Acronym

Acronym (pronounced ak-ruh-nim)

In linguistics, a word formed from the initial letters or groups of letters of words in a set phrase or series of words and pronounced as a separate word (and thus distinguished from an initialism in which the letters are pronounced separately; there are hybrids which combine both methods).

1943: The construct was acr- + -onym.  It was borrowed from the German Akronym, constructed from the Ancient Greek ἄκρον (ákron) (end, peak) + ὄνυμα (ónuma) (name), deconstructed as acr(o)- (high; beginning) +‎ -onym (name) and on the model of the German nouns Homonym & Synonym, first attested in German in the early 1900s and in English in 1940 (although the linguistic practice predated this by at least several decades).  The nouns acronymophilia (an abnormal liking or tendency for the use of acronyms), acronymania (the enthusiastic creation and use of acronyms) and acronymophobia (morbid fear or dread of acronyms) are deployed (usually) in humor.  Those exhibiting symptoms of acronymophilia or acronymania (beyond being a mere acronymist) are likely suffering from acronymitis.  Acronym is a noun & verb, acronymed is a verb, acronymic & acronymous are adjectives and acronymically is an adverb; the noun plural is acronyms.

The acronym is a one of a number of subsets in what are known as “curtailed words”.  Quite when the first acronym was used isn’t known but the habits of people do suggest it’s likely something ancient and there are folk etymologies which offer acronymic expansions for common words including “fuck” “posh” & “shit” but they’re all undocumented and the earliest known use in English was a form of the Arabic أبجد (ʔabjad), the term for the traditional ordering of the Arabic script (from the first four letters: أ (ʔ), ب (b), ج (j), د (d)).  It was the twentieth century in which the acronym multiplied, earlier antipodean contributions including ANZAC (Australian and New Zealand Army Corps) and QANTAS (Queensland and Northern Territory Aerial Services) which soon became the word Qantas, an unusual example in English of a “q” not being followed by a “u”.  Such words do appear in English language texts but they tend to be foreign borrowings including (1) qat (or khat) (a plant native to East Africa and the Arabian Peninsula, often chewed for its stimulant effects, (2) qi (a term from Chinese philosophy referring to life force or energy), qibla (the direction Muslims face when praying, towards the Kaaba in Mecca and (4) qiviut (the soft under-wool of the musk-ox, valued when making warm clothing).

Other acronyms followed ANZAC but it was the upsurge in military activity during World War II (1939-1945) which saw the creation of literally thousands, some to endure, some to be rendered obsolete by circumstances or changes in technology and some genuine one-offs such as PLUTO (Pipeline under the ocean and originally P.L.U.T.O.).  PLUTO really should have been PLUTC because the many lines ran on the floor of the English Channel between England & France as a way of pumping fuel to the beachhead established by the D-Day landings (6 Jun 1944) but PLUTC obviously had little appeal so PLUTO it was.  While a clever idea, problems with the couplings meant the volumes achieved never came close to reaching what was theoretically possible.  The terms acronym, abbreviation and initialism are often used interchangeably, but they have distinct meanings:

Acronym: (a general term for a shortened form of a word or phrase): An acronym is a type of abbreviation where the initial letters of a phrase are taken to form a new word (or one which duplicates an existing word and, not uncommonly, an earlier acronym) which is pronounced as one would a single word (although in commercial use, the pronunciation can be non-standard).  Examples of well known acronyms include “NASA” (National Aeronautics and Space Administration), “Laser” (Light Amplification by Stimulated Emission of Radiation) and “UNESCO” (United Nations Educational, Scientific and Cultural Organization”.

Abbreviation (a general term for a shortened form of a word or phrase): An abbreviation is a shortened form of a word or phrase used to represent the full version.  Abbreviations can include acronyms and initialisms, but they can also be simple clippings, truncations or contractions and common examples include “Dr” (Doctor), “Prof” (Professor) and “Thu” (Thursday).

Initialism (An abbreviation where each letter is pronounced separately): An initialism is specific type of abbreviation formed from the first letters of a phrase, but unlike acronyms, each letter is pronounced separately.  Well-known initialisms include “CIA” (Central Intelligence Agency), “UAE” (United Arab Emirates) and “WHO” (World Health Organization).

Leslie Nielsen (1926-2010) ) in one of his muddles as President Harris, addressing the General Assembly (GA) of the United Nations (UN), treating an initialism as an acronym, Scary Movie 4 (2006).

The WHO is an example of the way in which the oral use of acronyms, abbreviations & initialisms evolves by way of practice and habit rather than defined rules or convention.  Obviously, in speech, once could speak of “the who” but it’s never done, the name always expressed in full which is most among the notoriously lazy speakers of the English language who tend usually to prefer the shortest form.  Perhaps it’s felt there could be some ambiguity using the word “who” for such a purpose although that seems a thin argument and it may be there was a sense “the who” might be thought flippant although initialisms are common replacements for formal terms; HMG (his (or her) Majesty’s government) is a standard in Whitehall and Westminster while JPII & JP2 routinely appeared in Vatican documents to refer to John Paul II (1920–2005; pope 1978-2005).  Sometimes, the reason dictating the choice between spelling out the letters or forming a word is obvious:  The Bougainville Revolutionary Army was an armed secessionist movement formed in 1988 by some inhabitants of Bougainville Island who sought independence from Papua New Guinea (commonly referred to as PNG) and the group was always spoken of as the initialism the “bee-ah-eh” rather than the “Bra”, the latter definitely inappropriate.  By contrast, the armed Basque separatist organization Euskadi Ta Askatasuna (“Basque Homeland and Liberty” or “Basque Country and Freedom; active 1959-2018) was always used as an acronym (pronounced et-ah rather than ey-tuh).

The BRA and the bra, not to be confused: Francis Ona (b circa 1953–2005; Bougainville secessionist leader) with fighters from the BRA (Bougainville Revolutionary Army) (left) and Lindsay Lohan in demi-cup bra, Terry Richardson (b 1965) photo-shoot for Love Magazine, 2012.  Of the military formation, BRA is an acronym while as a abbreviation, under ISO 3166-1, it's the alpha-3 country code for Brazil.  Bra is also an abbreviation which has become an English noun; it was a clipping of brassiere, from the French brassière (in the sense it was used of a camisole-like garment).  The French brassière was a singular form which is why in English one buys "a bra" rather than the "pair of bras" one would expect on the model of "pair of spectacles", pair of gloves" etc.

Sometimes though there is inventiveness.  In 1964 the Ford Motor Company released a version of their 427 cubic inch (7.0 litre) FE V8 which featured a then novel (for Detroit) single overhead camshaft.  In industry parlance such a configuration was a “SOHC” but there was no accepted way to pronounce that a stand-alone word so the slang became “cammer” but others saw the possibility in Sohc and decided it was the “sock” so it was both an initialism and an acronym.  Acronyms can also be confused with something else.  In July 1968, John Gorton (1911-2002; Australian prime-minister 1968-1971), conducting a press conference in Djakarta (now Jakarta), was asked a question about “…general SEATO attitudes…” (SEATO was the South East Asian Treaty Organisation, a regional security arrangement (which included the UK & USA); it was created in 1954 but had become moribund years before its dissolution in 1977) to which he replied “Who’s this General Seato?”  The tale is not believed apocryphal.

There is no universal convention (an certainly no “rule”) about whether acronyms are written in upper case (NATO; UNESCO), lower case (radar, scuba) or camel case (a combination of both) (ChiPs) and the best advice is probably to follow to practice of the manufacturer, institution etc or follow one’s preferred style guide.  Quite how these practices evolve varies with the acronym, the most significant influence apparently the subjective sense of how anacronymic they’re perceived to have become and there’s also some evidence of regionalism; historically the US style guides tended to recommend all upper case for pronounced acronyms of four or fewer letters (NATO) while in the UK there was a preference to use the conventions of standard English (Nato) but the such is the US influence on the language that the upper case form is becoming more dominant.  Acronyms formed from beginning syllables are sometimes written in camel case (EpiPen) which appals some but in many cases they’re registered trademarks and that dictates what is correct; in the IT industry the mix of upper & lower case in all sorts of words has for decades been prevalent and such is the apparent randomness that the mix can’t be predicted.  Often “minor” words (“of”; “the”; “and” et al) are represented in lower case but this is not universal so “Out of Order” might appear either as “OOO” of “OoO”.  One thing which does seem to thankfully (mostly) to have vanished is the full stop (period) between letters; U.S.A. demanding a pointless additional three keystrokes.
