Mezzanine

Mezzanine (pronounced mez-uh-neen)

(1) In architecture, a low story between two other stories of greater height in a building, especially when the low story and the one beneath it form part of one composition; an entresol (in general use referred to as “mezzanine” or “mezzanine floor”, most historically between the ground and first levels because so many were added to take advantage of the high ceilings often found in these voids.  A mezzanine is an intermediate floor (occasionally called a “sub-storey” or “demi-storey”) which does not extend over the whole floor-space below and can thus be visualized a kind of (usually large) large balcony overlooking the floor below; many were atop “grand” staircases which were often the focal point of ground floors.

(2) By extension (and used loosely), an apartment, room, restaurant etc on such an intermediate floor.

(3) In theatre (and other performance spaces) design, the lowest balcony or forward part of such a balcony (North American use and known sometimes as the “dress circle”), the seats there usually sold either at a premium or a discount against the “orchestra” seats depending on the structure.

(4) In theatre design, a space under the stage, from which contrivances such as traps are worked (obsolete).

(5) In financial markets, an intermediate stage in a financial process, known variously as “mezzanine funding”, “mezzanine capital”, or “mezzanine debt” (“mezz” the shorthand of traders).

(6) In interior design, an additional layer of flooring, laid over a floor either to raise the height, conceal imperfections or afford protection from water penetration (the latter common in server rooms & farms).

(7) As “mezzanine window”, a a small window at the height of a mezzanine floor or an attic.

(8) In computer hardware, as mezzanine board, the gender-neutral replacement term for the earlier daughter boards (which plugged into motherboards (now the gender neutral system board)

(9) In figurative use, any intermediate or ancillary stage or device (rare except in engineering (engineering) where it’s used to describe things fulfilling an intermediate or secondary function.  Curiously, software engineers & coders seem not to use the term, possibly to avoid confusion with the hardware devices.

1705–1715: From the French mezzanine & its etymon the Italian mezzanino (a low story between two higher ones in a building), from mezzano (middle (adjective) & go-between (noun)) the construct being mezzan(o) (in either sense of “middle”), from the Latin mediānus (median; of the middle) + -ino (the diminutive suffix).  Mezzano was from the Latin adjective mediānus (central, middle), from medius (mid, middle), ultimately from a construct of the primitive Indo-European root médyos or médhyo (middle)) + -ānus (the suffix meaning “of or pertaining to”).  The word was almost exclusive to architects before the early twentieth century when it came to be used on New York’s Broadway to mean “lowest balcony in a theater”, presumably because the use of something so Italianesque might justify charging a premium for the ticket.  The Italian mediānus was an element also in words like mediator (an agent who interposes between two parties), medium (that size between big & small) and medieval (a creation of Modern English from the New Latin medium aevum (the middle age, thus pertaining to or suggestive of the Middle Ages), the construct being medi(ānus) (the middle) + aev(um) (age) + -al (the Latin adjectival suffix appended to various words (often nouns) to make an adjective).  Mezzanine is a noun & adjective and mezzanining & mezzanined are verbs; the noun plural is mezzanines.  Because mezzanine was a particular specification in architecture, historically, adjectives like mezzaninesque or mezzaninish would have been absurd but given the fertile imaginations of those engineering new financial products, they may yet come into vogue.

In casual use, many refer to smaller mezzanines as balconies but architects note the latter tend to be installed on a building’s exterior while a mezzanine is inherently an indoor feature.  While the motifs of ether can be used either inside or out, by convention the indoor/outdoor convention of use dictates the choice of nomenclature.  A mezzanine is an intermediate level which is built with a partial floor which doesn’t fully cover the floor and historically many were added between the ground and first levels to take advantage of the high ceilings often found in these voids, many featuring the so-called “grand staircases” which were often the focal point of ground floors.  By contrast, a balcony is an elevated platform typically attached to the upper exterior of a building to provide a space onto which people may sit or stand for a variety of purposes.

Penta Mezzanine’s conceptual diagram of mezzanine financing.

The idea of mezzanine financing emerged in the US early in the twentieth century and is a highly variable mechanism involving a hybrid mix of debt and equity, the use of mezzanine in this context reflecting its “middle or intermediate” position between senior debt and equity in the corporate structures.  Mezzanine was a niche in US capital markets until the early post-war years when un-met demand in the gap between conventional (secured) bank loans and equity investment was identified and in the buoyant trans-Atlantic economy of the era it proved ideally suited to the increasingly popular leveraged buyouts (LBOs) and mergers & acquisitions (M&A) because of the flexibility and the acceptance of subordinated forms of capital.  By later standards the use of mezzanine instruments was on a small scale but the techniques developed lad the basis for the boom in corporate financing which flared in the newly deregulated environment of the 1980s and 1990s when the volume LBOs & M&A activity was such that some institutions were able to devote entire divisions to service the market.

Mezzanine financing is now part of financial industry in just about every developed economy and provides a source of capital combines debt and equity, almost always at a higher cost than traditional arrangements so while not regarded as a “last resort” in the way that term in used in banking, the device exists to fill the shortfall (ie the bit “in the middle”) between need and what conventional sources decide is justified by the risk.  Demanding (1) a premium interest rate to provide capital which is subordinated to other debts in the case of liquidation or bankruptcy & (2) taking an equity position are the ways the risk-reward math can be made to work for both parties and mezzanine financing continues to exists because it fulfills a need, thus ensuring there is both supply & demand to sustain the model.

1300-1350: From the Middle English closet (a small private room for study or prayer), from the Old French closet (small enclosure, private room), the construct being clos (private space; enclosure) +‎ -et (the suffix used to form diminutives), from the Latin clausum (closed space, enclosure, confinement), the neuter past participle of claudere (to shut).  In French, it tended to be applied to small, open-air enclosures.  The suffix –et was from the Middle English -et, from the Old French –et & its feminine variant -ette, from the Late Latin -ittus (and the other gender forms -itta & -ittum).  It was used to form diminutives, loosely construed.  Some European languages picked up the Old French spelling while others used variations including Czech (klozet) & Spanish (clóset).  Closets can be tiny or fair-sized rooms so the appropriate synonym depends on context and architecture and might include: cabinet, container, locker, room, vault, wardrobe, bin, buffet, depository, receptacle, recess, repository, safe, sideboard, walk-in, ambry, chest of drawers & cold storage.  Closet is a noun, verb & adjective, closeting is a verb (which some dispute) & adjective (plural closets) and closeting is a noun & verb.  The noun plural is closets.

The adjective dates from the 1680s in the sense of “private, done in seclusion”, extended by 1782 as "fitted only for scholarly seclusion, not adapted to the conditions of practical life" (ie in the sense of the “ivory tower”).  The meaning "secret, not public, unknown" was first applied to alcoholism in the early 1950s but by the 1970s had come to be used principally of homosexuality.  This, and the earlier forms (closet anarchist, closet alcoholic, closet Freemason, closet smoker et al) were all based on the idiomatic “skeleton in the closet” (which existed also as “skeleton in the cupboard”), describing some undisclosed fact which, if revealed would cause reputational damage (or worse) to a person.  Literally, the imagery summoned was of someone with a human corpse secreted in a closet in their house, one which had sat there so long the flesh had decomposed to the bone.  The earliest known appearance in print was in 1816 but it’s not known how long it’d been in oral use and it usually implied culpability for some serious offence though not necessarily anything involving a corpse.

The phrase “come out of the closet” (admit something openly) was first recorded 1963 and the use rapidly became exclusive to homosexuals and lent a new meaning to the word “out”.  This meaning itself became nuanced: “To come out” (openly avowing one's homosexuality) emerged as a phrase in the 1960s and was an overtly political statement (obviously different from the earlier “a confessed homosexual” whereas “outing” and “outed” came to be used in the 1970s to refer to people making the homosexuality of others public knowledge.  Outing became controversial because of the argument (made sometimes by those within the gay community) that it was justified if exposing hypocrisy (usually a conservative politician who publicly condemned homosexuality while in private indulging in the practice).  In Spanish use (most notably in Latin America) the noun clóset is used to refer to the state of being secretly gay (from salir del clóset), the plural being clósets.

The verb closet (shut up as in a closet) was originally usually for purposes of concealment or private consultation and dates from the 1680s.  The water closet (WC and described also in the delightful phrase “closet of ease”) was the ancestor of the familiar modern loo (toilet; lavatory; privy with a waste-pipe and means to carry off the discharge by a flush of water), the term first used in 1755 and later perfected by the famous plumber, Mr Thomas Crapper.  The phrase “walk-in” was used first in the 1890s as a slang term by hotel check-in clerks to refer to those arriving without a reservation (it’s now a standard statistical category in hotels) and by 1928 was used in many forms of commerce to mean “customer who arrived without an appointment”.  The “walk-in closet” was first advertised in the US in 1946 where it described a built-in wardrobe large enough to walk into, some equipped with mirrors, tables, chairs etc).

The Gay Bob Doll

Gay Bob with man-bag.

There’s evidence that for much of human existence, homosexuality has been at least widely tolerated and often accepted but in the West, under the influence of the Christian churches, it came to attract much disapprobation though even in the nineteenth century there were those who (without much success) campaigned for legislative and social change, the odd self-declared homosexual sometimes urging others to out themselves.  However, it wasn’t until the 1960s that the still embryonic “gay liberation” movement understood that “coming out en masse” was of importance because with critical mass came political influence.  Social attitudes did change and it was perhaps an indication of acceptance that in 2005 the cartoon show South Park could run an episode called Trapped in the Closet in which the Scientologist film star Tom Cruise (b 1962) refuses to come out of a closet.  Not discouraged by the threat of writs, South Park later featured an episode in which the actor worked in a confectionery factory packing fudge.  Attitudes and legislative changes didn't always move in unison and things unfolded gradually but that process was still incomplete when, in 1977, the Gay Bob doll was released.

Clothes and accessories were available, including those for dressing the “gay farmer”.

The winds of change were clearly blowing by 1977 because in that year Harvey Milk (1930–1978; member of the San Francisco Board of Supervisors, 1978) became the first openly gay man elected to public office in California (and it’ll never be known how many of his predecessors were still in the closet).  However, if Milk was out of the closet, Gab Bob came neatly packaged in his own (cardboard) closet buyers able to out him and put him back as required.  Designed to look like popular film stars of the era, Gay Bob’s creator described the doll as perfect for “…an executive’s desk, dash board ornament, the attaché case, the bathtub rim or a health club gym bag”, a notable feature was the doll’s “anatomical correctness”, presumably a sales feature but one which necessitated production being out-sourced to Hong-Kong because US manufacturers declined the contract. 

Gay Bob stepping out of the closet.

Just so there were no misunderstandings, Gay Bob was supplied with a fashion catalog which contained an explanation:  Hi boys, girls and grownups, I’m Gay Bob, the world’s first gay doll.  I bet you are wondering why I come packed in a closet. “Coming out of the closet” is an expression which means that you admit the truth about yourself and are no longer ashamed of what you are.  Gay people are no different than straight people.  If everyone came out of their closets, there wouldn’t be so many angry, frustrated, frightened people.  It’s not easy to be honest about what you are, in fact it takes a great deal of courage.  But remember, if Gay Bob has the courage to come out of his closet, so can you!

Popular since the nineteenth century, mail-order was the on-line shopping of the analogue era.

Conservative activists were of course appalled by Gay Bob, his anatomical correctness and his threateningly optimistic message, describing it all as “a threat to family values” and more “…evidence of the desperation the homosexual campaign has reached in its effort to put homosexual lifestyle, which is a death style, across to the American people”.  The forces of capitalism either agreed or were unwilling to risk a backlash because attempts have the big department stores stock Gay Bob on their shelves were unsuccessful so the doll was sold via mail order, advertisements placed in gay magazines.  One doll cost US$19.50 (including shipping and handling within the US) while a pair could be purchased at a discounted US$35 (and to take advantage of the anatomical correctness, buying a brace was presumably in vogue.  Over two thousand were sold within months and in liberal New York and San Francisco, some boutiques would later carry the product.  Something of a footnote to the LGBTQQIAAOP timeline, Gay Bob is a now a collector’s item, examples in good condition realizing over US$200 at on-line auction sites and of course, those with a pristine, un-violated closet will command a premium.

Ping

Ping (pronounced ping)

(1) To produce a short, high-pitched resonant sound, like that of a bullet striking a sheet of metal (as a verb used without object).

(2) In computing, to send an echo-request packet to an IP address and use the echo reply to determine whether another computer on the network is operational and the speed at which the data is being transferred.

(3) Informally, to make contact with someone by sending a brief electronic message (text messages and later variations).  A ping can also be a notification in response to a message.

(4) A pinging sound.

(5) An infrasonic or ultrasonic sound wave created by sonar in echolocation or an acoustic signal transmitted to indicate a location.

(6) The Lord Chancellor, one of the courtiers in Giacomo Puccini's (1858-1924), opera Turandot (1926).

(7) In colloquial use, to flick something, usually with a finger-tip.

(8) In colloquial use, to be detected committing an offence (by a police officer, an umpire or referee) and subsequently penalized.

(9) In internal combustion engines (also referred to as pinking, knocking or detonation), when the combustion of the fuel/air mixture in the cylinder does not begin correctly in response to ignition by the spark plug.  The usual form in this context is the adjective "pinging".

1835: Partly onomatopoeic (imitative of the sound of a bullet whistling through the air or striking something sharply) and partly reflecting the influence of the (continuing) Middle English pingen (to push, shove, pierce, stab, prod, goad, urge, feel remorse, incite), from the Old English pyngan (to prick); used as a verb since 1855.  The meaning "short, high-pitched electronic pulse" is attested from 1943, the reference being to the sonar systems used on both submarines and surface vessels.  The noun plural was pings, the present participle pinging, the past participle pinged.  The non-standard forms are pang & pung (past participle) although one can understand why those learning English might assume they should exist.  Pingdemic was an invention of computer programmers.

The noun ping-pong was also based on sound and dates from 1901 as Ping-Pong, the trademark for table tennis equipment registered by Parker Brothers, both words imitative of the sound of the ball hitting a hard surface (said by some to have been attested since 1823; the game was much in vogue in the US 1900-1905.  In the figurative sense of "move or send back and forth without progress, resolution, or purpose", use dates from 1952, later extended (though a little more hopefully) to “ping-pong diplomacy” which referred to the US and the PRC (Communist China) agreeing to exchange ping-pong teams before sending diplomats.  The electronic arcade game “Pong” (1972) was an abbreviation of ping-pong although there is evidence pong had for some years been a truncated reference to the game proper.

Example of using ping to identify the ip address using the host name.

Ping is one of a small subset of commands which constitute the lingua franca of computer network administration software, included in almost all network tool bundles regardless of the local or network operating systems.  It is a utility which tests the connectivity and speed of a host running on any Internet Protocol (IP) network by measuring the round-trip time for messages sent from the originating host to a destination computer, echoed back to the source.  Originally run exclusively from a command prompt, GUI (graphical user interface) versions have long been available and are handy for infrequent users who have never needed to memorize the syntax.  Ping sends Internet Control Message Protocol (ICMP) echo request packets to the target host and waits for an ICMP echo reply, reporting errors, packet loss, and a statistical summary of the results, most usefully the duration (in milliseconds) of the minimum, maximum & mean round-trips.

The name ping was a borrowing from naval sonar terminology that sends a pulse of sound and listens for the echo to detect objects under water to determining their location, direction and speed.  The sonar systems used at sea included audible pings and some computer ping utilities include one as a novelty.  The original software was a Q&D (quick & dirty) utility created in 1983 to diagnose tiresome problems on a network, the name chosen because the method was analogous with sonar's echolocation.  The occasionally mentioned Packet InterNet Groper is a backronym created some years after the first versions of ping were distributed.

Turandot

Turandot (1926) was Giacomo Puccini's (1858-1924) last opera and one which remained uncompleted at his death.  Puccini based the opera on the play Turandot (1762) by Venetian playwright Count Carlo Gozzi (1720–1806) which borrowed from one of the seven stories in the epic-length work by Persian poet Nizami (circa 1141–1209), the motif of seven aligned with the days of the week, the Persian seven-color scheme and the seven planets at that time known.  Turandot as told by Nizami is the story attached to Tuesday, the protagonist a Russian princess (Turan-Dokht (daughter of Turan)), a name often used in Persian poetry for Central Asian princesses.  Puccini seems to have moved the site of his Opera to China for no reason other than his interest in incorporating into the work Chinese musical themes, much as he’d been attracted to Japanese sounds for his earlier Madama Butterfly (1904).  Most people on the planet have never heard of Puccini and his operas but many will be at least vaguely familiar with one fragment of Turandot, Nessun dorma (Let no one sleep), among the most famous of the tenor arias, because of the global broadcast of a performance during the 1990 FIFA World Cup.

Puccini completed the three-act structure before his death and it was in this form it was first performed at La Scala in Milan in April 1926, conducted by Arturo Toscanini (1867-1957), the conductor refusing to go beyond the point where Puccini stopped.  With an ending added by Franco Alfano (1875-1954), it was presented again the very next evening but performances have varied over the years, a few sticking to the original, some using one of the variations written by Alfano and others with different ending entirely, some better received than others.  Opera buffs and professional musicians have always been drawn to Turandot because it’s Puccini at his most musically innovative but audiences have never embraced it quite as they did the seductive butterfly which is a set-piece love story packed with melodies.  However, it’s now viewed also through a political lens, the specter of cultural appropriation and accusation of racial stereotyping looming over every aria.

From various stage productions: Ping, Lord Chancellor (baritone), Pang, Chief Steward of the Imperial Household (tenor) & Pong, Executive Chef of the Imperial Kitchen (tenor) are the triumvirate of courtiers in Puccini's Turandot.

The critique is that the depiction of a barbaric Chinese princess is an outdated orientalist construct of Chinese people and the idea of white people dressing and being made up as caricatures of those from the far east goes beyond mere cultural appropriation, the use of Chinese music, traditional dress and the perpetuating historical Western imagery being demeaning.  Beyond that, white audiences who are either oblivious to these concerns or dismissive of them are (at the very least) guilty of committing microaggressions and are casually asserting cultural superiority, if not actual white supremacy.

Nail

Nail (pronounced neyl)

(1) A slender, typically rod-shaped rigid piece of metal, usually in many lengths and thicknesses, having (usually) one end pointed and the other (usually) enlarged or flattened, and used for hammering into or through wood, concrete or other materials; in the building trades the most common use is to fasten or join together separate pieces (of timber etc).

(5) A measure for a length for cloth, equal to 2¼ inches (57 mm) or 1⁄20 of an ell; 1⁄16 of a yard (archaic); it’s assumed the origin lies in the use to mark that length on the end of a yardstick.

(6) To fasten with a nail or nails; to hemmer in a nail.

(7) To enclose or confine (something) by nailing (often followed by up or down).

Pre 900: From the Middle English noun nail & nayl, from the Old English nægl and cognate with the Old Frisian neil, the Old Saxon & Old High German nagal, the Dutch nagel, the German Nagel, the Old Norse nagl (fingernail), all of which were from the unattested Germanic naglaz.  As a derivative, it was akin to the Lithuanian nãgas & nagà (hoof), the Old Prussian nage (foot), the Old Church Slavonic noga (leg, foot), (the Serbo-Croatian nòga, the Czech noha, the Polish noga and the Russian nogá, all of which were probably originally a jocular reference to the foot as “a hoof”), the Old Church Slavonic nogŭtĭ, the Tocharian A maku & Tocharian B mekwa (fingernail, claw), all from the unattested North European Indo-European ənogwh-.  It was further akin to the Old Irish ingen, the Welsh ewin and the Breton ivin, from the unattested Celtic gwhīnā, the Latin unguis (fingernail, claw), from the unattested Italo-Celtic əngwhi-;the Greek ónyx (stem onych-), the Sanskrit ághri- (foot), from the unattested ághli-; the Armenian ełungn from the unattested onogwh-;the Middle English verbs naile, nail & nayle, the Old English næglian and cognate with the Old Saxon neglian, the Old High German negilen, the Old Norse negla, from the unattested Germanic nagl-janan (the Gothic was ganagljan).  The ultimate source was the primitive Indo-European h₃nog- (nail) and the use to describe the metal fastener was from the Middle English naylen, from the Old English næġlan & nægl (fingernail (handnægl)) & negel (tapering metal pin), from the Proto-Germanic naglaz (source also of Old Norse nagl (fingernail) & nagli (metal nail).  Nail is a noun & verb, nailernailless & naillike are adjectives, renail is a verbs, nailing is a noun & vern and nailed is a verb & adjective; the noun plural is nails.

Nail is modified or used as a modifier in literally dozens of examples including finger-nail, toe-nail, nail-brush, nail-file, rusty-nail, garden-nail, nail-fungus, nail-gun & frost-nail.  In idiomatic use, a “nail in one's coffin” is a experience or event that tends to shorten life or hasten the end of something (applied retrospectively (ie post-mortem) it’s usually in the form “final nail in the coffin”.  To be “hard as nails” is either to be “in a robust physical state” or “lacking in human feelings or without sentiment”. To “nail one's colors to the mast” is to declare one’s position on something.  Something described as “better than a poke in the eye with a rusty nail” is a thing, which while not ideal, is not wholly undesirable or without charm.  In financial matters (of payments), to be “on the nail” is to “pay at once”, often in the form “pay on the nail”.  To “nail something down” is to finalize it. To have “nailed it” is “to perfectly have accomplished something” while “nailed her” indicates “having enjoyed sexual intercourse with her”.  The “right” in the phrase “hit the nail right on the head” is a more recent addition, all known instances of use prior to 1700 being “hit the nail on the head” and the elegant original is much preferred.  It’s used to mean “correctly identify something or exactly to arrive at the correct answer”.  Interestingly, the Oxford English Dictionary (OED) notes there is no documentary evidence that the phrase comes from “nail” in the sense of the ting hit by a hammer.

Double-headed nails are used for temporary structures like fencing.  When the shaft is hammered in to the point where the surface of the lower head is flat against the surface of that into which it's being hammered, it leaves the upper head standing proud with just enough of the shaft exposed to allow a claw-hammer to be used to extract nail.  There is a story that as part of an environmental protest against the building or demolition of some structure (the tales vary), activists early one morning went to the temporary fencing around the contested site and hammered in all the double-headed nails.  This is believed to be an urban myth.

The sense of “fingernail” appears to be the original which makes sense give there were fingernails before there were spikes (of metal or any other material) used to build stuff.  The verb nail was from the Old English næglian (to fix or fasten (something) onto (something else) with nails), from the Proto-Germanic ganaglijan (the source also of the Old Saxon neglian, the Old Norse negla, the Old High German negilen, the German nageln and the Gothic ganagljan (to nail), all developed from the root of the nouns.  The colloquial meaning “secure, succeed in catching or getting hold of (someone or something)” was in use by at least the 1760; hence (hence the law enforcement slang meaning “to effect an arrest”, noted since the 1930s.  The meaning “to succeed in hitting” dates from 1886 while the phrase “to nail down” (to fix in place with nails) was first recorded in the 1660s.

As a noun, “nail-biter” (worrisome or suspenseful event), perhaps surprisingly, seems not to have been in common use until 1999 an it’s applied to things from life-threatening situations to watching close sporting contests.  The idea of nail-biting as a sign of anxiety has been in various forms of literature since the 1570s, the noun nail-biting noted since 1805 and as a noun it was since the mid-nineteenth century applied to those individuals who “habitually or compulsively bit their fingernails” although this seems to have been purely literal rather than something figurative of a mental state.  Now, a “nail-biter” is one who is “habitually worried or apprehensive” and they’re often said to be “chewing the ends of their fingernails” and in political use, a “nail biter” is a criticism somewhat less cutting than “bed-wetter”.  The condition of compulsive nail-biting is the noun onychophagia, the construct being onycho- (a creation of the international scientific vocabulary), reflecting a New Latin combining form, from the Ancient Greek ὄνυξ (ónux) (claw, nail, hoof, talon) +‎ -phagia (eating, biting or swallowing), from the Ancient Greek -φαγία (-phagía).  A related form was -φαγος (-phagos) (eater), the suffix corresponding to φαγεῖν (phageîn) (to eat), the infinitive of ἔφαγον (éphagon) (I eat), which serves as aorist (essentially a compensator for sense-shifts) (for the defective verb ἐσθίω (esthíō) (I eat).  Bitter-tasting nail-polish is available for those who wish to cure themselves.  Nail-polish as a product dates from the 1880s and was originally literally a clear substance designed to give the finger or toe-nails a varnish like finish upon being buffed.  By 1884, it was being sold as “liquid nail varnish” including shads of black, pink and red although surviving depictions in art suggests men and women in various cultures have for thousands of years been coloring their nails.  Nail-files (small, flat, single-cut file for trimming the fingernails) seem first to have been sold in 1819 and nail-clippers (hand-tool used to trim the fingernails and toenails) in 1890.

The expression "nail down the lid" is a reference to the lid of a coffin (casket), the implication being one wants to make doubly certain anyone within can't possible "return from the dead".  The noun doornail (also door-nail) (large-headed nail used for studding batten doors for strength or ornament) emerged in the late fourteenth century and was often used of many large, thick nails with a large head, not necessarily those used only in doors.  The figurative expression “dead as a doornail” seems to be as old as the piece of hardware and use soon extended to “dumb as a doornail” and “deaf as a doornail).  The noun hangnail (also hang-nail) is a awful as it sounds and describes a “sore strip of partially detached flesh at the side of a nail of the finger or toe” and appears in seventeenth century texts although few etymologists appear to doubt it’s considerably older and probably a folk etymology and sense alteration of the Middle English agnail & angnail (corn on the foot), from the Old English agnail & angnail.  The origin is likely to have been literally the “painful spike” in the flesh when suffering the condition.  The first element was the Proto-Germanic ang- (compressed, hard, painful), from the primitive Indo-European root angh- (tight, painfully constricted, painful); the second the Old English nægl (spike), one of the influences on “nail”.  The noun hobnail was a “short, thick nail with a large head” which dates from the 1590s, the first element probably identical with hob (rounded peg or pin used as a mark or target in games (noted since the 1580s)) of unknown origin.  Because hobnails were hammered into the leather soles of heavy boots and shoes, “hobnail” came in the seventeenth century to be used of “a rustic person” though it was though less offensive than forms like “yokel”.

In the 1930s, the straight-8 became a favorite for manufacturers of luxury cars, attracted by its ease of manufacture (components and assembly-line tooling able to be shared with straight-sixes), the mechanical smoothness inherent in the layout and the ease of maintenance afforded by the long, narrow configuration.  However, the limitations were the relatively slow engine speeds imposed by the need to restrict the “crankshaft flex” and the height of the units, a product of the long strokes used to gain the required displacement.  By the 1950s, it was clear the future lay in big-bore, overhead valve V8s although the Mercedes-Benz engineers, unable to forget the glory days of the 1930s when the straight-eight W125s built for the Grand Prix circuits generated power and speed Formula One wouldn’t again see until the late 1970s, noted the relatively small 2.5 litre (153 cubic inch) displacement limit for 1954 and conjured up a quixotic final fling for the layout.  Used in both Formula One as the W196R and in sports car race as the W196S (better rememberd as the 300 SLR) the new 2.5 & 3.0 litre (183 cubic inch) straight-8s, unlike their pre-war predecessors, solved the issue of crankshaft flex by locating the power take-off at the centre, adding mechanical fuel-injection and a desmodromic valve train to make the things an exotic cocktail of ancient & modern.  Dominant during 1954-1955 in both Formula One & the Sports Car Championship, they were the last of the straight-8s.

Across the Atlantic, the US manufacturers also abandoned their straight-8s.  Buick introduced their overhead valve (OHV) V8 in 1953 but, being much wider than before, the new engine has to be slimmed somewhere to fit between the fenders; it would not be until later the platform was widened.  To achieve this, the engineers narrowed the cylinder heads, compelling both an conical (the so-called “pent-roof”) combustion chamber and an arrangement in which the sixteen valves pointed directly upwards on the intake side, something which not only demanded an unusual pushrod & rocker mechanism but also limited the size of the valves.  So, the valves had to be tall and narrow and, with some resemblance to nails, they picked up the nickname “nail valves”, morphing eventually to “nailhead” as a description of the whole engine.  The valve placement and angle certainly benefited the intake side but the geometry compromised the flow of exhaust gases which were compelled through their anyway small ports to make a turn of almost 180^o on their way to the tailpipe.

It wasn't the last time the head design of a Detroit V8 would be dictated by considerations of width.  When Chrysler in 1964 introduced the 273 cubic inch (4.5 litre) V8 as the first of its LA-Series (that would begat the later 318, 340 & 360 as well as the V10 made famous in the Dodge Viper), the most obvious visual difference from the earlier A-Series V8s was the noticeably smaller cylinder heads.  The A engines used as skew-type valve arrangement in which the exhaust valve was parallel to the bore with the intake valve tipped toward the intake manifold (the classic polyspherical chamber).  For the LA, Chrysler rendered all the valves tipped to the intake manifold and in-line (as viewed from the front), the industry’s standard approach to a wedge combustion chamber.  The reason for the change was that the decision had been taken to offer the compact Valiant with a V8 but it was a car which had been designed to accommodate only a straight-six and the wide-shouldered polyspheric head A-Series V8s simply wouldn’t fit.  So, essentially, wedge-heads were bolted atop the old A-Series block but the “L” in LA stood for light and the engineers wanted something genuinely lighter for the compact (in contemporary US terms) Valiant.  Accordingly, in addition to the reduced size of the heads and intake manifold, a new casting process was developed for the block (the biggest, heaviest part of an engine) which made possible thinner walls.

The nailhead wasn’t ideal for producing ultimate power but it did lend itself to prodigious low-end torque, something much appreciated by Buicks previous generation of buyers who has enjoyed the low-speed responsiveness of the famously smooth straight-8.  However, like everybody else, Buick hadn’t anticipated that as the 1950s unfolded, the industry would engage in a “power race”, something to which the free-breathing Cadillac and Chrysler’s Hemis were well-suited.  The somewhat strangulated Buick Nailhead was not at all suited and to gain power the engineers were compelled to add high-lift, long-duration camshafts which enabled the then magic 300 horsepower number to be achieved but at the expense of smoothness and tales of Buick buyers returning to the dealer to fix the “rumpity-rump” idle became legion.  Still, the Nailhead was robust, relatively light and offered what was then a generous displacement and the ever inventive hot-rod community soon worked out the path to power was to use forced induction and reverse the valve use, the supercharger blowing the fuel-air mix through the exhaust ports and the exhaust gases through the larger intake ports.  Thus the for a while Nailhead enjoyed a career as a niche player although the arrival in the mid 1950s of the much more tunable Chevrolet V8s ended the vogue for all but a few devotees who continued use well into the 1960s.  Buick acknowledged reality and, unusually, instead of following the industry trend and drawing attention to cubic inch displacement and horsepower, publicized their torque output, confusing some (though probably not Buick buyers who were a loyal crew).

Lockheed SR-71 Blackbird (1964-1999).

Not confused was the United States Air Force (USAF) which was much interested in power for its aircraft but also had a special need for torque on the tarmac and that briefly meant another small niche for the Nailhead.  The Lockheed SR-71 Blackbird (1964-1979) was a long-range, high-altitude supersonic (Mach 3+) aircraft used by the (USAF) for reconnaissance between 1966-1998 and by the National Aeronautics & Space Administration (NASA) for observation missions as late as 1999.  Something of a high-water mark among the extraordinary advances made in aeronautics and materials construction during the 1950s & 1960s, the SR-71 used the Pratt & Whitney J58 turbojet engine which used an innovative, secondary air-injection system to the afterburner, permitting additional thrust at high speed.  The SR-71 still holds a number of altitude and speed records and Lockheed’s SR-72, a hypersonic unmanned aerial vehicle (UAV) is said to be in an “advanced stage” of design and construction although whether any test flights will be conducted before 2030 remains unclear, the challenges of sustaining in the atmosphere velocities as high as Mach 6+ onerous given the heat generated.

At the time, the SR-71 was the most exotic aircraft on the planet but during testing and early in its career, to fly, it relied on a pair of even then technologically bankrupt Buick Nailhead V8s.  These were mounted in a towed cart and were effectively the turbojet’s starter motor, a concept developed in the 1930s as a work-around for the technology gap which emerged as aero-engines became too big to start by hand but no on-board electrical systems were available to trigger ignition.  The two Nailheads were connected by gears to a single, vertical drive shaft which ran the jet up to the critical speed at which ignition became self-sustaining.  The engineers chose the Nailheads after comparing them to other large displacement V8s, the aspect of the Buicks which most appealed being the torque generated at relatively low engine speeds, a characteristic ideal for driving an output shaft.  After the Nailhead was retired in 1966, later carts used Chevrolet big-block V8s but in 1969 a pneumatic start system was added to the infrastructure of the USAF bases from which the SR-71s most frequently operated, the sixteen-cylinder carts relegated to secondary bases the planes rarely used.
