Sqound

Sqound (pronounced skwu-kuhl)

An object in the shape of a square with rounded corners.

1990s: The word was coined by a person or persons unknown to distinguish between the (round) taillights used on (most) C4 Chevrolet Corvettes between 1983-1989 and those built subsequently (1990-1996), the construct being sq(uare) + (r)ound).  Square was from the Middle English square, sqware & squyre, from the Old French esquarre & esquerre, (which endures in modern French as équerre), from the Vulgar Latin exquadra, the construct being ex- (the prefix used as an intensive) +‎ quadro (four cornered; make square), from quadrus (square).  It displaced fēowerecge (four-edged).  Round was from the Middle English round & rounde, from the Old Northern French roünt & rund & the Old French ront, runt & reont (which endures in modern French as rond), from the Late Latin retundus & the Classical Latin rotundus.  The noun developed partly from the adjective and partly from the corresponding French noun rond.  Sqound is a noun & adjective; the noun plural is sounds.

Perhaps the ultimate “niche word”, the only known use is among members of the “C4 ‘Vette cult” (those devoted to the fourth series (C4) Chevrolet Corvette, 1984-1996).  It seems first to have been used as an adjective to describe the then unique taillights fitted to the Corvette ZR1 (1990-1995), released at the 1989 Geneva Motor Show.  Although an obvious visual clue, the ZR1 attracted most attention by it’s used of an all-aluminium, 350 cubic inch (5.7 litre) V8 which featured double overhead camshafts (DOHC) and 32 valve heads.  Although the 350 cubic inch displacement was shared with the mainstream small-block Chevrolet V8s, so different was it in terms of construction and internal dimensions that the Corvette community (a priesthood with very firm views) regard it as something separate from the long-running (1954-2002) small-block V8 family.  The engine was a co-development between Chevrolet and the UK-based Lotus Group which General Motors (GM, Chevrolet’s parent corporation) had acquired in 1986 (maintaining ownership until 1993) and was intended for use in a Corvette which could be marketed as the “world's fastest production car” (GM defining what constituted “production”); the V8 was given the internal designation LT5.  Although in the mid-1980s electronic engine management systems were still in their infancy, the LT5 did feature some genuine innovations in its fuel management, enabling the combustion chamber design to be optimized for power without this imposing the usual compromises in drivability at lower speeds.  Assembly of the LT5 was sub-contracted to Mercury Marine.

Perhaps of greater significance to GM was the expertise Lotus possessed in chassis design & tuning although the Corvette was a very different machine to the smaller, lighter cars with which Lotus had built their reputation, encapsulated by the philosophy of company founder Colin Chapman (1928–1982): “Simplify, then add lightness”.  Historically, that idea was most “un-Corvette” like and despite the aluminium engine block and heads, the ZR1 did emerge from development weighing some 200 lb (91 kg) more than the typical C4 Corvette, the additional heft the consequence of heavier components need to support the greater speed and lateral forces made possible by the additional power.  On the road, the Lotus influence was certainly felt, the ZR1’s limits of adhesion as impressive as the then impressively wide (315-35 x 17 inch) tyres would suggest.  Befitting its role, the ZR1 was offered only as a coupé with a removable roof panel (no convertibles were produced) and as well as the wider wheels, it was distinguished from the rest of the range by a widened tail section with a rear fascia housing four “squond” taillights, the first time since the 1961 models anything but four round units had appeared on a production Corvette.

The ZR1 was much admired although not all approved of the squonds.  However, Chevrolet’s stylists must have liked them because in 1990 the convex fascia and squonds were standardized across the range, presumably pleasing the accountants who probably never saw the point of producing two different moldings which fulfilled the same function.  Why the C4 cultists settled on “sqound” isn’t known but it’s likely to have been something which just “came to someone” searching for a word to describe a shape which was neither quite round or square; within the cult there is (as far as in known), no “linguistics & etymology” committee.  In 1990, there was no world wide web and the internet was almost unknown outside of universities and places like the Pentagon so it wasn’t as if Google was there to answer the question.  Had search engines been available, it’s likely sqound might never have been coined because the word “quartic” quickly (as least as quickly as a 2400 kbit/s modem on a dial-up connection permitted) would have been discovered.

Once a technical term in the arcane world of algebra and thus known to only a few, quartic first gained a larger audience in 1973 when, to general derision, British Leyland (BL) released the Austin Allegro, complete with a steering wheel which was “not quite round and not quite square".  Explaining it was chosen to afford the diver greater leg-room and provide a better view of the instruments, BL revealed the shape was “quartic”.  The idea actually wasn’t novel, dating back decades and had been used on quite a few American cars during the early 1960s but for whatever reasons, the presence of one in the Allegro attracted little but criticism, something the rest of the vehicle would soon suffer.  BL also attracted the scorn of mathematicians who hastened to point out a quartic is “an algebraic equation or function of the fourth degree or a curve describing such an equation or function” insisting the correct description for a "square with rounded corners" is “squircle” (in algebraic geometry "a closed quartic curve having properties intermediate between those of a square and a circle"), the construct being squ(are) +c(ircle).  Few etymologists (and certainly no lexicographers) appear to have listed sqound as a "real" word but it's of interest because as a rare example in English of a word where a "q" is not followed by a "u"; such constructs do exist but usually in the cases where initialisms have become acronyms such as Qantas (Queensland and Northern Territory Aerial Services).  Such words do appear in English language texts but they tend to be foreign borrowings including (1) qat (or khat) (a plant native to East Africa and the Arabian Peninsula, often chewed for its stimulant effects), (2) qi (a term from Chinese philosophy referring to life force or energy), qibla (the direction Muslims face when praying (towards the Kaaba in Mecca)) and (4) qiviut (the soft under-wool of the musk-ox, valued when making warm clothing).  For a while, BL pretended to ignored the pedants but within a year replaced the wheel with a conventional circular design.  Whatever the name, variations of the shape have since become popular with high-end manufacturers, Ferrari, Aston-Martin, Lamborghini and others all pursuing non-circular themes and one is a feature of the latest (C8) mid-engined Chevrolet Corvette, in which, unlike the unfortunate Allegro, it's much admired.
