Callosity

Callosity (pronounced kuh-los-i-tee)

(1) In pathology, an alternative name for a callus.

(2) In botany, a hardened or thickened part of a plant.

(3) In zoology, as ischial callosity, a large callus on the butts of certain animals.

(4) In the human condition, being of a callous demeanor; insensitivity or hard-heartedness

1375–1425: From the late Middle English calosite, from the Late Latin callōsitās, the construct being callōs(us) (callous) (from callum (hardened skin) +‎ -ōsus (the suffix added to a noun to form an adjective indicating an abundance of that noun)) + -itās which in English was rendered as callus + -ity, the substitute “o” a familiar device.  The –ity suffix was from the French -ité, from the Middle French -ité, from the Old French –ete & -eteit (-ity), from the Latin -itātem, from -itās, from the primitive Indo-European suffix –it.  It was cognate with the Gothic –iþa (-th), the Old High German -ida (-th) and the Old English -þo, -þu & -þ (-th).  It was used to form nouns from adjectives (especially abstract nouns), thus most often associated with nouns referring to the state, property, or quality of conforming to the adjective's description.  Callosity is a noun; the noun plural is callosities.

Essentially a thickening of the skin which forms in response to damage, a callus is one of the body’s protective mechanisms and example of how human skin have evolved to respond to a “fragile” area by replacing it with something “anti-fragile”.  The skin is a good barrier to much which would be dangerous if able to penetrate the surface but easily it can be cut and it’s prone to delimitation if exposed to repeated friction, something well known to gardeners digging holes, the skin on the palms of the hands soon “wearing off” at the points where the handle of the shovel repeatedly rubs.  That will be painful but the body will respond, replacing the dead skin with new skin which is thicker and harder, thus enabling the gardener to soon again pick up their shovel and return to their excavations.  This is an example of the general principle of healthy human physiology which responds to damage not by replacing things with something just as strong but something stronger, able to resist whatever force it was which caused the injury and it is the same with a bone fracture; when the bone knits back together, it will not be merely as strong as it was but a little stronger.  The new skin on the gardener’s hands will also be stronger and as the holes continue to be dug, the skin will become more robust still but the difference should not be thought of as fragile vs robust but as fragile vs anti-fragile, the point being that as pressure is applied, the material responds by becoming less-fragile.

Fragile and robust, although often used as antonyms (and in general use usefully so because the meanings are so well conveyed and understood) are really not opposites but simply degrees of the same thing.  In the narrow technical sense an expression of robustness or fragility is a measure of the same thing; a degree of strength.  The traditions of language obscure this but it becomes clear if measures of fragility or robustness are reduced to mathematics and expressed as comparative values in numbers.  It's true that on such a continuum a point could be set at which point something is regarded as no longer robust and becomes defined as fragile (indeed this is the essence of stress-testing) but this doesn't mean one is the antonym of the other.  The opposite of fragile is actually anti-fragile (the anti prefix was from the Ancient Greek ἀντι- (anti-) (against, hostile to, contrasting with the norm, opposite of, reverse (also "like, reminiscent of"))).  The concept is well known in physiology and part of the object in some forms of strength training is to exploit the propensity of muscles to tear at stress points, relying on the body to repair these tears in a way that doesn’t restore them to their original form but makes them stronger so that if subjected again to the same stress, a tear won’t happen.  It’s thus an act of anti-fragility, the process illustrated also by the calluses which form on the hands after the skin blisters in response to work.  Fragile and robust merely express points on a spectrum and are used according to emphasize the extent of strength; anti-fragile is the true opposite.

The idea of anti-fragile was introduced by Lebanese-born, US-based mathematician and trader Nassim Nicholas Taleb (b 1960) in the book Antifragile: Things That Gain From Disorder (2012), the fourth of five works which explore his ideas relation to uncertainty, randomness & probability, the best-known and most influential was The Black Swan: The Impact of the Highly Improbable (2007).  His work was thoughtful, intriguing and practical and was well received although the more accessible writing he adopted for the later volumes attracted criticism from some who felt an academic style more suited to the complex nature of his material; probably few who read the texts agreed with that.  Apart from the ideas and the use to which they can be put, his deconstruction of many suppositions was also an exploration of the rigidities of thought we allow our use of language to create.

Anti-callus devices (gloves the most common type) are used when the aim is to avoid the growth of a callus, the use of an “artificial callus” sometimes preferable to the natural.  A carpet layer in knee pads (left) and bra strap “cushions” (right).

When the new areas of skin are called calluses (calli the alternative plural), callus from the Latin callum (hard skin).  Most often used to describe the hardened areas of skin (typically on hands & feet) induced as a response to repeated friction, wear or use, in anatomy, the same word is applied to the initially soft or cartilaginous substance exuded at the site of a bone fracture which converts ultimately into bone, knitting the fragments into the one piece.  One the process fully is complete, if again exposed to the same stress, the bone will not break.  In botany, it’s used of the new formation over the end of a cutting. Callus is a noun & verb, the calluses, the present participle callusing and the past, callused.

In some professions, the callus can be close to essential; those whose life involves supporting weights on their shoulders form them on the pressure points, enabling them to ply their trade without undue pain or further damage.  However, not all whose shoulders might suffer welcome calluses, however beneficial they might be:  Women who wish to avoid what manufactures term the “shoulder grooving” caused by the pressure of their bra’s shoulder straps (the physics of this a product of (1) the weight supported and (2) its surface distribution which is dictated essentially by the width of the strap) can buy inserts for the straps which increase the surface area, thereby reducing the specific loading by re-distributing the downward pressure.  A variation on this idea is the “knee pad” worn by those who lay carpets, floor tiles and such.  These folk are compelled to work “on their knees” for hours at a time, often upon hard and sometimes rough surfaces and although, given time, calluses would form were the work to be performed unprotected, it would not be a pleasant experience and the degree of hardening needed would likely adversely affect normal mobility.  In zoology, calluses are a noted environmental adaptation among some species, (Old World) gibbons, monkeys and some chimpanzees having evolved notably large calluses on their butts (described as ischial callosities (the seventeenth century ischium (from the Latin ischium, from the Ancient Greek ἰσχίον (iskhíon) (hip joint)) describing the lowest of the three bones that make up each side of the pelvis).  On the animals so endowed, the advantage is the ability to sleep while sitting upright on thin branches, safe from both predators and the risk of falling.

In figurative use callosity came to be used to refer to one with a lack of feeling or capacity for emotion but the use when documented comes usually with the caveat that those so described are not “psychopaths” but merely the “hard-hearted”.  So it’s there to be used and if it seems not to suit, English offers has quite an array of choice when speaking of those lacking emotional range.  There is “heartless” & “hard-hearted”, both of which allude to the ancient idea of the special significance of the heart as the source of all that human feeling and character; even now it’s known to be a “just a pump”, the romantic notions persist in many culture and variations of the ❤ symbol are among the most frequently used emojis.  “Cold-blooded” is different in that although it’s blood the heart pumps, the operative word really is “cold”, implying decisions made or actions taken without emotion intruding and in idiomatic use, a “cold-blooded murder” (such as a contract killing done for payment) is viewed with less sympathy than a crime of passion (such murderers of said to have been “seeing the red mist” of “hot” blood at the time of their crime.  “Stolid” and “impassive” differs in that they can often be virtues and anyway suggest not an absence of capacity for feeling but its repression and one who wrote on how essential that was to civilization yet simultaneous damaging to individuals was Sigmund Freud (1856-1939), his ideas later taken up by German-American philosopher Herbert Marcuse (1898–1979).  Mankind probably didn’t surprise Freud but doubtless we disappointed Marcuse.  Finally, there is “stoic” which traces back to the Hellenic school of stoicism, a philosophy with a great following in Antiquity which was intended always to be practical, a way to help citizens live good lives rather than anything concerned with abstractions.  In its pure form it survives in that form but the modern re-purposing of the word means it’s now used to mean something like “suffering in silence”.  “Callosity” then is one of many ways to refer to the “unfeeling” and its use in this context is based on the use in medicine, a callosity (ie a callus) being “skin of abnormal hardness & thickness” which can be poked or pricked with the subject barely feeling the intrusion.  In that it’s subtly different from “thick skinned” which usually means “not easily offended”.

Fragile

Fragile (pronounced fraj-uhl (U) or fraj-ahyl (non-U))

(1) Easily broken, shattered, or damaged; delicate; brittle; frail.

(2) Vulnerably delicate, as in appearance.

(3) Lacking in substance or force; flimsy.

1505–1515: From the Middle English fragile (liable to sin, morally weak), from the Middle French fragile, from the fourteenth century Old French fragele, from the Latin fragilis (easily broken) (doublet of frêle), the construct being frag- (variant stem of the verb frangere (break), from the primitive Indo-European root bhreg- (to break) + -ilis.  The -ilis (neuter -ile) suffix was from the Proto-Italic -elis, from the primitive Indo-European -elis, from -lós; it was used to form an adjective noun of relation, frequently passive, to the verb or root.  It was cognate with fraction & fracture and doublet of frail.  The original meaning from circa 1510 (liable to sin, morally weak) by circa 1600 extended to "liable to break" as a back-formation from fragility which was actually an adoption of the sense in Latin.  The transferred sense "of frail constitution" (of persons) dates from 1858.  The companion adjective frail emerged in the mid fourteenth century in the sense of "morally weak", from the twelfth century Old French fraile & frele (weak, frail, sickly, infirm) (enduring in Modern French as frêle), from the Latin fragilis.  The US slang noun meaning "a woman" is documented from 1908 and although there’s no evidence, etymologists have noted Shakespeare's "Frailty, thy name is woman" (Hamlet, Act I, Scene 2).  The comparative fragiler and the superlative fragilest are both correct but the more elegant “more fragile” and “most fragile” tend to be preferred.  Fragile is used usually as an adjective but can be applied as a noun (typically by folk like furniture movers) or in the same way as “exquisite”.  Fragilely is an adverb and fragility is a noun; the noun plural is fragiles.

Words which are either synonyms or close in meaning include delicate, feeble, frail, weak, brittle, crisp, crumbly, decrepit, fine, flimsy, fracturable, frangible, friable, infirm, insubstantial, shivery, slight & unsound.  The antonym most often used to suggest the opposite quality to fragile is “robust” (evincing strength and health; strong).  Robust dates from circa 1545 and was a learned borrowing from circa 1400 Medieval Latin rōbustus (oaken, hard, strong), the construct being rōbus- (stem of rōbur (oak, strength) + -tus (the adjectival suffix).

However, fragile and robust, although often used as antonyms (and in general use usefully so because the meanings are so well conveyed and understood) are really not opposites but simply degrees of the same thing.  In the narrow technical sense an expression of robustness or fragility is a measure of the same thing; a degree of strength.  The traditions of language obscure this but it becomes clear if measures of fragility or robustness are reduced to mathematics and expressed as comparative values in numbers.  It's true that on such a continuum a point could be set at which point something is regarded as no longer robust and becomes defined as fragile (indeed this is the essence of stress-testing) but this doesn't mean one is the antonym of the other.

The opposite of fragile is actually antifragile (the anti prefix was from the Ancient Greek ἀντι- (anti-) (against, hostile to, contrasting with the norm, opposite of, reverse (also "like, reminiscent of"))).  The concept is well known in physiology and part of the object in some forms of strength training is to exploit the propensity of muscles to tear at stress points, relying on the body to repair these tears in a way that doesn’t restore them to their original form but makes them stronger so that if subjected again to the same stress, a tear won’t happen.  It’s thus an act of antifragility, the process illustrated also by the calluses which form on the hands after the skin blisters in response to work.  Fragile and robust merely express points on a spectrum and are used according to emphasize the extent of strength; antifragile is the true opposite.

The idea of antifragile was introduced by Lebanese-born, US-based mathematician and trader Nassim Nicholas Taleb (b 1960) in the book Antifragile: Things That Gain From Disorder (2012), the fourth of five works which explore his ideas relation to uncertainty, randomness & probability, the best-known and most influential was The Black Swan: The Impact of the Highly Improbable (2007).  His work was thoughtful, intriguing and practical and was well received although the more accessible writing he adopted for the later volumes attracted criticism from some who felt an academic style more suited to the complex nature of his material; probably few who read the texts agreed with that.  Apart from the ideas and the use to which they can be put, his deconstruction of many suppositions is also an exploration of the rigidities of thought we allow our use of language to create.

Bohemian

Bohemian (pronounced boh-hee-mee-uhn)

(1) A native or inhabitant of Bohemia.

(2) A person, as an artist or writer, who lives and acts free of regard for conventional rules and practices (technically should be lowercase but rule often not observed.)

(3) The Czech language, especially as spoken in Bohemia.

(4) Slang term sometime applied to Gypsies (Roma or Travelers), especially in central and eastern Europe.

(5) Of or relating to Bohemia, its people, or their language, especially the old kingdom of Bohemia; a Czech.

(6) Pertaining to or characteristic of the unconventional life of a bohemian (again, should be lowercase).

(7) Living a wandering or vagabond life.

1570-1580:  The construct was Bohemi(a) + -an (the adjectival suffix).  The modern meaning "a gypsy of society" dates from 1848, drawn from the fifteenth century French bohemién, from the country name.  Meaning is thus associative, from the prevailing French view that gypsies (Roma or Travelers) came from Bohemia (and technically, their first appearance in Western Europe may have been directly from Bohemia).  An alternative view is it’s from association with fifteenth century Bohemian Hussite heretics who had been driven from their country about that time; most etymologists prefer the former.

A bohemian was thus something of “a gypsy of society; a person (especially a painter, poet etc) who lives a free and somewhat dissipated life, rejecting the conventionalities of life and having little regard for social standards”.  The transferred sense, in reference to unconventional living, is attested in French by 1834 and was popularized by Henri Murger's (1822-1861) stories from the late 1840s, later collected as Scenes de la Vie de Boheme (which formed the basis of Puccini's La Bohème).  It appears in English in that sense in William Makepeace Thackeray's (1811–1863) Vanity Fair (1848); the Middle English word for "a resident or native of Bohemia" was Bemener.

1934 German 40 Pf postage stamp.  President von Hindenburg once vowed never to appoint Hitler Chancellor (head of government), saying the highest office he's grant would be as a postmaster where "he could lick the stamps with my head on them."

As a descriptor of lifestyle, in the West, bohemian sometimes has a romantic association with freedom but it can also be a put-down.  In translation it can also be misunderstood.  Paul von Hindenburg (1847–1934; Field Marshal and German head of state 1925-1934) dismissively called Adolf Hitler (1889-1945; Nazi head of government 1933-1945 & head of state 1934-1945) a Böhmischer Gefreiter which is usually translated in English as “bohemian corporal”, leading many to conclude it was a reference to his famously erratic routine and self-described (and promoted) artistic temperament.  Actually Hindenburg was speaking literally.  In the Austro-Prussian War of 1866, he’d served as an officer in the Prussian Army, at one point passing through the Bohemian village named Broumov (Braunau in German and now located in the Czech Republic) and knowing Hitler had been born in Braunau, assumed the future Führer had been born a Bohemian.  Hitler however was actually born in the Austrian town of Braunau in Austria although the Field Marshal was right about him being a Gefreiter (an enlisted rank in the military equating with a lance corporal or private first class (PFC)), that being Hitler’s role in the First World War (1914-1918)).  If vague on geography, one would expect Hindenburg to get the military terminology correct; he once claimed the only books he ever read were the Bible and the army manual.

Either way, the president’s slight was a deliberate, class-based put-down, the army’s often aristocratic (and predominately Prussian) officer corps regarding a corporal from somewhere south as definitely not “one of us” and one didn’t even have to come from as far south as Austria to earn Prussian disapprobation; Otto von Bismarck (1815–1898; Chancellor of the German Empire 1871-1890) once described Bavarians as “halfway between an Austrian and a human being”.  Even a Bavarian officer however could think himself superior to an Austrian corporal and Ernst Röhm (1887-1934; the most famous victim of the 1937 Nacht der langen Messer (Night of the Long Knives (Unternehmen Kolbri (Operation Hummingbird)) and referred to by the Nazis as the Röhm Putsch) more than once dismissed Hitler as a lächerlicher Gefreiter (ridiculous corporal).  Hindenburg’s phrase was well-known among the officer corps and generals were known to repeat it when among friends.  Most famously it was reprised by Field Marshal Friedrich Paulus (1890–1957) who is now remembered only for commanding the doomed Sixth Army, surrendering the remnants to Soviet forces in February 1943.  Hitler promoted him to Field Marshal just before the city fell, explaining that he wanted to give him “this last satisfaction”, the sub-text being that no German Field Marshal had ever been captured and that Paulus should draw his own conclusions and commit suicide.  Paulus however decline to shoot himself for that “Böhmischer Gefreiter”.

La Bohème (1896) by Giacomo Puccini

In 1830s Paris, some bohemian youths are living in squalid flats in the Latin Quarter.  Two of them, the writer Rodolfo and the frail Mimi, meet by chance when Mimi knocks on her neighbor Rodolfo’s door because her solitary candle has blown out.  He lights it for her and they fall in love.  These days, they'd be thought a couple of emos.

They have their ups and downs, as Puccini’s lovers do, and Rodolfo, though finding Mimi a bit highly-strung, really loves her but fears her staying with him and living in such poverty will damage her fragile health.  Worried she may die, he decides to leave.  Hearing this, Mimi is overcome with feelings of love and they make a pact to stay together until spring, after which they can separate.

In early spring, in Rodolfo arms, Mimi falls gravely ill and the bohemians rush off to sell their meager possessions so they can buy her medicine.  Together the two lovers recall how they met and talk of their poor, happy days together.  She takes medicine but her condition worsens and she dies, leaving Rodolfo in inconsolable grief.

Maria Callas (1923-1977) was as improbable a Mimi as she was a Madam Butterfly and never performed the role on-stage.  However, in 1956, under Antonino Votto (1896-1985) in Milan, she, with Giuseppe di Stefano (1921-2008) as Rodolfo, recorded the Opera for Decca and it’s one of the great Callas performances.  To this day, it's the most dramatic La Bohème available on disc.

A generation later, under Herbert von Karajan (1908-1989), Mirella Freni (1935-2020) and Luciano Pavarotti (1935-2007) recorded it for Decca.  Karajan, better known for conducting Wagner with hushed intensity, produced a lush and romantic interpretation.

In fashion, the bohemian look (boho or boho chic for short) is sometimes said to be not precisely defined but that’s really not true because the style is well-understood and, done properly, can’t be mistaken for anything else.  Although the trick to the look is in the layering of the elements, the style is characterized by long flowing or tiered skirts and dresses, peasant blouses, clichéd touches like tunics or wood jewelry, embroidery or embellishment with beading, fringed handbags, and jeweled or embellished flat sandals (or flat ankle boots).  Boho dresses owe much to the pre-Raphaelite women of the late nineteenth century although in the popular imagination there’s more of an association with the hippies of the 1960s (and those of the 1970s who didn’t realize the moment had passed).  The terms bohemian & boho obviously long pre-dated the hippie era but as fashion terms boho & boho-chic didn’t come into widespread use until early in the twenty-first century.

Spat

Spat (pronounced spat)

(1) A petty quarrel; a dispute.

(2) A light blow; a slap or smack (now rare).

(3) A classic footwear accessory for outdoor wear (technically an ankle-length gaiter), covering the instep and ankle, designed to protect these areas from mud & stones etc which might be splattered (almost always in the plural).

(4) In automotive design, a piece of bodywork on a car's fender encapsulating the aperture of the wheel-arch, covering the upper portion of the wheel & tyre (almost always on the rear) and used variously to reduce drag or as a aesthetic choice.

(5) In aviation, on aircraft with fixed under-carriages, a partial enclosure covering the upper portion of the wheel & tyre, designed to reduce drag.

(6) In zoology, a larval oyster or similar bivalve mollusc, applied particularly when one settles to the sea bottom and starts to develop a shell; young oysters collectively, especially seed oysters.

1350-1400: From the Middle English spat (argument, minor scuffle), from the Anglo-Norman spat, of unknown origin but presumed related either to (1) being the simple past tense & past participle of spit or (2) something vaguely imitative of the sound of a dispute in progress.  In use, a spat implies a dispute which is minor and brief.  That doesn’t preclude violence being involved but the word does tend to be applied to matters with few serious consequences but a spat can of course escalate to something severe at which point it ceases to be a spat and becomes a brawl, a fight, a murder, a massacre or whatever the circumstances suggest is appropriate.  Otherwise, a spat is synonymous with words like bickering, brouhaha, disagreement, discord, falling-out, feud, squabble, tiff or argument.

As a descriptor of the short gaiter covering the ankle (which except in technical and commercial use is used only in the plural), use dates from 1779 as an invention of American English and a shortening of the trade-terms spatterdash (or splatterguard) (long gaiter to keep trousers or stockings from being spattered with mud), the construct being spatter + dash (or guard), the former the same idea as the noun dashboard which was a timber construction attached to the front of horse-drawn carriages to protect the passengers from mud or stones thrown up when the beasts were at a dash.  In cars, the use of the term dashboard persisted although the device both shifted rearward (aligned with the cowl (scuttle) & windscreen) and changed in function.  In aircraft where the link to horse-drawn transport didn’t exist, the preferred equivalent term became “instrument panel”.

Spats date from a time when walking in cities could be a messy business, paved surfaces far from universal.  As asphalt and concrete became commonplace in the twentieth century, spats fell from frequent use though there were those who clung to them as a fashion accessory.  Stanley Melbourne Bruce (1883–1967; prime minister of Australia 1923-1929) liked spats and wore them as late as the 1940s but historians of fashion note it's said nothing was more influential in their demise than George V (1865–1936; King of the United Kingdom 1910-1936) eschewing them after 1926.  They days, they're seen only in places like the Royal Enclosure at Ascot or smart weddings although variations are still part of some ceremonial full-dress military uniforms.  Technically, a spat probably can be called a “short” or “ankle-length” gaiter but it’s wise to use “spat” because gaiters are understood as extending higher towards the knee.

On the Jaguar 2.4 & 3.4 (1955-1959, top row; later retrospectively named Mark 1), full-sized spats were standard equipment when the standard wheels were fitted but some owners used the cut-down versions (available in at least two designs) fitted when the optional wire wheels were chosen.  For use in competition, almost all drivers removed the spats.  The Mark 2 (bottom row;1959-1969) was never fitted with the full-size units but many used slimmer version available from both the factory and third-party suppliers; again, in competition, spats in any shape were usually discarded.  On the big Jaguars, spats (which had already been scalloped) disappeared after production of the Mark IX ended in 1961.    

On cars, it wasn’t until the 1930s that spats (which some English manufacturers called "aprons" and in the US they came to be called “fender-skirts” though the original slang was “pants”) began to appear as the interest in streamlining and aerodynamic efficiency grew and it was in this era they became also a styling fad which, for better and worse, would last half a century.  They’d first been seen in the 1920s as aerodynamic enhancements on speed record vehicles and some avant-garde designers experimented with enveloping bodywork but it was only late in the decade that the original style of separate mudguards (later called cycle-fenders) gave way to more integrated coachwork where the wheel-arch was an identifiable feature in the modern sense.  Another issue was that the early tyres were prone to wear and damage and needed frequently to be changed, hence the advantage of making access to the wheels un-restricted.  In the 1930s, as streamlining evolved as both a means to reduce drag (thus increasing performance and reducing fuel consumption) and as a styling device, the latter doubtlessly influenced by the former.  On road cars, spats tended to be used only at the rear because of the need to provide sufficient clearance for the front wheels to turn although there were manufacturers (Delahaye, Nash and others) which extended use to the front and while this necessitated compromise (notably the turning circle and cooling of the brakes), there were some memorable art-deco creations.

The aerodynamic advantages were certainly real, attested by the tests conducted during the 1930s by Mercedes-Benz and Auto-Union, both factories using spats front and rear on their land-speed record vehicles, extending the use to road cars although later Mercedes-Benz would admit the 10% improvement claimed for the 1937 540K Autobahn-kurier (highway cruiser) was just “a calculation” and it’s suspected even this was more guesswork than math.  Later, Jaguar’s evaluation of the ideal configuration to use when testing the 1949 XK120 on Belgium roads revealed the rear spats added about 3-4 mph to top speed though they precluded the use of the lighter wire wheels and did increase the tendency of the brakes to overheat in severe use so, like many things in engineering, it was a trade-off.

1958, 1959 & 1960 Chevrolet Impalas.  Not actually wildly popular when new, accessory spats now often appear on restored cars as a “period accessory”.

In the post-war years, concerns with style rather than specific aerodynamic outcomes probably prevailed.  In the US especially, the design motifs borrowed from aircraft and missiles (where aerodynamic efficiency was important and verified in wind tunnels) were liberally applied to automobiles but in some cases, although they actually increased drag, they anyway appeared on production cars because they lent the desired look.  Because they added to the cost of production, spats tended often to be used on the more expensive ranges, this association encouraging after-market accessory makers to produce them, often for models where they’d never been available as a factory fitting or option.  Although now usually regarded as naff (at least), there’s still some demand because they are fitted sometimes (often in conjunction with that other acquired taste period-accessory, the "Continental" spare-tyre kit) by those restoring cars from the era although the photographic record does suggest that when the vehicles were new, such things were vanishingly rare.

Spats vanished from cars made in the UK and Europe except among manufacturers (such as Citroën) which made a fetish of conspicuous aerodynamics and in the US, where they endured, increasingly they appeared in cut-down form, exposing most of the wheel with only the upper part of the tyre concealed.  By the mid 1990s spats appeared only on some of the larger US cars (those by then also down-sized from their mid-seventies peak) and none survived into the new century, the swansong the 1996 Cadillac DeVille.  However, the new age of efficiency did see a resurgence of interest with spats (some actually integrated into the bodywork rather than being detachable) used on some electric and hybrid vehicles where every possible way of optimizing the use of energy is deployed.

Pioneered by Mercedes-Benz and Auto-Union during the 1930s when the factory racing programmes were being subsidized by the Nazi regime as a national prestige project, spats were used on the specially tuned cars used for land-speed record attempts though not on the circuits where the air-flow was needed for brake cooling.  The use on the road cars was sometimes an overt allusion to the quest for aerodynamic efficiency such as those added to the streamlined 540K Autobahn-kurier (highway cruiser) but their use on big machines like the 770K was simply as a styling tool.  The highest evolution of the 1930’s theme was the aero-engined T-80, intended to lay siege to the world Land-Speed Record (LSR).  Powered by a 3,500 hp (2,600 kW), 44.5 litre (2,716 cubic inch) Daimler-Benz DB 603 inverted V12 (most of which were supplied to the Luftwaffe), calculations (all then by slide-rule) suggested it should reach 750 km/h (466 mph) on a 10 kilometre (6 mile) stretch of the Autobahn, closed to other traffic for the occasion.  Scheduled for January 1940, the outbreak of war meant the T-80 never ran.  In the years since, partial or complete spats have often been used on high-speed vehicles in competition.

The most extraordinary vindication of the concept was probably the 1970 Chaparral 2J, built for the Canadian-American Challenge Cup (the Can-Am, a series for unlimited displacement sports cars under the FIA’s minimalist Group 7 rules).  Although using a similar frame and power-plant (the all aluminum, 427 cubic inch (7.0 litre) Chevrolet V8 (ZL1)) as most of its competition, it differed in that the bodywork was rather more rectilinear, the transmission was semi-automatic and, most intriguingly, the use of two small auxiliary engines (Rockwell JLO 247 cm³ two-stroke, two-cylinder units which usually powered snowmobiles).  Unlike the auxiliary engines used in modern hybrids which provide additional or alternative power, what the Rockwells did was drive two fans (borrowed from the M-109 Howitzer, the US Army’s self-propelled 155 mm (6 inch) cannon) which pumped air from underneath at 9650 cfm (cubic feet per minute) (273 m3 per minute), literally sucking the 2J to the road, the technique enhanced by a Lexan (a thermoplastic polymer) skirt which partially sealed the gap between the shell and the road.  The rear spats (integrated into the body-shell) were part of the system, offering not only their usual contribution to reduced drag but increasing the extent of the suction generated by the extractor fans.  The 2J was immediately faster than the competition but the suction system proved fragile although, as a proof of concept it worked and it was clear that only development was needed to debug things.  Unfortunately, innovation and high speeds have always appalled the FIA (the Fédération Internationale de l'Automobile which has for decades been international sport’s dopiest regulatory body) and they banned the 2J.  Really, the FIA should give up on motorsport and offer their services to competitive crochet where they can focus on things like pins and needles not being too sharp.

Fashions change and spats in the post-war years became unfashionable except in the odd market segment which appealed to an older demographic and even there, as the years were by, they were cut-away, revealing more of the wheel & tyre but they never entirely went away and designers with big computers now don’t even need even bigger wind tunnels to optimize airflow and spats have been displayed which are mounted vertically, some even responding to dynamic need by shifting location or direction.

Flown first in 1938 and named after the Spartan admiral Lysander (circa 467-395 BC), the Westland Lysander was a British army co-operation and communications aircraft used extensively during the Second World War (1939-1945).  Although it couldn’t match the extraordinary STOL (short Take-Off & Landing) performance of the its German contemporary the Fieseler Fi 156 Storch, it was capable, robust and had a good enough short-field capability to perform valuable service throughout the conflict.  Like many aircraft with a fixed undercarriage, partially enveloping spats were fitted to reduce drag but those on the Lysander had the unusual feature of being fitted with their own removable spats (similar to those used on automobiles).  Once these were dismounted, assemblies could be fitted to mount either Browning machine guns or stub wings which could carry light bombs or supply canisters.  The arrangement was popular with ground crew because the accessibility made servicing easy and pilots appreciated the low placement because the change in weight distribution had little adverse effect on handling characteristics.

Blueprint

Blueprint (pronounced bloo-print)

(1) A process of photographic printing, used chiefly in copying architectural and mechanical drawings, which produces a white line on a blue background; also called a cyanotype.

(2) A physical print made by this process.

(3) A slang term for a digital rendition of the process.

(4) A slang term for such a drawing, whether blue or not.

(5) By analogy, a detailed outline or plan of action (in text or image).

(6) To make a blueprint.

(7) A technique for optimizing the performance of internal combustion engines by machining (or matching) components to their exact specifications.

1887: The construct was blue + print (blue print and blue-print (1882) were the rarely used alternative spellings).  The figurative sense of "detailed plan" dates from 1926 and use as a verb is from 1939.

Blue dates from the sixteenth century and was from the Middle English blewe, from the Anglo-Norman blew (blue), from the Frankish blāu (blue) (possibly via the Medieval Latin blāvus & blāvius (blue)), from the Proto-Germanic blēwaz (blue, dark blue), from the primitive Indo-European bhlēw (yellow, blond, grey).  It was cognate with the dialectal English blow (blue), the Scots blue, blew (blue), the North Frisian bla & blö (blue), the Saterland Frisian blau (blue), the Dutch blauw (blue), the German blau (blue), the Danish, Norwegian & Swedish blå (blue), the Icelandic blár (blue).  It was cognate also with the obsolete Middle English blee (color) related to the Welsh lliw (color), the Latin flāvus (yellow) and the Middle Irish blá (yellow). A doublet of blae.  The present spelling in English has existed since the sixteenth century and was common by circa 1700.  Many colors have in English been productive in many senses and blue has contributed to many phrases in fields as diverse as mental health (depression, sadness), semiotics (coolness in temperature), popular music (the blues), social conservatism (blue stocking; blue rinse), politics (conservative (Tory) & Whig identifiers and (unrelated) the US Democratic Party), labor-market segmentation (blue-collar), social class (blue-blood), stock market status (blue-chip) and, inexplicably, as an intensifier (blue murder).

Print dates from circa 1300 and was from the Middle English printen, prenten, preenten & prente (impression, mark made by impression upon a surface), an apheretic form of emprinten & enprinten (to impress; imprint).  It was related to the Dutch prenten (to imprint), the Middle Low German prenten (to print; write), the Danish prente (to print), the Swedish prenta (to write German letters).  The late Old French preinte (impression) was a noun use of the feminine past participle of preindre (to press, crush), altered from prembre, from the Latin premere (to press, hold fast, cover, crowd, compress), from the primitive Indo-European root per- (to strike).  The Old French word was also the source of the Middle Dutch (prente (the Dutch prent) and was borrowed by other Germanic languages.

The sense of "a printed publication" (applied later particularly to newspapers) was from the 1560s.  The meaning "printed lettering" is from the 1620s and print-hand (print-like handwriting) from the 1650s.  The sense of "picture or design from a block or plate" dates from the 1660s while the meaning "piece of printed cloth or fabric" appeared first in 1756.  The photographic sense emerged apparently only by 1853, some three decades after the first photographs, the use evolving as printed photographs became mass-market consumer products.  Print journalism seemed to have been described as such only from 1962, a form of differentiation from the work of those employed by television broadcasters.

Blueprinting internal combustion engines is the practice of disassembling the unit and machining the critical components (piston, conrods etc) to the point where they exactly meet the stated specifications (dimensions & weight).  Essentially, the process is one of exactitude, using precision tools to make components produced using the techniques of mass production (which inherently involves wider tolerances) and modifying them by using tighter tolerances, meeting exact design specifications.  It’s most associated with high-performance racing cars, especially those which compete in “standard-production” classes which don’t permit modifications to most components.  In some cases, especially with factory-supported operations, the components might be specially selected, prior to assembly.

Blueprint of the USS Missouri (BB-63), an Iowa-class battleship launched in 1944.  Missouri was the last battleship commissioned by the US Navy.

The first blueprint was developed in 1842 by English mathematician, astronomer, chemist & experimental photographer Sir John Herschel (1792-1871).  What he then termed a “cyanotype process” eliminated the need to copy original drawings by means of hand-tracing, a cumbersome, time consuming (and therefore expensive) process.  At what was then an astonishingly low cost, it permitted the rapid and accurate production of an unlimited number of copies.  The cyanotype process used a drawing on semi-transparent paper that was weighted down on top of a sheet of paper which was then placed over another piece of paper, coated with a mix of ammonium iron citrate and potassium ferrocyanide (derived from an aqueous solution and latter dried).  When the two papers were exposed to light, the chemical reaction produced an insoluble blue compound called blue ferric ferrocyanide (which became famous as Prussian Blue), except where the blueprinting paper was covered and the light was blocked by the lines of the original drawing. After the paper was washed and dried to preserve those lines, the result was a negative image of white (or whatever color the blueprint paper originally was) against a dark blue background.  White was by far the most used paper and the most common cyanotypes were thus blue with white lines.  At least by 1882 they were being described as “blue prints” but by 1887, they were almost universally called blueprints and in engineering and architecture had become ubiquitous, Herschel’s photochemical process producing copies at a tenth the cost of hand-tracing.

Refinements and economies of scale meant that during the early twentieth century the quality of blueprints improved and costs further fell but by the 1940s, they began to be supplanted by diazo prints (known also as “whiteprints” or “bluelines”).  Diazo prints were rendered with blue lines on a white background, making them easier to read and they could be produced more quickly on machinery which was simpler and much less expensive than the intricate photochemical devices blueprints demanded.  Accordingly, reprographic companies soon updated their plant, attracted too by the lower running costs, the diazo machinery not requiring the extensive and frequent maintenance demanded by the physically big and intricate photochemical copiers.

One tradition of the old ways did however endure.  The diazo machines caught on but “diazo print”, “whiteprint” & “blueline” never did; the drawings, regardless of the process used, the color of the paper or the lines (and many used black rather than blue) continued to be known as “blueprints”.  That linguistic tribute persisted even after diazo printing was phased-out and replaced with the xerographic print process, the standard copy machine technology using toner on bond paper.  Used for some time in commerce, large-size xerography machines became available in the mid-1970s and although originally very expensive, costs rapidly fell and the older printing methods were soon rendered obsolete.  As computer-aided design (CAD) software entered the mainstream during the 1990s, designs increasingly were printed directly from a computer to printer or plotter and despite the paper used being rarely blue, the output continued to be known as the blueprint.

Blueprint of the Chrysler Building, New York City, 1930.

Even now, although often viewed only as multi-colored images on screens (which might be on tablets or phones), such electronic drawings are still usually called blueprints.  Nor have blueprints vanished.  There are many things (buildings, bridges, roads, power-plants, railroads, sewers et al) built before the 1990s which have an expected life measured in decades or even centuries and few of these were designed using digital records.  The original blueprints therefore remain important to those engaged in maintenance or repair and can be critical also in litigation.  Old blueprints can be scanned and converted to digital formats but in many cases, the originals are fragile or physically deteriorated and finer details are sometimes legible only if viewed on the true blueprint.  Centuries from now, magnifying glasses in hand, engineers may still be examining twentieth century blueprints.

Rimbellisher

Rimbellisher (pronounced rhim-bell-lysh)

A decorative ring attached to the rim of a car's wheel.

1940s: A portmanteau word, the construct being rim +‎ (em)bellish +-er and originally a trademarked brand of the Ace company.  Rim was from the tenth century Middle English rim, rym & rime, from the Old English rima (rim, edge, border, bank, coast), from the Proto-Germanic rimô & rembô (edge, border), from the primitive Indo-European rem- & remə- (to rest, support, be based).   It was cognate with the Saterland Frisian Rim (plank, wooden cross, trellis), the Old Saxon rimi (edge; border; trim) and the Old Norse rimi (raised strip of land, ridge).  Rim generally means “an edge around something, especially when circular” and is used in fields a different as engineering and vulcanology.  The use in political geography is an extension of the idea, something like “PacRim” (Pac(ific) + rim) used to group the nations with coastlines along the Pacific Ocean.  The use in print journalism referred to “a semicircular copydesk”.   The special use in metallurgy described the outer layer of metal in an ingot where the composition was different from that of the centre.  The word rim is an especially frustrating one for golfers to hear because it describes the ball rolling around the rim of the hole but declining to go in.

Embellish dates from the early fourteenth century and was from the Middle English embelisshen from the Anglo-French, from the Middle French embeliss- (stem of embelir), the construct being em- (The form taken by en- before the labial consonants “b” & “p”, as it assimilates place of articulation).  The en- prefix was from the Middle English en- & in-.  In the Old French it existed as en- & an-, from the Latin in- (in, into); it was also from an alteration of in-, from the Middle English in-, from the Old English in- (in, into), from the Proto-Germanic in (in).  Both the Latin and Germanic forms were from the primitive Indo-European en (in, into) and the frequency of use in the Old French is because of the confluence with the Frankish an- intensive prefix, related to the Old English on-.) + bel-, from the Latin bellus (pretty) + -ish.  The –ish suffix was from the Middle English –ish & -isch, from the Old English –isċ, from the Proto-West Germanic -isk, from the Proto-Germanic –iskaz, from the primitive Indo-European -iskos.  It was cognate with the Dutch -s; the German -isch (from which Dutch gained -isch), the Norwegian, Danish, and Swedish -isk & -sk, the Lithuanian –iškas, the Russian -ский (-skij) and the Ancient Greek diminutive suffix -ίσκος (-ískos); a doublet of -esque and -ski.  There exists a welter of synonyms and companion phrases such as decorate, grace, prettify, bedeck, dress up, exaggerate, gild, overstate, festoon, embroider, adorn, spiff up, trim, magnify, deck, color, enrich, elaborate, ornament, beautify, enhance, array & garnish.  Embellish is a verb, embellishing is a noun & verb, embellished is a verb & adjective and embellisher & embellishment are nouns; the noun plural is embellishments.

The –er suffix was from the Middle English –er & -ere, from the Old English -ere, from the Proto-Germanic -ārijaz, thought most likely to have been borrowed from the Latin –ārius where, as a suffix, it was used to form adjectives from nouns or numerals.  In English, the –er suffix, when added to a verb, created an agent noun: the person or thing that doing the action indicated by the root verb.   The use in English was reinforced by the synonymous but unrelated Old French –or & -eor (the Anglo-Norman variant -our), from the Latin -ātor & -tor, from the primitive Indo-European -tōr.  When appended to a noun, it created the noun denoting an occupation or describing the person whose occupation is the noun.  Rimbellisher is a noun and the noun plural is rimbellishers.  All other forms are non-standard but a wheel to which a rimbellisher has been fitted could be said to be rimbellished (adjective) white the person doing the fitting would be a rimbellisher (noun), the process an act of rimbellishing (verb) and the result a rimbellishment (noun).

The Jaguar XK range (1948-1961) was available either with solid or wire wheels and while the choice was usually on aesthetic grounds, those using the things in competition sometimes had to assess the trade-offs.  The wire wheels were lighter and provided better cooling of the brakes (especially those connected to the rear wheels which were covered with fender skirts (spats) when the steel wheels were fitted.  In many forms of motor sport that was of course a great advantage but the spokes and the deletion of the skirts came at an aerodynamic cost, the additional drag induced by the combination reducing top speed by a up to 5 mph (8 km/h) and increasing fuel consumption.  It was thus a question of working out what was most valued and in the early days, where regulations permitted, some drivers used wire-wheels at the front and retained the skirts at the rear, attempting to get as much as possible of the best of both worlds (the protrusion of the hubs used on the wire wheels precluded them from fitting behind the skirts).  Jaguar XK owners would never refer to their wheels as “rims” although there may be some who have added “rims” to their modern (post Tata ownership) Jaguars.

Among certain classes, it’s now common to refer to wheels as rims, and the flashier the product, the more likely it is to be called a “rim”.  Good taste is of course subjective but as a general rule, the greater the propensity to being described as a rim, the more likely it is to be something in poor taste.  That’s unless it actually is a rim, some wheels being of multi-part construction where the rim is a separate piece (and composed sometimes from a different metal).  In the early days of motoring this was the almost universal method of construction and it persisted in trucks until relatively recently (although still used in heavy, earth-moving equipment and such).  However, those dealing with the high-priced, multi-pieced wheels seem still to call them wheels and use the term “rim” only when discussing the actual rim component.

According to the Oxford English Dictionary (OED), the first known instance of rimbellisher in print was in The Motor (1903-1988) magazine in 1949 although they seem first to have been so-described when on sale in England in 1948.  The rimbellishers were a new product for the Ace Company which in the 1930s had specialized in producing disk-like covers for wire-wheels.  That might seem strange because wire wheels are now much admired but in the 1930s many regarded them as old-fashioned although their light-weight construction meant they were often still used.  What Ace’s aluminium covers provided was the advantage of the lighter weight combined with a shiny, modernist look and they were also easy to keep clean, unlike wire wheels which could demand hours each month to maintain.

The Ace company's publicity material from the 1950s.

In the post-war years the rimbellishers became popular because they were a detail which added a “finished” look.  They were a chromed ring which attached inside the rim of the wheel, providing a contrasting band between the tyre and the centre of the wheel, partially covered usually by a hubcap.  Ace’s original Rimbellishers were secured using a worm-drive type of fastening which ensured the metal of the wheel suffered no damage but as other manufacturers entered the market, the trend became to use a cheaper method of construction using nothing more than multiple sprung tags and with the devices push-fitted into the well of the wheel, some scraping of the paint being inevitable.  Rimbellisher (always with an initial capital) was a registered trademark of the Ace company but the word quickly became generic and was in the 1950s & 1960s used to describe any similar device.  Interestingly, by the mid 1950s, Ace ceased to use “rimbellisher” in its advertising copy and described the two ranges as “wheel discs” and “wheel trims”.

The early versions did nothing more than produce a visual effect but the stylists couldn’t resist the opportunities and some rimbellishers grew to the extent they completely blocked the flow of air through the vents in the wheels and that adversely affected the cooling of the brakes, the use of some of the new generation of full-wheel covers also having this consequence.  The solution was to ensure there was some airflow but to maintain as much as possible of the visual effect, what were often added were little fins and for these to work properly, they needed to catch the airflow so there were left and right-side versions, an idea used to this day in the alloy wheels of some high-price machinery.

Ace in the early 1950s had distributers in the US and both their rimbellishers and full-wheel covers were offered.  They took advantage of the design which enabled the same basic units to be used, made specific only the substitution of a centre emblem which was varied to suit different manufacturers.  Ace’s market penetration for domestic vehicles didn’t last because Detroit soon began producing their own and within a short time they were elaborate and often garish, something which would last into the twenty-first century.  The Americans soon forgot about the rimbellisher name and started calling them trim-rings and they became a feature of the steel “sports wheels” manufacturers offered on their high-performance ranges in the years before aluminium wheels became mainstream products.  The trim-rings of course had a manufacturing cost and this was built into the price when the wheels were listed as an option.  The cost of production wouldn’t have been great but interestingly, when General Motors’ Pontiac division developed the “Judge” option for its GTO to compete with the low-cost Plymouth Road Runner, the trim-rings were among the items deleted.  However, the Judge package evolved to the point where it became an extra-cost option for the GTO with the missing trim-rings about the only visible concession to economy.

Mercedes-Benz W111s: 1959 220 SE with 8-slot rimbellishers (left), 1967 250 SE with the briefly used solid rimbellishers (centre) and 1971 280 SE 3.5 with the later 12-slot rimbellishers which lacked the elegance of the 8-slots.

Like many companies, Mercedes-Benz used wheel covers as a class identifier.  When the W111 saloons (1959-1968) were released in 1959, the entry-level 220 was fitted with just hubcaps while the up market twin-carburetor 220 S and the fuel-injected 220 SE had rimbellishers (made by the factory, not Ace).  Within a few years, the use of rimbellishers was expanded but by the mid-1960s, the elegant 8-slot units mostly had been replaced with a less-pleasing solid metal pressing (albeit one which provided a gap for brake cooling).  That didn’t last and phased-in between 1967-1968, the company switched from the hubcap / rimbellisher combination to a one-piece wheel cover which included the emulation of a 12-slot rimbellisher.  There were no objections to the adoption of one-piece construction but few found the new design as attractive as the earlier 8-slot.

MGA Coupé (left) with the rare Ace Mercury Wheel Discs (right).

Rarely seen however are the Ace Mercury Wheel Discs which were at various times a factory option also on the ZA-ZB Magnettes (1953-1958), MGB (1962-1980) and Midget (1961-1979).  The Ace Mercury was not exclusive to the MG range and was widely available from aftermarket suppliers in a variety of sizes and all that distinguished the MG units was that Ace supplied them to the factory with an octagon-shaped MG centre badge.  Some have been seen with a (fake) eared spinner in the style of a knockoff nut but these were never available from the factory.  The Mercury was made from bright anodized aluminium and thus was both lightweight and corrosion-resistant but somewhat fragile if subjected to stresses which which steel would easily cope.  The small louvers operate as air scoops when the wheels are rotating, pulling in cooling air and directing it through the holes in the wheel to assist in cooling the brakes; the set of four was thus supplied in left & right-hand pairs and needed to be installed with the louvers’ open edge “facing the breeze”.  The design was changed in 1959 when the wheels were revised and at the same time the Rimbellishers were deleted from the option list because they no longer fitted the new wheels (although third-party rimbellishers could still be used).
