Alternate & Alternative

Alternate (pronounced awl-ter-neyt, or al-ter-neyt (adjective) or awl-ter-nit (noun).

(1) Repeatedly and regularly to interchange with one another in time or place; rotate (usually followed by with).

(2) To change back and forth between conditions, states, actions etc.

(3) To perform or do in succession or one after another.

(4) Being in a constant state of succession or rotation; interchanged repeatedly one for another.

(5) Reciprocal; mutual.

(6) Constituting an alternative (a historic sense in English, revived in US use (and not without controversy).

(7) In botany, placed singly at different heights on the axis, on each side in succession, or at definite angular distances from one another, as leaves; opposite to the intervals between other organs (petals alternate with sepals).

(8) In electric current, voltage etc, to reverse direction or sign at regular intervals, usually sinusoidally ((having the shape or characteristics of a sine wave)), the instantaneous value varying continuously.

(9) In mathematics, designating the members in a series, which regularly intervene between the members of another series, as the odd or even numbers of the numerals; every other; every second (eg 2, 4, 6, 8).

1505-1515: From the Latin alternō (take turns), from alternus (one after another, by turns), the construct being alter (other) + -rnus (a suffix forming adjective from the earlier -r̥inos from -(o)sinos, from -nus or from some -r- or -s- stem + -nus; metanalysis of this suffix led to its free use).  In classical Latin, alternātus was the past participle of alternāre.  Derived forms are the adverbs alternately & alternatingly, the noun alternateness and the adjective nonalternating.

Alternative (pronounced awl-tur-nuh-tiv, al-tur-nuh-tiv)

(1) A choice limited to one of two or more possibilities, as of things, propositions, or courses of action, the selection of which precludes any other possibility.

(2) One of the things, propositions, or courses of action that can be chosen.

(3) A possible or remaining course or choice.

(4) Affording a choice of two or more things, propositions, or courses of action (of two things, propositions, or courses) mutually exclusive so that if one is chosen the other must be rejected.

(5) Employing or following non-traditional or unconventional ideas, methods etc.; existing outside the establishment.

(6) In logic (of a proposition) asserting two or more choices, at least one of which is true.

1580–1590: The construct was alternat(e) + -ive (an adjective suffix signifying relating or belonging to).  The –ive suffix is from the Anglo-Norman -if (feminine -ive), from Latin -ivus. Until the fourteenth century all Middle English loanwords from Anglo-Norman ended in -if (compare actif, natif, sensitif, pensif etc) and, under the influence of literary Neolatin, both languages introduced the form -ive.  Those forms not yet replaced were subsequently changed to end in -y (compare hasty, from hastif, jolly, from jolif etc.).  Like the Latin suffix -io (genitive -ionis), Latin suffix -ivus is appended to the perfect passive participle to form an adjective of action.  Alternative was from the Middle French alternatif, from the Medieval Latin alternātīvus (alternating), from the participle stem of Latin alternō (interchange, alternate). Derived forms are the adverb alternatively, the nouns alternativeness & alternativity, the adjective quasi-alternative and the adverb quasi-alternatively.

Alternative Facts

The phrase “alternative facts” aroused interest when used in 2017 by Donald Trump’s (b 1946; US president 2017-2021) campaign strategist and counselor, Kellyanne Conway (b 1967; senior counselor to the president, 2017-2020).  Ms Conway used the words during a Meet the Press interview to describe the use of statistics quoted by Sean Spicer (b 1971; White House Press Secretary & Communications Director, 2017), numbers which, prima facie, seemed dubious.  The matter about which Spicer spoke was not a great affair of church or state; it was squabble about which president attracted the greater live audience to his inauguration, Barack Obama (b 1961; US president 2009-2017) in 2009 or Donald Trump in 2017.  All available evidence appeared to suggest Obama’s numbers were up to twice those of Trump and if Spicer hadn’t brought it up probably nobody else would have mentioned it but for Trump, who borrowed for his campaign so many of the techniques he’d learned from his career in reality television, viewer numbers were professional life and death.

Ms Conway sought later to clarify “alternative facts” by defining the phrase as "additional facts and alternative information" which, when deconstructed, probably did add a layer of nuance but really didn’t help.  Journalists, not a crew always entirely truthful, decided to help and called the phrase "Orwellian", provoking a spike on the search engines as folk sought out "doublethink" and "newspeak"; sales of George Orwell’s (1903–1950) Nineteen Eighty-Four (1949) said overnight to have risen several-dozen fold.  The relationship between the press and the Trump White House was never likely to be friendly but “alternative facts” meant things started badly almost from day one.  Noting journalists rarely seemed to show great energy in pursuing crooked Hillary Clinton’s evasiveness and casual relationship with truthfulness, the administration felt unfairly picked-upon.  Journalists thought “alternatives facts” was just too blatant, beyond spin and actually an expression of contempt; they knew politicians were going to lie but the lack of subtlety was just insulting.  Both sides made good cases.

Watching with amused detachment were those with as little trust in what was being reported as in those being reported.  Some observed that “alternative facts” in political discourse was little different from the arguments offered in court by prosecution and defense; law was a matter for the judge but questions of fact were for the jury and for centuries juries had been choosing between alternative facts.  This was not novel and in an era where the conduct of politics was as adversarial as what’s done in any courtroom, nor did it seem difficult.  It’s never been certain just who first said “the truth is so precious it deserves an escort of lies” but it sits well with many.

The difference

Sometimes expressed is the view that in the days before linguistic promiscuity overtook the land, "alternate" and "alternative" enjoyed quite distinct meanings.  If two things were described as alternate, it meant one came after another in a repetitive pattern; if red switches to black, then red, then black etc, red & black are said to be alternating.  If one has the choice between red & black, the two colors are alternatives.  If one declines coffee, one might be offered tea as an alternative. Thus alternate is where one comes after another and alternative is where one is the option opposed to the other.  That is for many the preferred position but in the sixteenth century the alternative did enjoy the sense pendants insist belongs properly only to alternate so there's history but in English, citing precedents from the sixteenth century to support the revival of some archaic use rarely impresses and the blurring of any distinction is just how the language evolves.  In the US alternate & alternative seem now widely accepted as synonyms and while that's perhaps unfortunate, confusion will presumably be rare because the meaning will usually be clear from the context in which the words appear.

The battle may be lost: The international reach of US English means alternate & alternative may in decades to come be universally regarded as synonyms.  

Beyond US shores, the process has already begun.  Both belong to a class of words which sound similar and have a not-unrelated meaning (like enormous and enormity) and the trend towards interchangeability in use appears usually to favor that which is phonetically preferred so alternate is more often heard.  It’s common now in much of the English-speaking world to hear an opposition leader described as the alternate rather than alternative prime minister, something which should be said only when describing alternating premierships such as those of Gladstone and Disraeli.  Where alternate & alternative went in the US the world may be destined to follow: the Oxford English Dictionary (OED) definitely blames the Americans but they would say that wouldn't they?

Hood

Hood (pronounced hood)

(1) A soft or flexible covering for the head and neck, either separate or attached to a cloak, coat and similar garments.

(2) Something resembling or suggestive of such a covering (especially in shape) and used in botany to describe certain petals or sepals.

(3) In North America and other places subject to that linguistic influence, the (usually) hinged, movable part of an automobile body covering the engine (the bonnet in the UK and most of the old British Empire).  Despite geographical spread, the phrase “under the hood” is now close to universal, referring to (1) the engine of an automobile & (2) by extension, the inner workings or technical aspects of anything (a computer’s specifications etc).

(4) In the UK and most of the old British Empire, the roof of a carriage or automobile, able to be lowered or removed (ie on a convertible, cabriolet, roadster, drophead coupé (DHC) et al).  In North America and other places subject to that linguistic influence such things tend variously to be called soft-tops or convertible tops.

(5) A metal cover or canopy for a stove, fitted usually with a ventilation system (a flue or extractor fan).

(6) In falconry, a cover for the entire head of a hawk or other bird, used when not in pursuit of game.

(7) On academic gowns, judicial robes etc, an ornamental ruffle or fold on the back of the shoulders (in ecclesiastical garments, and in cults such as the Freemasons, also used as a mark of one’s place in the hierarchy).

(8) In nautical use, as hooding ends, one of the endmost planks (or, one of the ends of the planks) in a ship’s bottom at bow or stern which fits into the stem and sternpost rabbets.  When fitted into a rabbet, these resemble a hood (covering).

(9) In zoology, a crest or band of color on the head of certain birds and other animals (such as the fold of skin on the head of a cobra, that covers or appears to cover the head or some similar part).

(10) In anatomy (the human hand), over the extensor digitorum, an expansion of the extensor tendon over the metacarpophalangeal joint (the extensor hood (dorsal hood or lateral hood).

(11) In colloquial use in palaeontology, the osseous or cartilaginous marginal extension behind the back of many dinosaurs (also known as the “frill”).

(12) As the suffix –hood, a native English suffix denoting state, condition, character, nature, etc, or a body of persons of a particular character or class, formerly used in the formation of nouns: childhood; likelihood; knighthood; priesthood and of lad appended as required (Twitterhood, Instahood etc, subsets of Twitterverse & Instaverse respectively).

(13) In slang, a clipping of hoodlum.

(14) In slang, a clipping of neighborhood, especially an urban neighborhood inhabited predominantly by African Americans of low socioeconomic status (a part of African American Vernacular English (AAVE) and adopted also by LatinX) although use in these communities does now transcend economic status.

(15) To furnish with or fit a hood; to cover with or as if with a hood.

(16) In medieval armor, a range of protective cloakings or coverings

Pre 900: From the Middle English hode, hod, hude, hudde & hoode (hoodes apparently the most common plural), from the Old English hōd, from the Proto-Germanic hōdaz, (related to the Old High German huot (hat), the Middle Dutch hoet and the Latin cassis helmet) and cognate with the Saterland Frisian Houd, the Old Frisian hōde, the West Frisian & Dutch hoed, the Proto-Iranian xawdaH (hat), the German Low German Hood and the German Hut (hat).  The Old English hād was cognate with German –heit and was a special use used to convey qualities such as order, quality, rank (the sense surviving academic, judicial & ecclesiastical garments).  The ultimate source is uncertain but most etymologists seem to support the primitive Indo-European kad & kadh (to cover).  Hood is modified as required (chemical hood, clitoral hood, un-hood, de-hood, fume hood, hood-shy, hood unit, hoodwink, range hood, riding hood etc) and something thought hood-shaped is sometimes described as cuculliform.  Hood is a noun & verb, hooded & hooding are verbs, hoodless hoodesque & hoodlike are adjectives; the noun plural is hoods.

Hooded: Lindsay Lohan in hoodie, JFK Airport, New York City, NYC April 2013. The bag is a Goyard Saint Louis Tote (coated canvas in black).

Hood as clipping of hoodlum (gangster, thug, criminal etc) dates from the late 1920s and would influence the later use of “hoodie” as a slur to refer to those wearing the garment of the same name, the inference being it was worn with nefarious intent (concealing identity, hiding from CCTV etc.  Hood as a clipping of neighborhood (originally especially an urban (inner-city) neighborhood inhabited predominantly by African Americans of low socio-economic status) dates from circa 1965 and became part of African American Vernacular English (AAVE) and was adopted also by LatinX) although use in all communities does now transcend economic status.  It was an alternative to ghetto (a word with a very different tradition) and encapsulated both the negative (crime, violence, poverty) & positive (group identity, sense of community) aspects of the low-income inner city experience.  Although a part of AAVE, it never formed part of Ebonics because its meaning was obvious and, to an extent, integrated into general US vernacular English.  The phrase “all good in the hood” is an example of the use of the clipping.

The verb hood in the sense of “to put a hood” & “to furnish with a hood” on dates from circa 1400 while although hooded & hooding aren’t attested until decades later, it’s possible the use emerged at much the same time.  The Old English hod was typically "a soft covering for the head" which extended usually over the back of the neck but only in some cases did it (permanently or ad-hoc) attach to some other garment.  The modern spelling emerged early in the fifteenth century and indicated a “long vowel” although that pronunciation is long extinct.  The word was picked up in medicine, botany & zoology in the seventeenth century while the use to describe the “foldable or removable covers on a carriage which protects the occupants from the elements” was documented since 1826 and that was used in a similar context by the manufacturers of prams and baby-carriages by at least 1866.  The meaning “hinged cover for an automobile engine” was in use in the US by 1905 while across the Atlantic, the British stuck to “bonnet”.  The fairy tale (some read it as a cautionary tale) Little Red Riding Hood (1729) was a translation of Charles Perrault's (1628-1703) Petit Chaperon Rouge which appeared in his book Contes du Temps Passé (Stories or Tales from Past Times (1697)).

The suffix -hood (a word-forming element meaning “state or condition of being”) was an evolution of the Old English -had (condition, quality, position) which was used to construct forms such as cildhad (childhood), preosthad (priesthood) & werhad (manhood); it was cognate with German –heit & -keit, the Dutch -heid, the Old Frisian & Old Saxon -hed, all from the Proto-Germanic haidus (manner, quality (literally “bright appearance”, from the primitive Indo-European skai & kai- (bright, shining) which was cognate with the Sanskrit ketu (brightness, appearance).  It was originally a free-standing word but in Modern English survives only in this suffix.

HMS Hood in March 1924.  The last battlecruiser built for the Royal Navy, it was 860 feet (262 metres) in length, displaced 47,000 tons and had a main armament of eight 15 inch (380 mm) guns.

HMS Hood (1918-1941) was a Royal Navy battlecruiser named after Admiral Samuel Hood, first Viscount (1724–1816), one of five admirals the family would provide.  Although the Battle of Jutland (1916) had exposed the inherent limitations of the battlecruiser concept and the particular flaws in the British designs, the building of the Hood anyway continued and the revisions made in the light of the Jutland experience in some way exacerbated the ship’s problems; weight was added without fully affording the additional protection required.  The Admiralty was aware of this and of the four battlecruisers of her class planned, Hood was the only one completed as the Navy embarked on a re-design but the naval disarmament agreed between the major powers in the aftermath of World War I (1914-1918) meant none were built (indeed no navy would launch a new battlecruiser until the 1980s and even then the notion was thought strange) and for almost two decades Hood remained the largest warship in the world.

Naval architecture, fire control ballistics and aviation had however moved on in those years and although the biggest warship afloat (the “Mighty Hood” in the public imagination), Hood was outmoded but as late as the early 1930s this mattered little because the prospect of war between the big powers seemed not only remote but absurd.  Hood is still thought one of the most elegant warships ever and it spent those years touring the empire and other foreign ports, her fine lines and apparent might impressing many although the Admiralty was well aware the days of Pax Britannica were over.  Much comment has been made about the design flaw which resulted in the Hood sinking in minutes after a shell from the German battleship Bismarck, fired from a range of some ten miles (16,000 m), penetrated the deck (some modern analysts contest this because of technical details relating to the angle of fire available to the German gunners), causing the magazine to explode, essentially splitting the hull in two.  In fairness to the Kriegsmarine (the German navy), it was a good shot but at that range, it was also lucky, that essential element in many a battle.

In structural linguistics, the term “Americanisms” is used to describe several sub-sets of innovations in English attributed to those (and their descendents) who settled in North America.  They include (1) spellings (color vs colour), most of which make more sense than the originals, (2) simplification of use (check used for cheque as well as its other meanings), (3) coinings (sockdolager (decisive blow or remark), a nineteenth century American original of contested origin) and (4) alternatives (suspenders vs braces).  Hood was one word where used differed in the US.  In the UK, the hood was the (traditionally leather but latterly a variety of fabrics) folding top which began life on horse-drawn carriages and later migrated to cars which eventually were, inter alia, called cabriolets, drophead coupés or roadsters.  In the US the same coachwork was used but there the folding tops came to be called “soft tops”, one reason being the hood was the (usually) hinged panel which covered the engine.  In the UK, that was called a bonnet (from the Middle English bonet, from the Middle French bonet (which endures as the Modern French bonnet), from the Old French bonet (material from which hats are made), from the Frankish bunni (that which is bound), from the Proto-Germanic bundiją (bundle), from the primitive Indo-European bend- (to tie).  The origins of the use of bonnet and hood as engine coverings were essentially the same: the words were in the nineteenth century both used on both sides of the Atlantic to describe cowls or coverings which protected machinery from the elements, impacts etc (the idea based on the familiar garments) and it was only chance that one use prevailed in one place and one in the other.  There were other differences too: what the British called the boot the Americans said was the trunk which on the early automobiles, like many of the stage coaches they replaced, indeed it was.

Unhinged: Not all hoods were hinged.  In 1969, some Plymouth Road Runners (left) and Dodge Super Bees (right) could be ordered with a lightweight, fibreglass hood held in place by four locking pins.  Known as the "lift-off hood", it need two conveniently to remove the thing so it wasn't the most practical option Detroit ever offered but to the target market, it was very cool.

1769: In the sense of a "pin passed through the eye of a rope, strap, or bolt to hold it in place" it’s of unknown origin but etymologists agree it’s of nautical origin (though not necessarily from the Royal Navy) thus the speculation that it’s a frequentative form of “tug” or “to tug” (in the sense of “to pull”), the evolution influenced by regional (or class-defined) pronunciations similar to tog.  The wall fastener was first sold in 1934 although the toggle bolt had been in use since 1994.  The term “toggle switch” was first used in 1938 although such devices had long been in use in the electrical industry and they were widely used in motor vehicles until outlawed by safety legislation in the 1960s.  In computing, toggle was first documented in 1979 when it referred to a keyboard combination which alternates the function between on & off (in the sense of switching between functions or states as opposed to on & off in the conventional sense).  The verb toggle dated from 1836 in the sense of “make secure with a toggle” and was a direct development from the noun.  In computing, the toggle function (“to toggle back and forth between different actions") was first described in 1982 when documenting the embryonic implementations of multi-tasking (then TSRs (terminate & stay resident programs).  Toggle is a noun, verb & adjective, toggled & toggling are verbs, toggler, toggery and (the rare) togglability are nouns and togglable (the alternative spelling is toggleable) is an adjective; the noun plural is toggles.  Use of the mysterious togglability (the quality of being togglable) seems to be restricted to computer operating systems to distinguish between that which can be switched between and that which is a stand-alone function which must be loaded & terminated.

The Jaguar E-Type (XKE) and the toggle switches

1964 Jaguar E-Type roadster (Open Two Seater (OTS) as the factory at the time described the body-style).

Jaguar’s E-Type (sometimes informally called XK-E or XKE in the US), launched at the now defunct Geneva Motor Show in 1961, was one of the more seductive shapes ever rendered in metal.  Enzo Ferrari (1898-1988) was at the show and part of E-Type folklore is he called it “the most beautiful car in the world”.  Whether those words ever passed his lips isn’t certain because the sources vary slightly in detail and il Commendatore apparently never confirmed or denied the sentiment but it’s easy to believe and to this day many agree.  If just looking at the thing was something visceral then driving one was more than usually tactile and over sixty years on, the appeal remains, even if some aspects in the early models (such as the seats which looked welcoming but frankly were uncomfortable and the rather agricultural (no synchromesh on first gear) Moss gearbox) were a little too tactile.

1961 Jaguar E-Type OTS (Open Two Seater, now usually called a "roadster") with toggle switches.  Ergonomically, the layout was not wholly successful but was an ascetic delight and the toggle switches are thought more sexy than the later rockers.  There are two different patterns for the aluminium panel and the one used on the very early cars is much prized; it has never been available as a re-production.  In 1963, as a running change (the factory bulletin indicating it was done to reduce glare) the panel changed to use a black vinyl covering.

Another feature of the early (1961-1967) cars admired both for their appearance and pleasure of operation touch was the centrally-located array of toggle switches which controlled functions such as lighting and windscreen wipers.  Even by the slight standards of the 1960s, ergonomically the arrangement wasn’t ideal but, sitting under the gauges, it was an elegant and impressive look the factory would retain across the range for more than a decade, the E-type using the layout until production ended in 1974 (and it endured on the low-volume Daimler DS420 limousine until 1992).  However, while the layout survived, the toggle switches did not, the protruding sharpness judged dangerous by the NHSB (the National Highway Safety Bureau (which in 1970 became the National Highway Traffic Safety Administration (NHTSA)) under the newly established US DOT (Department of Transportation), established by an act of Congress on 15 October 1966 and beginning operation on 1 April 1967) which, since the publication of Ralph Nader’s (b 1934) book Unsafe at any Speed (1965) had begun to write legislation which stipulated standards for automobile safety, this in parallel with the growing body of law designed to reduce emissions.

1973 Jaguar E-Type roadster with rocker switches.  On the roadsters, the far-right switch was un-labeled because it was functional only on the coupés where it activated the rear-window demister.  On the XJ sedans (which used the same switch assembly), it swapped the flow between the twin fuel tanks.  When the S2 XJ was released in 1973, the whole dashboard was revised, greatly improving the ergonomics but lacking the visual appeal.  

In 1968, the new wave of legislation came mostly from the US DOT so applied almost exclusively to vehicles sold in the US but such was the importance of that market it made little sense for Jaguar to continue to produce a separate line with toggle switches for sale in the rest of the word (RoW) so the decision was taken to standardize on the flatter, more rounded rocker switches.  At much the same time, other changes were made to ensure the E-Type on sale in 1968 would conform also to other new rules, the most obvious being the banning of the lovely covered headlights which necessitated their replacement with higher-mounted units in a scalloped housing.  In view of the extent of the changes required, it was decided to designate the updated cars as the “Series 2” (S2).  Despite the perceptions of some, now fuelled by internet posts and re-posts, by 1967, Jaguar, while not a mass-production operation along the lines of a computerized Detroit assembly line, had long since ceased to be a cottage industry and as a change was made in a model’s specification, except for specified batches, that was applied to all production after a certain date.  Despite the factory’s records documenting this, urban myths continue to circulate, stimulated by “unicorns” such as the handful of 3.8 litre Mark 2 sedans built after 1967 when the line was rationalized (as the 240 & 340) and restricted to the 2.4 & 3.4 litre XK-Six; those 3.8s were documented  “special orders” and not ad-hoc aberrations.  However, nothing in the era has resulted in as much misinformation as the specification of what came (unofficially) to be called the S1.25 & 1.5 E-Types, the most common myth being that before S2 production proper began, some cars left the factory with a sometimes unpredictable mix of S1 & S2 parts, this haphazardness accounted for by the expedient of “using up stock”.  In the industry, (even in computerized Detroit) the practice was not unknown but there’s now no doubt it never applied to the 1967 E-Types.  What notably attracts speculation is the phenomenon of “overlap”: a Jaguar might be found to include some “later” or “earlier” features than the build date and VIN (vehicle identification number) sugget should be fitted.  It's part of the charm of the breed and is thought to be the result of the recorded “build date” reflecting when a car passed the final quality control checks so one with an earlier chassis number could be returned for rectification, thus picking up what appears to be an “out-of-sequence” date.  

The pure lines of the S1 E-Type (top) were diluted, front and rear, by the need to comply with US safety legislation, the later S2's head & taillights more clunky.  The collector market slang for the later headlight treatment is "sugar scoop".

The process by which S1 evolved into S2 was transitional which is why the designations S1.25 & 1.5 became accepted; not used by the factory, they’re said to have been “invented” by JCNA (Jaguar Clubs of North America), the S1.25 run beginning on 11 January 1967 after production resumed following the Christmas holiday while the first 1.5s were built that August.  Although much is made in the collector community of the defining differences between the “pure” S1 and the “transitional” S1.25 & S1.5, that “purity” is nuanced because like many others, the E-Type was subject to constant product development with changes appearing from time to time.  Early in the model run, there were some obvious changes such as (1) the modification to the “flat floors” to provide more leg-room, (2) the integration of the bonnet (hood) louvers into the pressing, (3) the external bonnet (really a “clamshell”) release being replaced by an internal mechanism, (4) internal trim changes including the dashboard materials, the console and seats, (5) the replacement of the Moss gearbox with an all-synchromesh unit and (6) the 4.2 litre engine replacing the original 3.8.  Beyond those well-known landmarks, between 1965 and early 1967 there was also a wealth of barely detectable (except to experts of which there are quite a few) cosmetic changes and mechanical updates including: (1) the glass windshield washer bottle replaced with plastic container (March 1965), (2) the addition of an alternator shield (October 1965), (3) an enclosed brake and clutch pedal box (October 1965), (4) a hazard waring (4-way) flasher added to US market cars (November 1965), (5) sun-visors added to roadsters (February 1966), (6) instrument lighting changed from blue to green (March 1966), (7) the rubber boot at the base of the gear lever being replaced by a black Ambla gaiter; there were also detail changes to the gearbox cover and prop shift tunnel finisher (October 1966), (8) the material used for the under-dash panels was changed from Rexine-skinned aluminum to fiberboard (October 1966) and (8) a Girling clutch master cylinder replaced the Dunlop unit (December 1966).

After the headlight covers were legislated to extinction, the replacement apparatus on the E-Types came to be called “sugar scoops”, a term earlier used for the Volkswagens & Porsches sold in North America (NA) which had to be fitted with sealed-beam headlights because of protectionist rules designed for the benefit of US manufacturers.  The use of “sugar scoop” for the E-Type was appropriate because the visual link with the original utensil (which, in technical terms, is a "specialized spoon") was much more obvious than the more subtle hint seen on Volkswagens & Porsches.

A US market 1977 Porsche 911 (1964-1989), fitted with the front bumper assembly of a later 911 (964 (1989-1994)):  The original “sugar scoops” are seen on the left and the replacement Hella H4 lights are to the right (in RoW cars both H2 & H4 units were fitted).  The sugar scoop (centre) is Japanese, circa 1970s.  Sugar scoops are used to scoop sugar from a “sugar scuttle” whereas if one’s sugar is in a “sugar bowl”, a “sugar spoon” is used.  The difference between a “sugar spoon” and a “tea spoon” is the former has a deeper and usually more rounded bowl and most are supplied as part of a “tea set” or “tea service”, often with the same decorative elements.

Despite that myriad of modifications, all E-Types up to those informally dubbed 1.5 are S1s but the running changes can be of significance to restorers if the object is to emulate exactly the state in which a vehicle rolled off the production line; in events such as a concours d'elegance, judges can deduct points for even minor variations.  Things became more distinct when on 11 January 1967 the first E-Type destined for the US market was built without the covered headlights and this marked the beginning of the run of what would come to be known as the 1.25 although it wouldn’t be until June-July that year the open headlights became a universal fitting on all E-Types.  Unlike some cars where changes can be determined from the sequential VINs, the only way accurately to determine whether a 1967 E-Type built between January and July was fitted with covered or uncovered headlights is to authenticate the market for which it was built, those for NA using the uncovered fittings.  What this meant was an analysis of successive VINs will reveal on a given day there might have been a mix of cars with the the different headlight assemblies going down the production line.  Curiously, there were some 1968 E-Types built for Canada which included the triple SUs and while these included the interior changes mandated by US federal law, the Tex door mirror on the driver’s side wasn't fitted and the tail and side lights were a different specification.  From 1969, Canada aligned its regulations with those of the US so from that point on, the NA specification was standardized.

Between August-October 1967, the 1.5 began to evolve and that included the twin Zenith-Stromberg carburetors replacing the triple SUs (on NA cars), the substitution of ribbed camshaft covers, a higher mounting of the headlights (to meet minimum height requirements) and the adoption of rocker switches.  At this point, the teardrop tail lights remained, the most obvious external marker of the S2 being the chunky light below the rear bumper bar although, in the usual manner, updates continued, such as twin cooling fans (a good idea) and 1000-odd (the so-called "R2" run of cars, almost all of which are registered as 1971 models although some left the factory in 1970) E-Types gained a pair of "leaper" badges on the flanks, just behind the front wheel arches.  Unlike the centrally mounted steel leapers used on the saloons, the badge used on the flanks required two part numbers, one each for the left & right.  It seemed a pointless addition and just more clutter, as they were on the S1 (1968-1973) & S2 (1973-1979) XJs.

1971 S2 Jaguar E-Type (centre) from the "R2" run of 1000-odd with the leaper badges on the flanks.

So much did the clutter created by bigger bumpers, protuberant headlight assemblies, badges and side-marker lights detract from the lovely, sleek lines of the Series 1 cars, bolting a luggage rack to the boot (trunk) probably seemed no longer the disfigurement it would once have been.  The left-hand (left) and right-hand (right) badges, being directional, were different part numbers (BD35865 & BD35866 respectively) and those used on E-Types were silver on black.  There were also variants used on the XJs which were gold on black and some had the leaping feline at a slight slope, both matters of note for those wishing to restore to the challenging "factory original" standard.  

So it can be hard to follow without a flow chart but, because of some overlaps in the production process, the S1-to-S1.25-to-S1.5 transition wasn’t entirely lineal but none of this is mysterious because Jaguar’s Factory Service Bulletins (JFSB) have documented these “inconsistencies” (which were standard industrial practice).  For example, there were a certain 32 specific NA market vehicles fitted with the headlight covers which were built with serial numbers later than the first of the open headlight cars.  Not all E-Types built for NA in 1967 thus had the open headlights and a not insignificant number of those 1.25 spec vehicles have been retro-fitted with the covers.  Such is the appeal of the covered headlights that although the E-Type market is monitored by the originality police (the “matching numbers” crowd which have an extraordinary knowledge of things like “correct” hose clamps or screw heads), there seems to be much untypical forgiveness for “back-dating” headlights to the sleeker look and they're not unknown even on the later, and much different, S3 cars.

The lure of the headlight covers: 1973 E-Type with headlight covers subsequently added (left) and with the original "sugar scoops" (left).  These are US market cars with the additional "dagmars" appended to the bumperettes.  Even by 1973, thin whitewall tyres were still a popular option on US Jaguars and they remained available until the last were sold in 1975 but the wide whitewalls often supplied in the early 1960s had long fallen from favor.  Although the judges in the JCNA confederation are usually uncompromising members of the originality police, they make a rare exception in not deducting points from late-build E-Types (the so-called 1.25 & 1.5) which have been fitted with the headlight covers.  Although the covers never appeared on the S3 E-Types, their presence clearly doesn't dissuade buyers because the S3 pictured above (left), in February, 2021 sold at auction for US$230,000.  It was an exceptionally low-mileage example (8000-odd miles (13,000 km)) but even given that it represented an impressive premium. 

While the loss of the toggle switches, teardrop taillights and headlight covers was a cause of some lament, some other changes also induce pangs of regret.  The switch from three to two carburetors was necessitated by the emission control regulations; the claimed horsepower dropped from 265 to 246 and while not many took the original rating too seriously, there was a drop in performance, especially in the upper speed ranges.  One often less noticed change mandated by the DOT was the replacement of the “eared” knock-off hubs for the wire wheels (the E-Types only ever using a two-eared version although third-party items with three ears are available) with a more “pedestrian friendly” type which, bewilderingly, are now referred to as the “non-eared”, “curly”, “octagonal”, “smooth”, “federal” “safety” and “continental” knock offs.  Take your pick.  Buyers could also take their pick of whether their “improved” wire wheels (now incorporating a forged centre hub) were painted in matte silver or chromed although the JFSB did caution that because of the altered configuration of the spokes, the wheels were not interchangeable with the earlier type except as a complete set (ie five per car).  Available from 1 January 1968 (the effective date for many of DOT’s new rules), this was Jaguar’s last update of the wire wheels which, in a variety of forms, the company had been using since being founded in 1922 as the Swallow Sidecar Company.  Never offered on the biggest and heaviest of the post-war cars (the Mark VII, VIII, IX and X/420G) or the new XJ range, they were last used on the “overlap” Daimler saloons (250 & Sovereign) in 1969 although they remained an option for the E-Type until the last was built in 1974.  Although a handful of small-scale producers continued to offer wire wheels, their final appearance on the option lists of the UK industry’s volume models came in 1980 when the last MGB was built.

Norway’s Motorhistorisk Klubb Drammen (Historic Car Club of Drammen) from Buskerud county reported on an exhibition hosted on 2 July 2014 by the Norsk motorhistorisk museu (Norwegian Motor Historic Museum) in the village of Brund, the event honoring Lindsay Lohan’s (b 1986) 28^th birthday.  The S2 Jaguar E-Type was recently restored but it would require a detailed examination to determine the degree to which (note the triple carburetors) it remains in its original specification.  Given the location this may have been a RoW car but there’s a lively two-way trans-Atlantic trade in E-Types (many now restored in Poland) so it may originally have been sold in the US or Canada.

The “Shaguar” used in the three Austin Powers movies (1997, 1999 & 2002).

The Shaguar was a 1967 S1.5 E-Type which thus featured the combination of teardrop taillights, sugar scoop headlights and rocker switches and, being right-hand drive (RHD), it wasn't built for NA.  When the auction house published the photographs, the vibrant on-line Jaguar community did their analysis and concluded it was built in December 1967 as a 1968 model but was in far from original condition (beyond the obvious paint and Shaguar badge).  The dashboard included the earlier manual choke and the heater and vent controls appeared to be missing and while the side & turn lights were NA specification, the taillights were those used on RoW cars.  The tachometer was the one one fitted to S2 models and it was suspected this may have been swapped when the later, non-original engine with the twin Zenith-Stromberg carburetors was installed.  Over the decades, many E-Types have for one reason and another drifted far from their original build and usually this limits their appeal to collectors but at Mecum Auctions in January 2025, the Shaguar achieved US$880,000 (including 10% buyers premium), several times the typical sale price of a non-original S1.5 E-Type in the same condition, its history as a cinema prop clearly an attraction.

Pre 1000: From the Middle English buterflie, butturflye & boterflye, from the Old English butorflēoge, buttorflēoge & buterflēoge.  It was cognate with the Dutch botervlieg and the German Butterfliege (butterfly).  The construct was (with variations was butere (butter) +‎ fly.  Etymologists note alternative origins for the name.  Either (1) it was first applied to creatures with wings of a notably yellowish hue (perhaps the dominant or single species of the type in an area) or (2) as a response to the belief that butterflies ate milk and butter or (3) the first element may have originally been butor- (beater), a mutation of bēatan (to beat), a reference to the movement of the wings.  The idea of the fragile things as thieves of milk and butter is supported by similar instances in other European languages including the German Molkendieb (butterfly (literally “whey thief”) and the Low German Botterlicker (butterfly (literally butter-licker) & Bottervögel (butterfly (literally “butter-fowl”).  There was also the notion they excreted a butter-like substance, memorably expressed in the Dutch boterschijte (butterfly (literally “butter-shitter”).  Most memorable however is the explanation in the tales of the Brothers Grimm (die Brüder Grimm, Jacob (1785–1863) and Wilhelm (1786–1859)) in which witches disguised themselves as butterflies.  The early forms in Middle English superseded the non-native Middle English papilion (butterfly) borrowed from the Old French.  Butterfly is a noun & adjective, butterflied is a verb & adjective and butterflying is a verb.  The noun plural is butterflies.

Butter was from the Middle English buter & butter, from the Old English butere, from the Proto-West Germanic buterā, from the Latin būtȳrum, from the Ancient Greek βούτῡρον (boútūron) (cow cheese), the construct being βοῦς (boûs) (ox, cow) + τῡρός (tūrós) (cheese).  Fly was from the Middle English flye & flie, from the Old English flȳġe & fleoge (a fly, a winged insect), from the Proto-Germanic fleugǭ (a fly) & fleugon (flying insect), from the primitive Indo-European plewk- (to fly).  It was cognate with the Scots flee, the Saterland Frisian Fljooge, the German Low German Fleeg, the Danish flue, Norwegian Bokmål flue & Norwegian Nynorsk fluge, the Swedish fluga and the Icelandic fluga, the Old Saxon fleiga, the Old Norse fluga, the Middle Dutch vlieghe, the Dutch vlieg, the Old High German flioga and the German Fliege (fly (literally "the flying (insect))).  The Old English fleogende (flying) was from the primitive Indo-European root pleu- (to flow).

Social butterfly Lindsay Lohan in butterfly print swimsuit, Cannes, 2016.

Butterfly was applied first to people circa 1600, originally in reference to vain and gaudy attire, an allusion to often bright and varied colors of a butterfly's wings.  By 1806 it had become a class-based put-down referencing a transformation from a lower social class to something better, invoking the idea of progression from sluggish caterpillar to graceful butterfly (essentially a synonym for bounder).  The reference to flitting tendencies (from one interest, occupation etc) dates from 1873 and the social butterfly (one who moves effortlessly between social encounters and events) emerged in the 1920s.  The swimming stroke was first defined in 1935.  As a general descriptor (butterfly agave, butterfly ballot, butterfly fish, butterfly flower, butterfly plant, butterfly bomb, butterfly keyboard, butterfly chair, butterfly ray, butterfly shell et al), it’s applied wherever the resemblance to the open wings appears compelling.  In culture, the butterfly tends to be more admired than caterpillar which is an earlier stage of their development, the lovely creatures often appearing on fabrics used for clothing and furnishings.

Native to the forests of Central and South America, the Blue Morpho is one of the world’s largest butterflies. The wings are bright blue with lacy black edges, the result of light reflecting off microscopic scales on the back of their wings.  Lovely though the blue appears, it’s often not seen because the underside of this butterfly’s wing is a dull brown which provides a camouflage against predators.  When the wings are closed as the Blue Morpho sits on a tree, it blends in well.

Butterfly valves came into use in the late 1700s and have been popular since for their ease of manufacture, simplicity of operation and low maintenance.  The butterfly nut appeared in 1869 although in some markets it usually called the wing nut; interestingly, the similar fastener with a male thread is known as a wing screw or wing bolt but apparently never a butterfly screw or bolt, presumably because the delicate butterfly is thought emblematically female.  The phrase “Who breaks a butterfly upon a wheel?” is from Alexander Pope's (1688-1744) Epistle to Dr Arbuthnot" (1735).  The allusion is to "breaking on the wheel", a form of torture in which victims had their long bones broken by an iron bar while tied to a Catherine wheel, the idea a critique of excessive effort or deployment of resources to solve a simple problem; the less confronting phrase “sledgehammer to crack a nut” means the same thing.  The phrase “butterflies in the stomach” is a descriptive reference to the mild stomach spasms induced by anxiety and dates from 1908.  The butterfly effect is the most celebrated idea from (the somewhat misleadingly named) chaos theory, introduced in the 1972 paper Predictability: Does the Flap of a Butterfly's Wings in Brazil Set Off a Tornado in Texas? by US academic meteorologist Edward Lorenz (1917–2008).  Lorenz had developed the theory based on his observations in the early 1960s (in one of the earliest big-data models) that a tiny change in one variable (one of a dozen numbers representing atmospheric conditions) had an extraordinary effect upon long-term outcomes.

The use of the butterfly motif in industrial design in 1967 became a footnote in legal history in the trial of the boxers Rubin "Hurricane" Carter (1937–2014) & John Artis (1946-2021) for a triple murder committed at the Lafayette Bar and Grill in Paterson, New Jersey.  Evidence presented by the prosecution claimed that witness descriptions of the getaway car matched the hired car Carter was found driving in the vicinity of the Lafayette immediately after the killings, their statements even including a mention of the distinctive butterfly-shaped taillight chrome.  However, although a witness said the rear lights lit up across the back of the getaway car, the taillights on Carter's Dodge Polara, although there was certainly a butterfly chrome surround, lit up only at the edges; it was the more expensive Dodge Monaco which had the extended lights.  In the ever changing swirl of model names and trim levels which characterized the US industry during its golden age (1955-1973), in 1966 the Polara was Dodge’s entry-level full-size model, above which sat the higher-priced Polara 500, Monaco, and Monaco 500.  For some reason (and this was not unusual), the lineup’s nomenclature in Canada differed, being Polara, Polara 440, Polara 880, and Monaco.  In both markets however, it was only the Monaco which featured the extended tail lamps.

On a dark night, glimpsed by a traumatized witness for a second or two, that may have not been significant because tests did reveal the reflective silver finish on the Polara’s rear panel did indeed appear red at certain angles when the brake lights were activated but the distinction, along with a witness’s correction of this in the 1976 re-trial did lead some to suggest the police might have been coaching witnesses; “hardening the statement” in law enforcement lingo.  That actually aligned with the evidence provided by another witness and the prosecution would later suggest later suggested the confusion was caused by the defense misreading the court transcript.

Maria Callas (1923-1977), backstage after appearing as Madam Butterfly, Civic Opera House, Chicago, 17 November 1955.  Had Cio-Cio-San been this feisty, she'd have kept Pinkerton. 

Bud Daley’s famous AP (Associated Press) photograph of diva Maria Callas, still in her Cio-Cio-San’s kimono, caught her snarling at US Federal Marshal Stanley Pringle, one of eight process servers there to serve her with two summonses.  The image was shot just after she'd left the stage, following her third and final performance in Giacomo Puccini's (1858–1924) Madama Butterfly (Madam Butterfly, 1904) and appeared the next morning on the front page of the Chicago Sun-Times with the headline: “Not So Prim a Donna”.  The article reported her words as: “Chicago will hear about this!  I will not be sued!  I have the voice of an angel!  No man can sue me.”  It transpired however at least one man could sue, the action brought by one Edward “Eddy” Bagarozy, who claimed to be the singer’s agent, an assertion based on a contract dating from 1947; the plaintiff sought (1) specific performance of the contract and (2) in the alternative, damages of US$300,000 (depending on the metrics chosen, equivalent to between US$4-6 million in 2025).  As in many such matters, ultimately, things were settled out of court.

Butterfly doors are used on some high-performance cars and not wholly as a gimmick, the advantage being that in such usually low-slung vehicle, they do make entry and exit somewhat easier than scissor doors.  There’s even more functionally on certain competition cars because (1) they allow the carefully-crafted aerodynamics of the canopy to be preserved, (2) the driver can enter and leave the cockpit more quickly and (3) the design allows the structural integrity of the shell to be maximized.  Butterfly doors open upwards and outwards and in that they differ from scissor doors which are hinged to move only upwards, thus offering the possibility of a greater aperture while demanding more lateral clearance.  Exotic doors were seen in a handful of pre-war cars, none of which reached production, but it was the Mercedes-Benz 300SL (W194) race-car of 1952 which brought to public attention the idea car doors could be something different.  Such was the response that the factory used the gull-wing doors when, in 1954, the 300SL (W198) was offered in a road-going version although the engineering, like the concept, was not new, having before been used in both marine architecture and aircraft fuselages.  Similarly, the design elements which underlie butterfly and scissor doors can be found in buildings and machinery dating back in some cases centuries but of late, all have come most to be associated with exotic cars.

1967 Alfa Romeo 33 Stradale

Variations on the theme had appeared on the show circuit for some time before butterfly doors debuted on the Alfa Romeo 33 Stradale in 1967 which was much admired but it was thought the complexity of such things would limit their use to low volume runs such as the Stradale (of which only 18 were built) or one-off styling exercises such as the Alfa Romeo Carabo (1968) which used scissors.  However, scissor doors appeared on the prototype Lamborghini Countach (LP500) and, despite the doubts of some, were retained when the production version was released in 1974.  Since then, gull-wings (which open upward on a horizontal axis, hinged from the roof), scissors (which open upwards, rotating on a horizontal axis, hinged from the front), butterflies (which open upwards and outwards on an axis unaligned to the vertical or horizontal, hinged from the A (windscreen) pillar and dihedrals (scissors which move laterally while rotating ) have become common (relatively speaking) and designers seem intent on adding some new twist which seem sometimes to add no advantage but usually attract publicity (admittedly an advantage in the abstract), the most complex to date being the dihedral synchro helix doors which open forward, slide forward and rotate up.

Mercedes-Benz McLaren SLR Coupé & Roadster (top) and McLaren MP4-12C Coupé & Spider (bottom).

When Mercedes-Benz released the SLR McLaren (2003-2009), in an attempt to make explicit the link with the 300SL, they laid it on with a trowel, the phrase “gullwing doors” appearing in the factory’s original press release no less than seven times, just in case people didn’t get the message.  Nobody was fooled and they’ve always been called butterflies.  One clever piece of engineering was seen when the SLR roadster was released, those butterfly doors made possible by using hinge points along the rather than at the top.  McLaren used a variation of this idea when it released the McLaren MP4-12C (2011-2014), omitting the top hinge which allowed the use of frameless windows even on the roadster (spider).

IBM's 1995 ThinkPad 701.

IBM's ThinkPad 701 series was available during 1995 and was that year's biggest seller in its class, its distinctive feature the "butterfly" keyboard, a design in response to the obviously contradictory demands that laptops be smaller and lighter while still equipped with keyboards big enough comfortably to be used (especially with the big, clumsy fingers of men).  The 701 was marketed in what was then an untypically IBM manner, newspaper advertisements in the run-up to the launch published with nothing but a butterfly in the corner, the IBM logo later added while a few days before the debut, the text "Watch for the announcement" appeared.  Butterfly had actually been the project's internal codename although it had never been intended for use as a product, apparently because IBM's corporate policies didn't permit the use of the names of living.  Still, the use in the teaser advertisements did suggest they planned it to catch on as a nickname and doubtlessly hoped for a better outcome than the last time a codename was picked-up, the unfortunate "peanut" (the PCjr (1984-1985)) not fondly remembered.

IBM Thinkpad 701 commercial, 1995.

IBM's 1995 ThinkPad 701.

The 701 series was well-received and butterfly keyboard much admired.  By 1995, although it was clear to most of the industry that OS/2 (IBM's pre-emptive, multi-tasking operating system (OS)) was unlikely to achieve critical mass in either the consumer or corporate markets but the company continued to try to nudge things along: While the 701s using Intel’s i486 DX2 50/25 MHz CPU (central processing unit) came pre-installed with a combo PC-DOS 6.3 OS & Microsoft Windows 3.11 (Windows for Workgroups) operating environment, those using the i486 DX4 75/25 MHz chip offered the option of a dual-boot so users could choose either the combo or IBM’s OS/2 Warp (3.0).  The main body of the keyboard was a two-piece construction, which, gear-driven by the movement of the lid, spread apart to become a single unit as the laptop was opened, the process reversed as the lid closed.  IBM actually called it the TrackWrite, but it was universally known as the butterfly and so compelling was the design that to this day, one is on permanent display in Manhattan's Museum of Modern Art (MoMA).  Popular though it was, the market moved and the place on the demand curve at a price point which interested IBM was for laptops with larger screens so the need for the butterfly technology vanished, the 701 remaining unique.  Some patents have recently been filed which suggest manufacturers may be planning to release another laptop with a butterfly keyboard but, in an age of ultra-thin devices, it will presumably be a thing of low-tactility and thus lacking the responsiveness which had been one of the most attractive features of the original.

Thirty years after: 2025 Lenovo ThinkPad X1 Carbon Gen 13 (Lenovo part number 21NSCTO1WWAU8).

Although thinner and with many advances internally, at first glance a 2025 Lenovo ThinkPad appears little different from a 1955 (non-butterfly) IBM original.  Like the shark and pencil, the basic laptop design seems to have attained its evolutionary perfection.  Among the features carried over from IBM was the "TrackPoint" (the small, red pointing device in the centre of the keyboard), used to control the on-screen pointer.  IBM made a number of variants of the red rubber cap (“Classic Dome”, “Soft Dome”, “Soft Rim” and (most memorably) “Eraser Head”) but (male) programmers tended to call it “the clit”. 

A descendent of IBM ThinkPad, the original IBM PC-1 (August 1981) was the MRCA (most recent common ancestor) of both and, even now, a few ancient traits remain identifiable.  In 2005, IBM exited the PC (personal computer) and laptop business, selling the lines to Chinese manufacturer Lenovo, including as a transitional arrangement the right to use the IBM brand on the hardware for five years, the last so labelled thus made in 2010.  However, because the ThinkPad and ThinkCentre trademarks were part of the IP (intellectual property) Lenovo acquired, these continue to appear.  The deal in 2005 meant that IBM, which in 1981 had triggered the PC revolution with the release in August of the original PC-1, was no longer a part (although it continued to be active in software and server production) of the industry which (unintentionally) it had played such a part in creating and which transformed the modern world.  Nothing lasts forever.
