Acronym
An acronym is an abbreviation formed using the initial letters of a multi-word name or phrase. Acronyms are often spelled with the initial letter of each word in all caps with no punctuation.
In English, the word is used in two ways. In the narrow sense, an acronym is a sequence of letters when pronounced together as a single word, like NASA, NATO, or laser. In the broad sense, the term includes this kind of sequence when pronounced letter by letter. Sources that differentiate the two often call the former acronyms and the latter initialisms or alphabetisms. However, acronym is popularly used to refer to either concept, and both senses of the term are attributed as far back as the 1940s. Dictionary and style-guide editors dispute whether the term acronym can be legitimately applied to abbreviations which are not pronounced as words, and there is no general agreement on standard acronym spacing, casing, and punctuation.
The phrase that the acronym stands for is called its. The of an acronym includes both its expansion and the meaning of its expansion.
Etymology
The word acronym is formed from the Greek roots akro-, meaning 'height, summit, or tip', and -nym, 'name'. This neoclassical compound appears to have originated in German, with attestations for the German form Akronym appearing as early as 1921. Citations in English date to a 1940 translation of a novel by the German writer Lion Feuchtwanger.Dispute over the scope of ''acronym''
English lexicography and style guides differ on whether acronym should apply only to abbreviations pronounced as ordinary words or also to letter-by-letter initialisms. Some authorities accept or record the broader sense; others restrict acronym to word-pronounced forms and prefer initialism for the rest. Among sources that acknowledge the broader sense, attitudes range from neutral recording to prescriptive criticism.Dictionaries
Some mainstream English dictionaries from across the English-speaking world affirm a sense of acronym that does not require its pronunciation as a word. American English dictionaries such as Merriam-Webster, Dictionary.com's Random House Webster's Unabridged Dictionary and the American Heritage Dictionary as well as the British Oxford English Dictionary and the Australian Macquarie Dictionary all include a sense in their entries for acronym equating it with initialism, although The American Heritage Dictionary criticizes it with the label "usage problem". However, many English language dictionaries, such as the Collins COBUILD Advanced Dictionary, Cambridge Advanced Learner's Dictionary, Macmillan Dictionary, Longman Dictionary of Contemporary English, New Oxford American Dictionary, Webster's New World Dictionary, and Lexico from Oxford University Press do not acknowledge such a sense.Style and usage guides
English language usage and style guides which have entries for acronym generally criticize the usage that refers to forms that are not pronounceable words. Fowler's Dictionary of Modern English Usage says that acronym "denotes abbreviations formed from initial letters of other words and pronounced as a single word, such as NATO " but adds later "In everyday use, acronym is often applied to abbreviations that are technically initialisms, since they are pronounced as separate letters." The Chicago Manual of Style acknowledges the complexity but still defines the terms as mutually exclusive. Other guides outright deny any legitimacy to the usage: Bryson's Dictionary of Troublesome Words says "Abbreviations that are not pronounced as words are not acronyms; they are just abbreviations." Garner's Modern American Usage says "An acronym is made from the first letters or parts of a compound term. It's read or spoken as a single word, not letter by letter." The New York Times Manual of Style and Usage says "Unless pronounced as a word, an abbreviation is not an acronym."In contrast, some style guides do support it, whether explicitly or implicitly. The 1994 edition of Merriam-Webster's Dictionary of English Usage defends the usage on the basis of a claim that dictionaries do not make a distinction. The BuzzFeed style guide describes CBS and PBS as "acronyms ending in S".
Historical development and antedating
Most of the dictionary entries and style guide recommendations regarding the term acronym in the twentieth century did not explicitly acknowledge or support the expansive sense. The Merriam–Webster's Dictionary of English Usage from 1994 is one of the earliest publications to advocate for the expansive sense, and all the major dictionary editions that include a sense of acronym equating it with initialism were first published in the twenty-first century. The trend among dictionary editors appears to be towards including a sense defining acronym as initialism: the Merriam-Webster's Collegiate Dictionary added such a sense in its 11th edition in 2003, and both the Oxford English Dictionary and The American Heritage Dictionary added such senses in their 2011 editions. The 1989 edition of the Oxford English Dictionary only included the exclusive sense for acronym and its earliest citation was from 1943. In early December 2010, Duke University researcher Stephen Goranson published a citation for acronym to the American Dialect Society e-mail discussion list which refers to PGN being pronounced "pee-gee-enn", antedating English language usage of the word to 1940. Linguist Ben Zimmer then mentioned this citation in his December 16, 2010 "On Language" column about acronyms in The New York Times Magazine. By 2011, the publication of the 3rd edition of the Oxford English Dictionary added the expansive sense to its entry for acronym and included the 1940 citation. As the Oxford English Dictionary structures the senses in order of chronological development, it now gives the "initialism" sense first.Examples

Historical and current use
Ancient examples of acronymy include the following:
- Acronyms were used in Rome before the Christian era. For example, the official name for the Roman Empire, and the Republic before it, was abbreviated as SPQR. Inscriptions dating from antiquity, both on stone and on coins, use many abbreviations and acronyms to save space and work. For example, Roman first names, of which there was only a small set, were almost always abbreviated. Common terms were abbreviated too, such as writing just "F" for filius, meaning "son", a very common part of memorial inscriptions mentioning people. Grammatical markers were abbreviated or left out entirely if they could be inferred from the rest of the text.
- So-called nomina sacra were used in many Greek biblical manuscripts. The common words God, Jesus, Christ, and some others, would be abbreviated by their first and last letters, marked with an overline. This was just one of many kinds of conventional scribal abbreviation, used to reduce the time-consuming workload of the scribe and save on valuable writing materials. The same convention is still commonly used in the inscriptions on religious icons and the stamps used to mark the eucharistic bread in Eastern Churches.
- The early Christians in Rome, most of whom were Greek rather than Latin speakers, used the image of a fish as a symbol for Jesus in part because of an acronym : 'fish' in Greek is , which was construed to stand for . This interpretation dates from the second and third centuries and is preserved in the catacombs of Rome. Another ancient acronym for Jesus is the inscription INRI over the crucifix, for the Latin Iesus Nazarenus Rex Iudaeorum.
- Hebrew has a millennia-long history of acronyms pronounced as words. Along with theophoric parallels to the Greek described above, Talmudic sages as early as Rabbi Yehuda shorten the ten plagues to דצ"ך עד"ש באח"ב, the order of blessings to יקנה"ז, etc., for the sake of mnemonic. The rishonic period saw Hebrew acronymy expand to a lexicon of many hundreds, including every type of word and extending to proper nouns: almost all Medieval rabbis are known by acronyms like Rashi and Rambam.
Another field for the adoption of acronyms was modern warfare, with its many highly technical terms. While there is no recorded use of military acronyms dating from the American Civil War, they became somewhat common in World War I, and by World War II they were widespread even in the slang of soldiers, who referred to themselves as G.I.s.
The widespread, frequent use of acronyms across the whole range of linguistic registers is relatively new in most languages, becoming increasingly evident since the mid-twentieth century. As literacy spread and technology produced a constant stream of new and complex terms, abbreviations became increasingly convenient. The Oxford English Dictionary records the first printed use of the word initialism as occurring in 1899, but it did not come into general use until 1965, well after acronym had become common.
In English, acronyms may be a twentieth-century phenomenon. Linguist David Wilton in Word Myths: Debunking Linguistic Urban Legends claims that "forming words from acronyms is a distinctly twentieth- century phenomenon. There is only one known pre-twentieth-century word with an acronymic origin and it was in vogue for only a short time in 1886. The word is colinderies or colinda, an acronym for the Colonial and Indian Exposition held in London in that year." However, although acronymic words seem not to have been before the twentieth century, the is treated as effortlessly understood in an Edgar Allan Poe story of the 1830s, "How to Write a Blackwood Article", which includes the contrived acronym "P.R.E.T.T.Y.B.L.U.E.B.A.T.C.H."
