsay Lohan at a table of nibbles.

In the early days of computing when memory of all types was expensive (and sometimes actually rare), nibbles were helpful because four-bit architecture was an economical way to implement processes and many of the early microprocessors, of which the Intel 4004 (1971) is probably the best remembered because it was the core of so many pocket calculators and despite the enormous advances during the last half-century, 4-bit microcontrollers remain in use, simply because something like a basic washing machine demands nothing more.  The programmers of the early mainframes were demanding more but the hardware to handle that didn’t then exist and the nibble was the optimal way to ensure the most characters could be contained in a given number of bytes, making computations faster and debugging easier although, in a classic work-around, some “nibbles” did grow to 8 bits, the trick invoked to add functionality while maintaining backward computability but the increasing muscularity of hardware soon rendered the approach obsolete.

The noun nibbler means (1) someone who nibbles, (2) a tool for cutting sheet metal and (3) a fish of the sea chub subfamily Girellinae and (4) a technique for duplicating copying protected floppy diskettes.  Copy-protected diskettes were common in the 1980s and were an attempt by software developers to prevent privacy.  When programs were distributed in a multi-diskette pack, it was common practice to have copy protection applied to only one, this being the one required to undertake an installation or make the software operative; it was essentially the same idea as “product activation” in the internet age.  As an additional layer, some manufacturers would include a counter on an installation diskette which would permit the product to be installed only a set number of times.  The idea behind the name was that the hacks “nibbled away” at the security layer(s) and examples included CopyIIPC & CopyIIAT (for low & double (160-180-320-360-720 kB) & high (1.2-1.44 MB) density diskettes respectively and Fast Hack 'Em.  It was something of a power race because within hours of Microsoft introducing a proprietary 1.7 MB format in an attempt to defeat the pirates, hacks & cracks appeared on the bulletin boards.

Joe Biden "nibbling" and a fish nibbling on the dead skin cells of feet. 

In July 2023, Joe Biden (b 1942; US president since 2021) was observed at a public event “nibbling” on the jumpsuit of an infant girl being held in her moth’s arms.  Fox News, on the spot to record the nibble, claimed the unfortunate child was “scared” and while that may or may not be true, she certainly seemed not best pleased.  Fox News though were right that it was definitely a nibble and nibblin’ Joe used exactly the same action as the small (and presumably grateful) fish which live out their lives feasting on the dead skin cells of the feet of folk who pay a small sum to sit for a while and be nibbled.  For fish and us, it's a win-win situation.

Joe Biden and his wife Dr Jill Biden (b 1951) at a campaign stop, Council Bluffs, Iowa, 30 November, 2019.

Nibblin’ Joe had of course been seen before, photos of him enjoying his wife’s fingers circulating in December 2019 at the start of his No Malarkey bus tour laying out the groundwork for his campaign in the Democratic Party’s Iowa presidential caucuses the following February.  Whether the sight of him nibbling her fingers was responsible for his poor showing in the caucuses isn’t known but despite Pete Buttigieg (b 1982) gaining twice his support in Iowa, the nomination for 2020 was ultimately secured by Mr Biden (with the odd nudge from the Democratic National Committee (DNC) which had decided they’d prefer to contest an election with someone who possibly was senile than with anyone who definitely was gay).

He was of course well known for being sniffin’ Joe, photographs of him leaning in, apparently to “sniff” the hair of women and girls (some young enough to be his great-granddaughters) circulating widely in the run-up to the 2020 election.  It was all very strange because it was such unusual behavior.  Had photographs appeared of a man of his age doing such things behind closed doors, it would have been a textbook case of public moral outrage but do so in public, knowing press and television cameras were focused on him and that sometimes the parents of the children were present, suggested a naïve innocence rather than anything distasteful.  Still, it was strange enough for the party hierarchy to discuss the matter with him and in a public statement, he acknowledged “things have changed” over the years and such tactility was no longer acceptable.  “I get it” he said.  Given the obvious discomfort displayed by some of the women sniffed, one might have thought he should have “got it” sooner.

Joe Biden and crooked Hillary Clinton, Scranton Airport, Pennsylvania, July 2016.

He’s also huggin’ Joe.  In July 2016, the greatest interest crooked Hillary Clinton (then in peak pantsuit mode) had in Joe Biden was thinking of some way he could be persuaded to serve as her secretary of state (foreign minister) once she’d enjoyed her landslide victory over Donald Trump (b 1946; US president 2017-2021).  That may have accounted for the warmth of the welcome she offered when she waited at the bottom of the stairs to meet him at Scranton airport, Pennsylvania.  However, perhaps overcome with emotion (Scranton his childhood home), the hug she offered lingered longer than she would have liked, huggin’ Joe hanging on for some fifty seconds despite her twice “tapping out” (a double tap on the arm, the accepted non-verbal code to indicate a release is requested) and even trying to wriggle free from his grasp didn’t work.

Should the 2024 US presidential contest descend again to Biden vs Trump (something a majority of Americans seem resigned to rather than enthusiastic about), Mr Trump will again have to decide which moniker best suits his opponent.  In 2020 he used “sleepy Joe”, the unsubtle message denoting someone in advanced cognitive decline who was apt to need frequently to nap.  At the time, there were memes around the hair sniffing photographs using “creepy Joe” and it may have been tempting but Mr Trump’s own documented history of ungentlemanly conduct with women may have led his advisors to suggest he avoid casting that stone.  On that basis, “sniffin’ Joe”, “huggin’ Joe” and “nibblin Joe” are probably out too so it’s either stick with “sleepy Joe” or think of something new.  Whatever his flaws, Mr Trump has a good record of avoiding issues with narcotics and alcohol so the well publicized problems of Hunter Biden (b 1970) might offer some possibilities given the recent discovery of cocaine in the White House although there’s said to be no evidence linking the substance with any member of the Biden family.  In the run-up to the 2020 election he’d used “Basement Biden”, “Beijing Biden” & “Slow Joe” but none really captured the imagination in the way of “crooked Hillary”, “low energy Jeb”, “little Marco”, “mini Mike”, “Lying Ted” or “Fauxcahontas” (although the last one was coined by someone else and Mr Trump usually preferred “Pocahontas”).  He does of course have other matters to think about but the task will have been allocated to staff and it’ll be interesting to see if they conjure up anything fun.

Errant & Arrant

Errant (pronounced er-uhnt)

(1) Deviating from the regular or proper course; erring; straying outside established limits (often used in sport as “errant shot”, “errant punch” etc).

(2) Prone to error; misbehaved; moving in an aimless or lightly changing manner (often used in a non-human context: breezes, water-flows etc).

(3) Journeying or traveling, as a medieval knight in quest of adventure; roving adventurously (archaic, although it may in this sense still be a literary device).

(4) Utter, complete (obsolete, the meaning now served by “arrant”).

1300–1350: From the Middle English erraunt (traveling, roving), from the Anglo-Norman erraunt, from the Middle French, from the Old French errant, present participle of errer & edrer (to travel or wander), from the unattested Vulgar Latin iterāre (to journey) (and influenced by the Classical Latin errāre (to err)), from the Late Latin itinerārī, a derivative of iter (stem itiner-) (journey) and source of the modern English itinerary), from the root of ire (to go), from the primitive Indo-European root ei- (to go).  Understandably, in the Medieval era, the word was often confused with the Middle French errant (present participle of errer (to err)) so the use in old translations need to be read with care and the Old French errant in its two senses (1) the present participle of errer (to travel or wander) & (2) past participle of errer were often confused even before entering English.  In any event, much of the latter sense went with arrant (which was once a doublet of errant).  All the muddle is attributable to the link between the Old French errant with the Latin errāns, errāntem & errāre (to err) and the present participle of errer (to wander), which was from the Classical Latin iterō (I travel; I voyage) rather than errō, which is the ancestor of the etymology of error (to err; to make an error).  The comparative is more errant and the superlative most errant and the synonyms (depending on context) include aberrant, erratic, offending, stray, unorthodox, wayward, deviating, devious, drifting, errable, fallible, heretic, meandering, misbehaving, mischievous, miscreant, naughty, rambling, ranging & roaming.  The obsolete alternative spelling was erraunt.  Errant is a noun & adjective (often postpositive) and errantly is an adverb; the noun plural is errants.

Arrant (pronounced ar-uhnt)

(1) Downright; thorough-going; flagrant, utter, unmitigated; notorious (the latter in the non-derogatory sense).

(2) Wandering; errant (obsolete).

1350–1400: From the Middle English, a variant of errant (wandering, vagabond), the sense developed from its frequent use in phrases like “arrant thief” which became synonymous with “notorious thief”.  Etymologists tracking the late fourteenth century shift note that as a variant of errant, it was first merely derogatory in the sense of “a wandering vagrant” and remembered as an intensifier due to its use as an epithet because of poetic phrases such as “arrant thieves and arrant knaves” (ie “wandering bandits”).  In the 1500s the word gradually shed its opprobrious force and acquiring the meaning “thorough-going, downright and notorious (the latter in the non-derogatory sense)”.  In a limited number of specific uses, arrant can still convey a negative sense such as “arrant nonsense!” (utterly untrue) and the meaning is preserved when Shakespeare’s “arrant knaves” (from the nunnery scene in Hamlet, Act 3, Scene 1) is invoked.  Remarkably, there are still dictionaries which list arrant simply as an alternative form of errant, despite in practice use having separated centuries earlier and some style guides suggest arrant should be avoided because (1) some may confuse it with errant and (2) it’s an adjective which seems used mostly in clichés.  The obsolete alternative spelling was arraunt, the obsolete comparative was arranter and the obsolete superlative, arrantest.  Arrant is an adjective and arrantly an adverb.

Swirl

Swirl (pronounced swurl)

(1) A twist, as of hair around the head or of trimming on a hat; a whorl or curl.

(2) Any curving, twisting line, shape, or form.

(3) A descriptor of a state or confusion or disorder.

(4) A swirling movement; whirl; eddy; to turn or cause to turn in a twisting spinning fashion (used especially of running water).

(5) In fishing, the upward rushing of a fish through the water to take the bait.

(6) To move around or along with a whirling motion; a whirl; an eddy.

(7) To feel dizzy or giddy (the idea of a “spinning head”).

(8) To cause to whirl; twist.

(9) To be arranged in a twist, spiral or whorl.

(10) Figuratively, to circulate, especially in a social situation.

(11) In AAVE (African-American Vernacular English), to in some way mingle interracially (dating, sex, marriage etc) (dated; now rare).

(12) In internal combustion engines (ICE), as “swirl chamber”, a now generic term for a type of combustion chamber design.

1375-1425: From the late (northern) Middle English swirlen (to eddy, swirl) which was probably from the Old Norse svirla (to swirl), a frequentative form of Old Norse sverra (to swing, twirl).  It was cognate with the Scots swirl & sworl (to eddy, swirl), the Norwegian Nynorsk svirla (to whirl around; swirl), the Swedish sorla (to murmur, buzz) and the Dutch zwirrelen (to swirl).  Related forms included the dialectal German schwirrlen (to totter), the West Frisian swiere (to reel, whirl), the Dutch zwieren (to reel, swing around), the German Low German swirren (to whizz, whirl or buzz around), the German schwirren (to whirr, whizz, buzz), the Swedish svirra (to whirr about, buzz, hum), the Danish svirre (to whizz, whirr) and the English swarm.  The construct may be understood as the Germanic root swir- + -l- (the frequentative suffix).  Swirl is a noun & verb, swirled is a verb & adjective, swirling is a noun, verb & adjective, swirly is a noun & adjective, swirler is a noun and swirlingly is an adverb; the noun plural is swirls.

In English, the late (northern) Middle English noun swirlen (to eddy, swirl) seems originally to have come from a Scottish word, the origin of which is undocumented but etymologists seem convinced of the Scandinavian links.  The sense of a “whirling movement” emerged in the early nineteenth century although the meaning “a twist or convolution (in hair, the grain of wood etc)” was in use by 1786.  The verb as a transitive in the sense of “give a swirling or eddying motion to” was in use in the early sixteenth century but it may by then long have been in oral use, one text from the fourteenth containing an example and the source of that may have been either Germanic (such as the Dutch zwirrelen (to swirl) or the Norwegian Nynorsk svirla (to whirl around; swirl) or it may have evolved from the English noun.  The intransitive sense (have a whirling motion, form or whirl in eddies) dates from 1755.  The adjective swirly existed by 1785 in the sense of “twisted or knotty” but by the middle of the next century it had come also to describe anything “whirling or eddying”, applied especially to anything aquatic.  By 1912, it was used also to mean “full of contortions or twists” although “swirling” in this sense had by then been in (gradually increasing) use for a century.

Of curls & swirls: Lindsay Lohan with curls (left) and swirls (right).

In hairdressing, although customers sometimes use the words “curl” and “swirl” interchangeably, to professionals the use should be distinct.  A swirl is a movement or pattern in which hair is styled or arranged, typically with a rounded or circular pattern and swirls can be natural (the pattern at the crown of the head where the hair grows in a circular direction) or stylized (the look deliberately created and most obvious in “up-dos) or the formal styles associated with weddings and such).  The end result is a wide vista and the swirl is more a concept than something which exists within defined parameters.  A curl is (1) a type of hair texture or (2) the act of creating a curl with techniques using tools and/or product.  Some people (and there’s a strong ethnic (ie genetic) association) naturally have curly hair due to the shape of their follicles and within the rubric of what used to be called the ulotrichous, hairdressers classify curls as tyree types: (1) tight (small, corkscrew-like structures), (2) medium (tighter curls but with a softer appearance) and (3) long spirals with a large diameter).  Some commercial product also lists “ringlets” as a type but as tight, well-defined spirals, they’re really a descriptive variation of the tight or medium.  So, the essential difference is that a swirl is a pattern or movement of the hair, while a curl describes texture or shape and while a swirl is a matter or arrangement, a curl demands changing the hair’s natural texture or shape.  Swirls are very much set-piece styles associated with formal events while curls are a popular way to add volume, texture, and movement to the hair.

In internal combustion engines (ICE), the “swirl chamber is a now generic term used to describe a widely-used type of combustion chamber when upon introduction, the fuel-air mixture “swirls around” prior to detonation.  The design is not new, Buick’s straight-8 “Fireball” cylinder head using a simple implementation as long ago as the 1920s and it would serve the corporation into the 1950s.  The critical aspect of the engineering was the interaction between a receded exhaust valve and a rising in the top of the piston which “pushed” most of the fuel-air mixture into what was a comparatively small chamber, producing what was then called a “high-swirl” effect, the “Fireball” moniker gained by virtue of the actual combustion “ball of fire” being smaller in volume than was typical at the time.  The benefit of the approach was two-fold: a reduction in fuel consumption because less was required per power-stroke and (2) a more consistent detonation of the poor quality fuel then in use.  As fuel improved in quality and compression ratios rose (two of the dominant trends of the post-war years), the attraction of swirl chambers diminished but the other great trend was the the effective reduction in the cost of gasoline (petrol) and as cars became larger & heavier and roads more suited to higher speeds, the quest was for power.

Swirling around: The swirl process in a diesel combustion chamber.

Power in those years usually was gained by increased displacement & combustion chamber designs optimized for flow; significantly too, many popular designs of combustion chamber (most notably those in the so-called “wedge” heads) were cheaper to produce and in those years, few gave much thought to air-pollution.  The cars of the 1950s & 1960s had really toxic exhaust emissions.  By the mid 1960s however, the problem of air pollution in US cities was so obvious and the health effects were beginning to be publicized, as was the contribution to all of this by motor vehicles.  Regulations began to appear, California in 1961 (because of the high vehicle population and certain geographical & climatic phenomena, Los Angeles & San Francisco were badly affected by air pollution) passing the first statute and the manufacturers quickly agreed to adopt this standard nationally, fearing other states might begin to impose more onerous laws.  Those however arrived by mid-decade and although there was specific no road-map, few had any doubts the rules would become stricter as the years passed.  The industry’s only consolation was that these laws would be federal legislation so they would need to offer only one specification for the whole country (although the time would come when California would decide things should be tougher and by the 1970s there were “Californian cars” and “49 state cars”).  K Street wasn’t the force then it later became and the manufacturers conformed with (relatively) little protest.

Fuel was still cheap and plentiful but interest in swirl chambers was revived by the promise of cleaner burning engines.  Because it wasn’t new technology, the research attracted little attention outside of the engineering community but in 1970, German-born Swiss engineer Michael May (b 1934) demonstrated a Ford (Cologne) Capri with his take on the swirl chamber in a special cylinder head.  In a nod to the Buick original, May nick-named his head design the “Fireball” (professional courtesy a thing among engineers).  What Herr May had done was add a small groove (essentially a channel surrounding the intake valve) to the chamber, meaning during the last faction of a second of piston movement, the already swirling fuel-air mixture got a final nudge in the right direction: instead of there being a randomness to the turbulence of the mix, the shape was controlled and was thus able to be lower in volume (a smaller fireball) and precisely controlled at the point at which the spark triggered detonation; May called this a “higher swirl”.  Not only did this reduce exhaust emissions but it also cut fuel consumption for a given state of tune so designers could choose their desired path: more power for the same fuel consumption or the same power for less and within a short time, just about the whole world was taking great interest in fuel consumption.

Detail of the original "flathead" cylinder head of the Jaguar V12 (left) and the later "Fireball" head with swirl chambers (right).

A noted use of May’s design was its adoption in 1981 on Jaguar’s infamously thirsty V12 (1971-1997), an innovation celebrated by the addition of the HE (High Efficiency) label for the revised power-plant.  The notion of “high efficiency” was comparative rather than absolute and the V12 remained by most standards a thirsty beast but the improvement could be in the order of 40% (depending on conditions) and it was little worse than the similar displacement Mercedes-Benz V8s of the era which could match the Jaguar for power but not the turbine-like smoothness.  Threatened with axing due to its profligate ways, the swirl chambers saved the V12 and it survived another sixteen years which included two severe recessions.  Debuting even before the Watergate scandal, it lasted until the Monica Lewinsky affair.  In the decades since, computer simulations and high-speed photography have further enhanced the behavior of swirl & turbulence, the small fireballs now contained in the center of the chamber, prevent heat from radiating to the surrounding surfaces, ensuring the energy (heat) is expended on pushing the piston down to being the next cycle, not wasting it by heating metal.  The system is popular also in diesel engines.
