(2) A barb, or the barbed head, of a harpoon, spear, arrow etc (also called flue).

(3) A metal hook on the head of certain staff weapons (such as a bill), made in various forms depending on function, whether used for grappling or to penetrate armour when swung at an opponent.

(4) In metal casting, a wing-like formation on a central piece (similar to a spur and often a product of the vesting process to be filed off.

(10) In ichthyology, any of several American flounders of the genus Paralichthys, found in the Atlantic Ocean; used loosely, any of various other flatfishes (an often used an an alternative name for the flounder).

(11) Any parasitic flatworm (notably the blood fluke and liver fluke), of the classes Monogenea and Digenea (formerly united in a single class Trematoda (as trematodes)).

Pre 900: From the Middle English flok, fluke & flewke, from the Old English flōcand cognate with the Old Norse flōki; It may be compared with the and the Old High German flah (flat (source of the modern German flach)), from the Proto-Germanic flakaz although for technical reasons related to the phonetics, etymologists seem to prefer a link with the Middle Low German vlögel (wing) and Germanic vlōch & vlucht (used in the sense of both “wing” & “flight”) or even vlunke (the modern Low German Flunk (wing, pinion)).  The modern use in German of fluke to describe the tail of whales and such is thought to be borrowed from English.  The use of fish came from the Old English flōc (flatfish), of Germanic origin, related to the German flach (flat), the Old Saxon flaka (sole), the Old High German flah (smooth) and the Old Norse floke (flatfish, flounder, flak, floe; disk), all ultimately from Proto-Germanic flakaz, from the primitive Indo European root plak- (to be flat).  The parasitic worm was so named in the 1660s by virtue of the distinctive (flat) shape.  Fluke is a noun & verb, flukishness is a noun, fluking is a verb, fluked is a verb & adjective, flukeless, fulkesque, flukelike, flukier, flukish, fluky, flukier & flukiest are adjectives and flukily is an adverb; the noun plural is flukes (the plural fluke used of the fish; flukes used otherwise including of the flatworms).

Lawyer and feminist activist, Sandra Fluke (b 1981), Ms magazine, Vol XXII, No 2, Spring-Summer 2012.

The use to describe the components of anchors, harpoons and such dates from the mid-sixteenth century and is of obscure origin, most etymologists concluding it was adopted cognizant of the original sense of “flat”, the reference used originally of the flat, pointed end of a anchor and that may have been picked up either from fluke in the sense of “the flatfish” (based on the shape) or from the Low German flügel (wing).  What is certain is the anchor’s triangular fitting was transferred to the tails of whales (and later other cetaceans), that in use by at least 1725.  Fluke has been used in the sense of “a lucky stroke, a chance hit” only since 1857 (when it appeared in the press also as “flook” and the origin is obscure although most sources suggest it came from billiards.  The speculative theories include (1) a reference to a whale's use of flukes rapidly to propel themselves in the ocean, (2) a re-purposing of the contemporary sailors slang “going-a-flunking” (to sail quickly; to go fast) or (3) an English dialectal origin (in the sense of “a guess”).  The adjective fluky (depending on chance rather than skill (“pure ass” a modern form)) was in use by at least 1867.  The “fluke” usually is something “lucky or fortuitous” but there are also the idiomatic phrases “fluke out”, “flukes out”, “fluking out” & “fluked out” which is “to lose or fail due to a fluke; to deserve to win or succeed but instead lose due to a fluke, especially a last-minute or unpredictable fluke” and thus connected with the notion of “defeat from the jaws of victory”.  The “fluke up” (also as “flukes up”, “fluking up” & “fluked up”) is not dependent on the existence of a “fluke” (in any sense) but means “to mess up; to blunder; to fail” and is a polite form of “fuck up”.  The special coinings flukicide & flukicidal are used in relation to the killing of the parasitic fluke worms.

Being one of the industry’s notorious nictators, it was perhaps something not especially flukish when a paparazzo took a photograph of Lindsay Lohan winking but what was a fluke was the shot was perfect for a movie poster, the thought being the wink was a midliminal device which convey the message “you will have a marvellously good time if you watch this film” and the starlet must have agreed because for a while, the wink became her signature gesture.  According to the authoritative PosterWire, Ms Lohan sat for a photo shoot so promotional shots would be ready for the release (even wearing an auburn wig because she had by then entered her famous blonde phase) but the studio rejected what was offered because they were “too high style which was not the vibe of the film.”  Another photo session was scheduled but then someone remembered the paparazzi “winking shot”; not only did it become the poster but it also inspired the film’s tag line: “Everything changed in the wink of an eye.”  The shot used for Just My Luck (2006) was taken the previous year on Madison Avenue by New York Post photographer Larry Schwartzwald (1953-2021) who had the untypical background (among the paparazzi) of studying literature at New York University and, as he proved, “everything is text”.

The “blood shot” is destined to become one of the images of twenty-first US politics and while in many ways “perfect”, it’s really not a “fluke” because at that point, every photographer on site was snapping away and something similar was guaranteed to emerge.  Noting the injury was to Mr Trump’s right ear, some immediately dubbed the “bullet shot” the “In one ear and out the other” but it was a genuine fluke because if snapped a millisecond earlier or later, the “speeding bullet” would not have been in the frame; a “one in a million” (at least) shot and therefore flukish.

Syncategorematic

Syncategorematic (pronounced sin-kat-i-gawr-uh-mat-ik or sin-kat-i-gor-uh-mat-ik)

(1) In traditional logic, of or relating to a word that is part of a categorical proposition but is not a term, as all, some, is (applying to expressions not in any of Aristotle's categories, but form meaningful expressions together with them, such as conjunctions and adverbs).

(2) In contemporary logic, of or relating to a word or symbol that has no independent meaning and acquires meaning only in the context of other words or symbols, as the symbol (or the word of).

1820–1830: From the Late Latin syncatēgorēmat-, stem of syncatēgorēma (part of a discourse that needs another word to become fully intelligible).  The construct was syn- +‎ categorematic.  The syn- prefix (used also as syl- (if preceding a “l” and sym- (if preceding a “b”, “m” or “p”) was from the Ancient Greek συν- (sun-), from σύν (sún) (with, in company with, together with) and may be compare with the Sanskrit सम्- (sam-).  It was appended to create forms with the meanings (1) identical, (2) with, together, or (3) concomitant.  Categorematic was from the Ancient Greek κατηγορῆμα (katēgorēma) (predicate; or something that is affirmed) from the verb κατηγορέω (katēgoreō) (to accuse, assert, or predicate).  The Latinized version of this root (categorema) was adopted by English and was the source of the familiar word “category” (and derivatives).  With the mix of Greek and Latin influences, syncategorematic is one of those words the more fastidious purists dislike.

The suffix -ate was a word-forming element used in forming nouns from Latin words ending in -ātus, -āta, & -ātum (such as estate, primate & senate).  Those that came to English via French often began with -at, but an -e was added in the fifteenth century or later to indicate the long vowel.  It can also mark adjectives formed from Latin perfect passive participle suffixes of first conjugation verbs -ātus, -āta, & -ātum (such as desolate, moderate & separate).  Again, often they were adopted in Middle English with an –at suffix, the -e appended after circa 1400; a doublet of –ee.  The construct of the –atic suffix was –at(e) +‎ -ic; it was a doublet of –age and an alternative form of –tic.  The -ic suffix was from the Middle English -ik, from the Old French -ique, from the Latin -icus, from the primitive Indo-European -kos & -ḱos, formed with the i-stem suffix -i- and the adjectival suffix -kos & -ḱos.  The form existed also in the Ancient Greek as -ικός (-ikós), in Sanskrit as -इक (-ika) and the Old Church Slavonic as -ъкъ (-ŭkŭ); A doublet of -y.  In European languages, adding -kos to noun stems carried the meaning "characteristic of, like, typical, pertaining to" while on adjectival stems it acted emphatically; in English it's always been used to form adjectives from nouns with the meaning “of or pertaining to”.  A precise technical use exists in physical chemistry where it's used to denote certain chemical compounds in which a specified chemical element has a higher oxidation number than in the equivalent compound whose name ends in the suffix -ous; (eg sulphuric acid (H₂SO₄) has more oxygen atoms per molecule than sulphurous acid (H₂SO₃).  Used in linguistics (of a term), syncategorematic describes those terms which demand the appending of other terms to make a meaningful constituent of language; in th more arcane corners of the field, there are terms said to be (the comparative) “more syncategorematic” and (the superlative) most syncategorematic.  Syncategorematic & syncategorematical are adjectives, syncategoreme & syncategorematicity are nouns and syncategorematically is an adverb; the noun plural is syncategoremes or syncategorematicities (the latter apparently not in use).

Sentence: “The girl’s legs were under the table.”  The preposition “under” is syncategorematic because it describes the spatial relationship between her “legs” and the “table” but in isolation, “under” has no meaning.

It’s a long word and the definition might seem convoluted but in English syncategorematic words are in common, everyday use.  In traditional logic, it denotes a word unable to sustain useful meaning if standing alone but must be joined to a categorematic term in order to enter a categorical proposition; “some”, “and” & “all” are among those used most frequently.  In modern logic, the sense was extended to any symbol with no independent meaning.  Some terms which seem grammatically categorematic are often classed as syncategorematic, especially those which are in some way “value loaded” attributive adjectives (such as “good” or “large”).  Neither “good, nor “large” possess independent meaning whereas “red” and “is a Ferrari” are so vested; something can simply be “red” but it there is nothing which can be understood from “large” as a stand-alone term.  Meaning is attained only when something is added because the meaning comes from the sense of being relative-to-something (a “large bacterium” may be big enough to be the biggest bacterium ever seen but, comparatively, it’s nothing close to the size of a “large elephant”.

Sentence: “A girl is sitting on the floor.”  Both “a” and “the” are syncategorematic; they modify the nouns “girl” and “map” but do not, when standing alone, impart meaning.

The common examples of syncategorematic terms in English can be classified into a number of categories: (1) Logical Operators: (and, or, not, if, then) which structure logical relationships between propositions; (2) Articles: (the, a, an) which specify definiteness or indefiniteness but lack standalone meaning; (3) Prepositions: (in, on, at, by, with) which indicate relationships between nouns or pronouns but do not on their own impart meaning; (4) Conjunctions: (and, but, or, because) which connect clauses or ideas; (5) Quantifiers: (all, some, none, many, few) which express quantity or extent without referring to a specific entity; (6) Negations: (not, no) which modify the meaning of other terms or clauses and (7) Adverbs of Degree: (very, quite, somewhat, too) which modify adjectives or adverbs to indicate intensity or degree.

There are nuances in use such as the legendary exchange which gave language the word “laconic” (using few words; expressing much in few words).  In Antiquity, Laconia was the region inhabited and ruled by the Spartans, known for their brevity in speech and in English, the meaning “concise, abrupt” emerged in the 1580s (although laconical was created and went extinct a decade earlier).  The origin of this sense was when Philip II of Macedon (382–336 BC; king (basileus) of Macedonia 359-336) threatened the Spartans with the words: "If I enter Laconia, I will raze Sparta to the ground." to which the Spartans replied: "If.”  In that case, the meaning is derived from the context, a case in which “if” (usually syncategorematic) has meaning as a superficially single, stand-alone word.

Recto & Verso

Recto (pronounced rek-toh)

(1) A right-hand page of an open book or manuscript (almost always bearing the odd numbers); the front of a leaf.

(2) The front of a loose sheet of printed paper

1815–1825: A clipping of the Late Latin phrase rēctō foliō (on the right-hand (leaf or page)), ablative of the Latin rēctus (in this context “right”).  Recto is a noun; the noun plural is rectos.  The Latin rēctus (past participle of the verb “regere” (to rule; to guide; to straighten) and perfect passive participle of regō (to keep or lead straight, to guide)) was from the Proto-Italic rektos, corresponding to the primitive Indo-European hreǵtós (having moved in a straight line), from reǵ- (to move in a straight line; to direct).  It was used to mean “straight”, “upright” and “correct” as well as “right”.  In general use it was used in the sense of “right, correct, proper, appropriate, befitting with a particular emphasis on “morally right, correct, lawful, just, virtuous, noble, good, proper, honest”.  The association with “straightness” and “rightness” also influenced other derivatives in Latin and Romance languages, such as rectum (straight (and its use in anatomy)), rectitude (moral uprightness) and words in modern languages (rectify, direct et al).

Verso (pronounced vur-soh)

(1) A left-hand page of an open book or manuscript (almost always bearing the even numbers); the back of a leaf.

(2) The back of a loose sheet of printed paper.

(3) In numismatics, the side of a coin opposite to the obverse (the reverse)

1830–1840: A clipping of the New Latin phrase versō foliō (the leaf having been turned; the turned side of the leaf; on the turned leaf), the construct built with the Latin verb vertere (to turn; to revolve; to change) + folium (a leaf). 

Vertere ultimately was from the primitive Indo-European root wert- (to turn; to rotate).  Verso was the ablative form of versus (turned; facing; a line or verse in poetry, (originally meaning “a turning of the plow”), thus, as used in versō foliō , the reference was to the back (reverse) side of a page in a book or manuscript (as opposed to the recto (the front side).  The primitive Indo-European root wert- also provided the ultimate source of a number of related words in Indo-European languages, all of which is some way emphasize the concept of “turning” or “change”, the modern descendants including verse, invert, revert, and versatile, all of which preserve the idea of turning or changing orientation.  Verso is a noun; the noun plural is versos.

Recto is the front (right) and verso the back (left) side of a leaf of paper in something assembled permanently (ie bound or in some way joined permanently at the spine) in a book, codex or such.  The terms have always been used to refer to the finished article, not the material used in production.  This was not something of significance when books were assembled from single sheets which then were bound but in mechanical printing, it became common for larger sheets (the folium) to be printed with many pages, later to be folded (prior to binding) so the numbers on those larger sheets weren’t sequential when the page was flat but became so when folded.  Rēctō foliō (on the right side of the leaf) and versō foliō (on the back side of the leaf were thus created in the bindery, not by the scribe).  The use of the terms for loose leaf sheets came later.

Recto & Verso are sometimes referred to as part of the architecture or archeology of printing, correctly, they’re an aspect of codicology (the study of codices) and there is some academic dispute about the origins, the Australian historian Martyn Lyons (b 1946) suggesting the term rēctum (right, correct, proper) for the front side of a leaf was derived from the use of papyrus in late antiquity, based on a different grain running across each side with on one suitable for writing upon (the “correct”, smooth side).  In an echo of that, even modern paper has a “grain” (by virtue of the way the pulp is laid in the production process) and when using heavily textured bond paper, the most fastidious technicians ensure the stock is “laid” the “correct” way.  Recto and verso are reversed when language read right-to-left are used (so regardless of language, the verso is read first).  In publishing, the convention is for the first page of a book (page 1) to be a recto so almost all recto pages have odd numbers and all versos even numbers.

On-line editions of publications are not simply digital replications of the layout used in print where the recto-verso model remains in use.  The migration to screens has been cited as the prime reason the “two-page spread” is now less common in print.

With the coming of computers, pages came to be viewed on screens and as technology improved, it became possible to display two pages, side-by-side, thereby permitting publications such as pictorial magazines to maintain the recto-verso model and for readers to consume the content presented in the same visual format as the printed edition.  However, the screens of eBook readers, smartphones and tablets have a smaller surface area than the typical computer monitor and tend to be optimized for single-page display (although may do have a two-page option).  For that reason, publications which maintain both traditional print editions and on-line versions, have been compelled to create a different visual model for each format (there can be several) because the old “two-page spread” simply doesn’t work was well, viewed a page at a time.  The layout of on-line content is not simply a replication of a print edition (which follows the classic recto-verso model) and it seems clear the small has had a great influence on the large.

Among the many problems troubling the world, some have to ponder whether to buy a Louis Vuitton Recto Verso card holder or a Louis Vuitton Pochette Cles (key pouch), two items similar in size and function.  LV describes the Pochette Cles as a “…playful yet practical accessory that can carry coins, cards, folded bills and other small items, in addition to keys. Secured with an LV-engraved zip, it can be hooked onto the D-ring inside most Louis Vuitton bags, or used as a bag or belt charm.”  The Recto Verso is said to be a “…versatile accessory offers multiple practical features, including a flap pocket, a zipped compartment with a wide, L-shaped opening, and four card slots. It also has a concealed hook and chain which allow it to be attached to a bag or belt.”

Amber Ashleigh’s guide to choosing between Louis Vuitton's Retro Verso and Pochette Cles (Key Pouch).

The retail price of the Retro Verso is between US$590-720 while the Pochette Cles lists between US$320-410 (the price varying with the material used in the construction) and while the solution obviously is to buy at least one of each, not all modern young spinsters can afford that so they should watch Amber Ashleigh’s invaluable guide.  Ms Ashleigh says this is among her “most requested videos.”

Macropterous & Brachypterous

Macropterous (pronounced muh-krop-ter-uhs)

(1) In zoology (mostly in ornithology, ichthyology & entomology), having long or large wings or fins.

(2) In engineering, architecture and design, a structure with large, untypical or obvious “wings” or “fins”.

Late 1700s: The construct was macro- +‎ -pterous.  Macro is a word-forming element meaning “long, abnormally large, on a large scale”, from the French, from the Medieval Latin, from the Ancient Greek μακρός (makrós), a combining form of makrós (long) (cognate with the Latin macer (lean; meager)), from the primitive Indo-European root mak (long, thin).  In English it is used as a general purpose prefix meaning “big; large version of”).  The English borrowing from French appears as early as the sixteenth century but it tended to be restricted to science until the early 1930s when there was an upsurge in the publication of material on economics during the Great Depression (ie as “macroeconomy” and its derivatives).  It subsequently became a combining form meaning large, long, great, excessive et al, used in the formation of compound words, contrasting with those prefixed with micro-.  In computing, it covers a wide vista but describes mostly relatively short sets of instructions used within programs, often as a time-saving device for the handling of repetitive tasks, one of the few senses in which macro (although originally a clipping in 1959 of “macroinstruction”) has become a stand-alone word rather than a contraction.  Other examples of use include macrophotography (photography of objects at or larger than actual size without the use of a magnifying lens (1863)), macrospore (in botany, "a spore of large size compared with others (1859)), macroeconomics (pertaining to the economy as a whole (1938), macrobiotic (a type of diet (1961)), macroscopic (visible to the naked eye (1841)), macropaedia (the part of an encyclopaedia Britannica where entries appear as full essays (1974)) and macrophage (in pathology "type of large white blood cell with the power to devour foreign debris in the body or other cells or organisms" (1890)).

The –pterous suffix was from the Ancient Greek, the construct being πτερ(όν) (pter(ón) (feather; wing), from the primitive Indo-European péthr̥ (feather) and related to πέτομαι (pétomai) (I fly) (and (ultimately), the English feather) +‎ -ous.  In zoology (and later, by extension, in engineering and design), it was appended to words from taxonomy to mean (1) having wings and (2) having large wings.  Later, it was used also of fins.  The –ous suffix was from the Middle English -ous, from the Old French –ous & -eux, from the Latin -ōsus (full, full of); a doublet of -ose in an unstressed position.  It was used to form adjectives from nouns to denote (1) possession of (2) presence of a quality in any degree, commonly in abundance or (3) relation or pertinence to.  In chemistry, it has a specific technical application, used in the nomenclature to name chemical compounds in which a specified chemical element has a lower oxidation number than in the equivalent compound whose name ends in the suffix -ic.  For example, sulphuric acid (H₂SO₄) has more oxygen atoms per molecule than sulphurous acid (H₂SO₃).  The comparative is more macropterous and the superlative most macropterous.  Macropterous & macropteran are adjectives and macropter & macroptery are nouns; the noun plural is macropters.

Google ngram: Because of the way Google harvests data for their ngrams, they’re not literally a tracking of the use of a word in society but can be usefully indicative of certain trends, (although one is never quite sure which trend(s)), especially over decades.  As a record of actual aggregate use, ngrams are not wholly reliable because: (1) the sub-set of texts Google uses is slanted towards the scientific & academic and (2) the technical limitations imposed by the use of OCR (optical character recognition) when handling older texts of sometime dubious legibility (a process AI should improve).  Where numbers bounce around, this may reflect either: (1) peaks and troughs in use for some reason or (2) some quirk in the data harvested.

Brachypterous (pronounced bruh-kip-ter-uhs)

In zoology (mostly in ornithology & entomology), having short, incompletely developed or otherwise abbreviated wings (defined historically as being structures which, when fully folded, do not reach to the base of the tail.long or large wings or fins.

Late 1700s: The construct was brachy- + -pterous.  The brachy- prefix was from the Ancient Greek βραχύς (brakhús) (short), from the Proto-Hellenic brəkús, from the primitive Indo-European mréǵus (short, brief).  The cognates included the Sanskrit मुहुर् (múhur) & मुहु (múhu), the Avestan m̨ərəzu.jīti (short-lived), the Latin brevis, the Old English miriġe (linked ultimately to the English “merry”) and the Albanian murriz.  It was appended to convey (1) short, brief and (2) short, small.  Brachypterous & brachypteran are adjectives and brachyptery & braˈchypterism are nouns.  The comparative would be more brachypterous and the superlative most brachypterous but because of the nature of the base word, that would seem unnatural.  The noun brachypter does not means “a brachypterous creature; it describes taeniopterygid stonefly of the genus Brachyptera”.

The European Chinch Bug which exists in both macropterous (left) and brachypterous (right) form; Of the latter, entomologists also use the term "micropterous" and use does seem interchangeable but within the profession there may be fine distinctions. 

The difference in the use of macropterous (long wings or fins) and brachypterous (short wings) is accounted for less by the etymological roots than the application and traditions of use.  In zoological science, macropterous was granted a broad remit and came to be used of any creature (form the fossil record as well as the living) with long wings (use most prevalent of insects) and water-dwellers with elongated fins.  The word was applied first to birds & insects before being used of fish (fins being metaphorical “wings” and in environmentally-specific function there is much overlap.  By extension, in the mid-twentieth century, macropterous came to be used in engineering, architecture and design including of cars, airframes and missiles.

Brachypterous (short wings) is used almost exclusively in zoology, particularly entomology, the phenomenon being much more common than among birds which, being heavier, rely for lift on wings with a large surface area.  Short wing birds do exist but many are flightless (the penguin a classic example where the wings are used in the water as fins (for both propulsion and direction)) and this descriptor prevails.  Brachypterous is less flexible in meaning because tightly it is tied to a specific biological phenomenon; essentially a “short fin” in a fish is understood as “a fin”.  Cultural and linguistic norms may also have been an influence in that while “macro-” is widely used a prefix denoting “large; big”, “brachy-” has never entered general used and remains a tool in biology.  So, in common scientific use, there’s no recognized term specifically for “short fins” equivalent to brachypterous (short wings) although, other than tradition, there seems no reason why brachypterous couldn’t be used thus in engineering & design.  If so minded, the ichthyologists could coin “brachyichthyous” (the construct being brachy- + ichthys (fish)) or brachypinnate (the construct being brachy- + pinna (“fin” or “feather” in Latin)), both meaning “short-finned fish”.  Neither seem likely to cath on however, the profession probably happy with “short-fin” or the nerdier “fin hypoplasia”.

The tailfin: the macropterous and the brachypterous

Lockheed P-38 Lightning in flight (left) and 1949 Cadillac (right).

Fins had appeared on cars during the inter-war years when genuinely they were added to assist in straight-line stability, a need identified as speeds rose.  The spread to the roads came from the beaches and salt flats where special vehicles were built to pursue the world land speed record (LSR) and by the mid 1920s, speeds in these contests were exceeding 150 mph (240 km/h) and at these velocities, straight-line stability could be a matter of life and death.  The LSR crew drew their inspiration from aviation and that field also provided the motif for Detroit’s early post-war fins, the 1949 Cadillac borrowing its tail features from the Lockheed P-38 Lightning (a US twin-boom fighter first flown in 1939 and built 1941-1945) although, despite the obvious resemblance, the conical additions to the front bumper bar were intended to evoke the image of speeding artillery shells rather than the P-38’s twin propeller bosses.

From there, the fins grew although it wasn’t until in 1956 when Chrysler released the next season’s rage that extravagance truly began.  To one extent or another, all Chrysler’s divisions (Plymouth, Dodge, DeSoto, Chrysler, Imperial) adopted the macropterous look and the public responded to what was being described in the press as “futuristic” or “jet-age” (Sputnik had yet to orbit the earth; “space-age” would soon come) with a spike in the corporation’s sales and profits.  The competition took note and it wasn’t long before General Motors (GM) responded (by 1957 some Cadillac fins were already there) although, curiously Ford in the US was always tentative about the fin and their interpretation was always rather brachypterous (unlike their English subsidiary which added surprisingly prominent fins to their Mark III Zephyr & Zodiac (1961-1966).

Even at the time the fins attracted criticism although it was just as part of a critique of the newer cars as becoming too big and heavy with a notable level of inefficiency (increasing fuel consumption and little (if any) increase in usable passenger space with most of the bulk consumed by the exterior dimensions, some created by apparently pointless styling features of which the big fins were but one.  The public continued to buy the big cars (one did get a lot of metal for the money) but there was also a boom in the sales of both imported cars (their smaller size among their many charms) but the corporation which later became AMC (American Motor Corporation) enjoyed good business for their generally smaller offerings.  Chrysler and GM ignored Ford’s lack of commitment to the macropterous and during the late 1950s their fin continued to grow upwards (and, in some cases, even outwards) but, noting the flood of imports, decided to join the trend, introducing smaller ranges; whereas in 1955, the majors offered a single basic design, by 1970 there would be locally manufactured “small cars”, sub-compacts”, “compacts” and “intermediates” as well as what the 1955 (which mostly had been sized somewhere between a “compact” and an “intermediate”) evolved into (now named “full-size”, a well-deserved appellation).

It was in 1959-1961 that things became “most macropterous” (peak fin) and the high-water mark of the excess to considered by most to be the 1959 Cadillac, east of the towering fins adorned with a pair of taillights often described as “bullet lights” but, interviewed year later, a member of the General Motors Technical Center (opened in 1956 and one of the mid-century’s great engines of planned obsolescence) claimed the image they had in mind was the glowing exhaust from a rocket in ascent, then often seen in popular culture including film, television and advertising.  However, although a stylistic high, it was the 1961 Imperials which set the mark literally, the tip of those fins standing almost a half inch (12 mm) taller and it was remembered too for the “neo-classical” touch of four free-standing headlights, something others in the industry declined to follow.

Tending to the brachypterous: As the seasons went by, the Cadillac's fins would retreat but would not for decades wholly vanish.

It’s a orthodoxy in the history of design that the fins grew to the point of absurdity and then vanished but that’s not what literally happened in all cases.  Some manufacturers indeed suddenly abandon the motif but Cadillac, perhaps conscious of having nurtured (and in a sense “perfected”) the debut of the 1949 range must have felt more attached because, after 1959, year after year, the fins would become smaller and smaller although decades later, vestigial fins were still obviously part of the language of design.  In Europe, others would also prune.

Macropterous to brachypterous.  Sunbeam Alpine: 1960 Series I (left) and 1966 Series V. 

Built in five series between 1959-1968, the fins on the Sunbeam Alpine would have seemed a good idea in 1957 when the lines were approved but trend didn’t persist and with the release in 1964 of the revised Series IV, the effect was toned down, the restyling achieved in an economical way by squaring off the rake at the rear, this lowering the height of the tips.  Because the release of the Series IV coincided with the debut of the Alpine Tiger (fitted initially with a 260 cubic inch (4.2 litre) V8 (and later a 4.7 (289)), all the V8 powered cars used the “low fin” body.

Regarded by some as a symbol of the way the Wirtschaftswunder (the post war “economic miracle” in the FRG (Federal Republic of Germany, the old West Germany)) had ushered away austerity, the (slight) exuberance of the fins which appeared on the Mercedes-Benz W111 (1959-1968) & W112 (1961–1965) seemed almost to embarrass the company, offended by the suggestion they would indulge in a mere “styling trend”.  Although the public soon dubbed the cars the Heckflosse (literally “tail-fins”), the factory insisted they were Peilstege (parking aids or sight-lines (literally "bearing bars")), the construct being peil-, from peilen (take a bearing; find the direction) + Steg (bar) which marked the extent of the bodywork, this to assist while reversing.  That may have been true (the company has never been above a bit of myth-making) but when a coupé and cabriolet was added to the W111 & W112 range, the fins were noticeably smaller, achieving an elegance of line Mercedes-Benz has never matched.  Interestingly, a la Cadillac, when the succeeding sedans (W108-W109 (1965-1972) & W116, (1972-1979)) were released, both retained a small hint of a fin although by 1972 it wasn’t enough even to be called vestigial; the factory said the small deviation from the flat was there to increase structural rigidity.

Macropterous to brachypterous: 1962 Vanden Plas Princess 3 Litre (left) and 1967 Vanden Plas Princess 4 Litre R (right).

The Italian design house Pinninfarina took to fins in the late 1950s and applied what really were variations of the same basic design to commissions from Fiat, Lancia, Peugeot and BMC (British Motor Corporation, a conglomerate created by merger in 1952 which brought together Morris, Austin (and soon Austin-Healey), MG, Riley, Wolseley & Vanden Plas under the one corporate umbrella.  There were a several BMC “Farinas” sold under six badges and the ones with the most prominent fins were the “big” Farinas, the most expensive of which were Princess 3 Litre (1959-1960), Vanden Plas Princess 3 Litre (1960-1964) and Vanden Plas Princess 4 Litre R (1964-1968); the “R” appended to the 4 Litre’s model name was to indicate its engine (which had begun life as a military unit) was supplied by Rolls-Royce, a most unusual arrangement.  The 4 Litre used the 3 Litre’s body with a number of changes, one of which was a change in the shape and reduction in the size of the rather chunky fins.  Although the frumpy shell remained, the restyling was thought quite accomplished though obviously influenced by the Mercedes-Benz W111 & W112 coupés & cabriolets but if one is going to imitate, one should choose to emulate the finest.

Naiad

Naiad (pronounced ney-ad, ney-uhd or nahy-ad)

(1) In Classical Mythology, a nymph (a female deity) dwelling in (in some stories “presiding over”) a lake, river, spring or fountain.

(2) In entomology, aquatic larva or juvenile form of the dragonfly, damselfly, mayfly and related insects.

(3) In botany, any monocotyledonous submerged aquatic plant of the genus Naias (or Najas), having narrow leaves and small flowers (of the family Naiadaceae (or Najadaceae) and also called the water nymph.

(4) In malacology, any of certain freshwater mussels of the genus Unio.

(5) In informal use, a female swimmer, especially a young, expert one.

Circa 1600: From the Latin Nais, Naias & Nāïad- (stem of Nāïas, genitive naiadis), from the Ancient Greek Nāïás (plural Naiades) (a water nymph) and related to νάω (náō or náein) (to flow), from the primitive Indo-European naw-yo-, a suffixed form of snau & nau- (to swim, flow, let flow (from the primitive Indo-European root sna- (to swim).  The English poet, literary critic, translator and playwright John Dryden (1631–1700) used the Latin singular form Nais; In English, the plural form Naiades was in use as early as the late fourteenth century and the use of the initial capital was inconsistent, something not unusual in Middle and early Modern English .  Naiad is a noun; the noun plural is naiads or naiades.

The companion term (in the sense they were often riparian (growing on the bank of a river or stream)) was dryad (a female tree spirit), from the Old French driade (wood nymph), from the Latin Dryas & Dryadis, from the Ancient Greek Δρυάς (Druás) (dryad), from δρῦς (drûs) (oak), from the primitive Indo-European derew & derewo- (tree, wood) and related to the primitive Indo-European dóru (tree).  The niads should not be confused with the Nereids (plural Nereids or Nereides).  In Greek Mythology, Nerids were one of 50 sea nymphs who were attendants upon Poseidon (Neptune); they were represented riding on sea horses, sometimes in human form and sometimes with the tail of a fish.  In zoology, nerid is an alternative form of nereidid (any polychaete worm of the Nereididae).  Nereid was from the stem of the Latin Nērēis (sea-nymph), from the Ancient Greek Νηρηΐς (Nērēḯs), from Νηρεύς (Nēreús) (the sea-god Nereus).

The Naiads were water nymphs who, although very long-lived, were mortal, a physiology not unique among the deities of Classical Mythology and although the Naiads incarnate the divinity of the spring or stream which they inhabited, a waterway could be the home to more than one of the nymphs; presence did not confer an exclusivity of dominion.  As is typical of the myths, the stories often are inconsistent for although Homer said the Naiads were the daughters of Zeus, elsewhere they’re described as daughters of the waters in which they dwell.  The daughters of Ασωπός (Asopus) were Naiads.  Asopus (Ασωπός) was the god of the river Asopus and (the family tree is typically murky and varies with the source) was either son of Poseidon & Pero, of Zeus & Eurynome or of Oceanus & Tethys.  He married Metope, the daughter of Ladon, fathered two sons (Ismenus and Pelagon) and an impressive 20 daughters although The Greek historian of the first century BC, Διόδωρος (Diodorus of Sicily) listed the names only of a dozen (Corcyra, Salamis, Aegina, Pirene, Cleone, Thebe, Tanagra, Thespia, Asopis, Sinope, Oenia (or Ornia) and Chalcis.  Confusingly Asopus is in other places mentioned as the said to be the father of Antiope and Plataea (that genealogy contested by other authors), after whom the city Plataea is named.  Plataea was a city-state in Boeotia at the foot of Mount Cithaeron, between the mountain and the river Asopus (which divided its territory from that of Thebes).  The modern Greek town of Plataies is adjacent to its ruins.

Led astray by freshwater sirens: Hylas and the Nymphs (1896), oil on canvas by the aptly named John William Waterhouse (1849–1917), Manchester Art Gallery, England.  Ύλας (Hylas) would not long live to enjoy his flirtation with a pack of Naiads.  Much taken by his beauty, the naiads lured the youth to the water for their pleasure, after which, according to the Roman Poet Ovid (Publius Ovidius Naso; 43 BC–17 AD), they drowned him; at the least, that suggests ingratitude.  Hylas may have died content but that's not something on which Ovid dwelt.

In theory, there shouldn't be a river or spring without at least one naiad but the storied ones were those associated with famous waterways and many of the nymphs had adventures (not always welcome) with the good, great and ghastly.  At Syracuse dwelt the beautiful Αρέθουσα (Arethusa; all nymphs were beauties but Arethusa was a supermodel among the breed), a companion of Αρτεμις (Artemis) who was identified by the Romans with Diana.  Some said she was the daughter of Demeter, but in most stories she was the twin sister of Apollo, their parents being Zeus and Leto.  One day, while swimming in the river (something which, unsurprisingly, the Naiads often did), Arethusa realized she wasn’t alone when she heard the voice of Alpheus, the god of the river, whose crush on her had developed into a passion which included stalking her.  Pursued by the lustful god, the nymph fled, crying out for Artemis to save her from what she knew would be an awful fate.  Artemis surrounded her in a concealing fog but Alpheus refused to leave the place where the mist swirled and in fright, Arethusa turned into a fountain.  In the way the myths handle the physics of such circumstances, the earth opened up to prevent Alpheus mingling his own waters with those of the spring which Arethusa had become, and, guided by Artemis, Arethusa went through underground channels to Syracuse, on the Island of Ortygia (which is dedicated to Artemis).  This Hellenistic myth is preferred by most but another version of the attempted sexual assault involves Αλφειός (Alpheus, (another river god)) which differs only in detail.

The Naiads were often claimed to possess powers of healing and the notion of “curing waters” persists into the twenty-first century; although some of this is quackery there is a scientific basis in some cases and the origin of the use of lithium as an early anti-depressant was physicians in Ancient Greek noting the drinking of waters from a certain place “cured men of melancholy”.  Those waters turned out to have a pharmacologically significant lithium content.  However, not all naiads could be used so efficaciously because bathing in certain springs or rivers could be considered sacrilegious, even if it was someone exulted taking a dip.  Nero (Nero Claudius Caesar Augustus Germanicus (37-68; Roman emperor (and the final emperor of the Julio-Claudian dynasty) 54-68)) was attacked by fever and some sort of partial paralysis and after bathing in the source of the Aqua Marcia and the Roman scuttlebutt was he’s incurred the displeasure of the Naiads, something which brought Nero’s subjects some delight.  Clearly, one upset a Naiad a one’s own risk because it was said also they could visit madness upon those who laid eyes on them, the nymphs possessing the mortal spirit of a transgressor and driving them to insanity.  For this reasons, travelers were warned (the Trip Advisor concept is not new) Naiads were particularly numerous in the Péloponnèse, a place of many waterways.
