Neoclassical compounds are compound words composed from combining forms (which act as affixes or stems ) derived from classical languages ( classical Latin or ancient Greek ) roots . Neo-Latin comprises many such words and is a substantial component of the technical and scientific lexicon of English and other languages, via international scientific vocabulary (ISV). For example, Greek bio- combines with -graphy to form biography ("life" + "writing/recording").
90-706: EXACTO , an acronym of "Extreme Accuracy Tasked Ordnance", is a sniper rifle firing smart bullets being developed for DARPA (Defense Advanced Research Projects Agency) by Lockheed Martin and Teledyne Scientific & Imaging in November 2008. The new .50 BMG gun and improved scope could employ " fire-and-forget " technologies including "fin-stabilized projectiles, spin-stabilized projectiles, internal and/or external aero-actuation control methods, projectile guidance technologies, tamper proofing, small stable power supplies, and advanced sighting, optical resolution and clarity technologies". Its estimated availability at
180-516: A Fernsprecher , public telephones will be labelled with the internationally recognized Telefon . These words are compounds formed from Latin and Ancient Greek root words. Ancient Greek words are almost invariably romanized (see transliteration of Ancient Greek into English ). In English: Thus, for example, Ancient Greek σφιγξ becomes English (and Latin) sphinx . Exceptions to these romanizing rules occur, such as leukemia (leukaemia) ; compare leukocyte , also leucocyte . In Latin, and in
270-599: A constructed language based on English which others have called "Ander-Saxon"; this attempted to create a pure English vocabulary for nuclear physics . For more information, see Linguistic purism in English . Many such words, such as thermometer , dinosaur , rhinoceros , and rhododendron , are thoroughly incorporated into the English lexicon and are the ordinary words for their referents. Some are prone to colloquial shortening; rhinoceros often becomes rhino . The binomial nomenclature of taxonomy and biology
360-428: A numeronym . For example, "i18n" abbreviates " internationalization ", a computer-science term for adapting software for worldwide use; the "18" represents the 18 letters that come between the first and the last in "internationalization". Similarly, "localization" can be abbreviated "l10n"; " multilingualization " "m17n"; and " accessibility " "a11y". In addition to the use of a specific number replacing that many letters,
450-645: A single word ("television" or "transvestite", for instance), and is in general spelled without punctuation (except in the plural). Although "PS" stands for the single English word " postscript " or the Latin postscriptum , it is often spelled with periods ("P.S.") as if parsed as Latin post scriptum instead. The slash ('/', or solidus ) is sometimes used to separate the letters in an acronym, as in "N/A" ("not applicable, not available") and "c/o" ("care of"). Inconveniently long words used frequently in related contexts can be represented according to their letter count as
540-452: A 1940 translation of a novel by the German writer Lion Feuchtwanger . It is an unsettled question in English lexicography and style guides whether it is legitimate to use the word acronym to describe forms that use initials but are not pronounced as a word. While there is plenty of evidence that acronym is used widely in this way, some sources do not acknowledge this usage, reserving
630-433: A classical compound has been created and borrowed , it typically becomes the foundation of a whole series of related words: e.g. astrology , astrological, astrologer/astrologist/astrologian, astrologism . Mainstream medical and ISV pronunciation in English is not the same as Classical Latin pronunciation. Like Ecclesiastical Latin , it has a regularity of its own, and individual sounds can be mapped or compared. Although
720-625: A different meaning. Medical literature has been struggling to control the proliferation of acronyms, including efforts by the American Academy of Dermatology. Acronyms are often taught as mnemonic devices: for example the colors of the rainbow are ROY G. BIV (red, orange, yellow, green, blue, indigo, violet). They are also used as mental checklists: in aviation GUMPS stands for gas-undercarriage-mixture-propeller-seat belts. Other mnemonic acronyms include CAN SLIM in finance, PAVPANIC in English grammar, and PEMDAS in mathematics. It
810-670: A form stands alone as a present-day word, it is usually a telescopic abbreviation: bio biography, chemo chemotherapy, hydro hydroelectricity, metro metropolitan. Some telescoped forms are shorter than the original neoclassical combining form: gynie is shorter than gyneco- and stands for both gynecology and gynecologist ; anthro is shorter than anthropo- and stands for anthropology . Suffixes include: -ectomy cutting out, -graphy writing, description, -kinesis motion, -logy study, -mancy divination, -onym name, -phagy eating, -phony sound, -therapy healing, -tomy cutting. They are generally listed in dictionaries without
900-481: A hyphen ( auto-analysis , bioenergy , hydroelectricity , not * autanalysis , * bienergy , * hydrelectricity ). Its presence helps to distinguish neoclassical compounds like biography and agriculture from vernacular compounds like teapot and blackbird . Generally, English has acquired its neoclassical compounds in three ways: through French from Latin and Greek, directly from Latin and Greek, and by coinage in English on Greek and Latin patterns. An exception
990-420: A life', neurology as 'the study of the nervous system'. Many classical combining forms are designed to take initial or final position: autobiography has the two initial or preposed forms auto- and bio- , and one postposed form -graphy . Although most occupy one position or the other, some can occupy both: -graph- as in graphology and monograph ; -phil- as in philology and Anglophile . Occasionally,

#17327943395951080-781: A medial decimal point . Particularly in British and Commonwealth English , all such punctuation marking acronyms and other capitalized abbreviations is now uncommon and considered either unnecessary or incorrect. The presence of all-capital letters is now thought sufficient to indicate the nature of the UK , the EU , and the UN . Forms such as the U.S.A. for "the United States of America " are now considered to indicate American or North American English . Even within those dialects, such punctuation
1170-456: A noun (life), -graphy as a verbal noun (writing). This is why some reference works also call them stems . They are also often loosely called roots because they are ancient and have a basic role in word formation, but functionally and often structurally they are distinct from roots proper: the -graph in autograph is both a root and a classical combining form, while the -graphy in cryptography consists of root -graph- and suffix -y , and
1260-416: A noun-forming suffix that means "process of". In Greek and Latin grammar, combining bases usually require a thematic or stem-forming vowel. In biography , from Greek, the thematic is - o -; in agriculture , from Latin, it is -i- . In English morphology, this vowel can be considered as an interfix : in biology, the interfix -o- ; in miniskirt , the interfix -i- . It is usually regarded as attached to
1350-407: A period when the letters are pronounced individually, as in " K.G.B. ", but not when pronounced as a word, as in " NATO ". The logic of this style is that the pronunciation is reflected graphically by the punctuation scheme. When a multiple-letter abbreviation is formed from a single word, periods are in general not used, although they may be common in informal usage. "TV", for example, may stand for
1440-411: A similar role to Latin and Greek has been played by Chinese, with non-Chinese languages both borrowing a significant number of words from Chinese and using morphemes borrowed from Chinese to coin new words, particularly in formal or technical language. See Sino-Japanese vocabulary , Sino-Korean vocabulary , and Sino-Vietnamese vocabulary for discussion. The coinage of new native terms on Chinese roots
1530-436: A single word, such as NATO (as distinct from B-B-C )" 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 ("Furthermore, an acronym and initialism are occasionally combined (JPEG), and the line between initialism and acronym is not always clear") but still defines
1620-572: A smattering of the language in which it appears. Not all European languages have been equally receptive to neoclassical technical compounds. German and Russian , for instance, have historically attempted to create their own technical vocabularies from native elements. Usually, these creations are German and Russian calques on the international vocabulary, such as Wasserstoff and "водород" ( vodoród ) for hydrogen . Like any exercise in language prescription , this endeavour has been only partially successful, so while official German may still speak of
1710-477: A system-level live-fire test. The EXACTO program completed another round of live-fire tests in February 2015. In the tests, an experienced shooter used the guided rounds to track and hit a moving target several times. Video showed the bullets maneuvering in-flight to achieve hits. Additionally, an inexperienced shooter used the system and was still able to hit the moving target. In mid-2016, Russia revealed it
1800-515: A twentieth-century phenomenon. Linguist David Wilton in Word Myths: Debunking Linguistic Urban Legends claims that "forming words from acronyms is a distinctly twentieth- (and now twenty-first-) century phenomenon. There is only one known pre-twentieth-century [English] 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
1890-471: 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". Acronymy, like retronymy , is a linguistic process that has existed throughout history but for which there

#17327943395951980-677: 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
2070-479: Is schizophrenia , which came into English through German, and is therefore pronounced 'skitso', not 'skyzo'. Most dictionaries follow the Oxford English Dictionary in using combining form ( comb. form ) to label such classical elements. In appendices to dictionaries and grammar books, classical combining forms are often loosely referred to as roots or affixes: 'a logo …, properly speaking,
2160-572: Is a subset with a narrower definition: an initialism pronounced as a word rather than as a sequence of letters. In this sense, NASA / ˈ n æ s ə / is an acronym but USA / j uː ɛ s ˈ eɪ / is not. The broader sense of acronym , ignoring pronunciation, is its original meaning and in common use. Dictionary and style-guide editors dispute whether the term acronym can be legitimately applied to abbreviations which are not pronounced as words, and they do not agree on acronym spacing , casing , and punctuation . The phrase that
2250-622: Is a major source for these items of vocabulary; for many unfamiliar species that lack a common English name, the name of the genus becomes the English word for that life form. In the metric system , prefixes that indicate multipliers are typically Greek in origin, such as kilogram , while those that indicate divisors are Latin, as in millimeter : the base roots resemble Greek words, but in truth are neologisms . These metric and other suffixes are added to native English roots as well, resulting in creations such as gigabyte . Words of mixed Latin and Greek lineage, or words that combine elements of
2340-488: Is a question about how to pluralize acronyms. Often a writer will add an 's' following an apostrophe, as in "PC's". However, Kate L. Turabian 's A Manual for Writers of Research Papers, Theses, and Dissertations , writing about style in academic writings, allows for an apostrophe to form plural acronyms "only when an abbreviation contains internal periods or both capital and lowercase letters". Turabian would therefore prefer "DVDs" and "URLs" but "Ph.D.'s". The style guides of
2430-721: Is becoming increasingly uncommon. Some style guides , such as that of the BBC , no longer require punctuation to show ellipsis ; some even proscribe it. Larry Trask , American author of The Penguin Guide to Punctuation , states categorically that, in British English , "this tiresome and unnecessary practice is now obsolete." Nevertheless, some influential style guides , many of them American , still require periods in certain instances. For example, The New York Times Manual of Style and Usage recommends following each segment with
2520-411: Is common for grammatical contractions (e.g. don't , y'all , and ain't ) and for contractions marking unusual pronunciations (e.g. a'ight , cap'n , and fo'c'sle for "all right", "captain", and "forecastle"). By the early twentieth century, it was standard to use a full stop/period/point , especially in the cases of initialisms and acronyms. Previously, especially for Latin abbreviations , this

It also gives students a convenient review list to memorize the important acronyms introduced in a textbook chapter. Expansion at first use and abbreviation keys originated in the print era, but they are equally useful for electronic text . While acronyms provide convenience and succinctness for specialists, they often degenerate into confusing jargon . This may be intentional, to exclude readers without domain-specific knowledge. New acronyms may also confuse when they coincide with an already existing acronym having
2700-464: Is generally said as two letters, but IPsec for Internet Protocol Security is usually pronounced as / ˌ aɪ ˈ p iː s ɛ k / or / ˈ ɪ p s ɛ k / , along with variant capitalization like "IPSEC" and "Ipsec". Pronunciation may even vary within a single speaker's vocabulary, depending on narrow contexts. As an example, the database programming language SQL is usually said as three letters, but in reference to Microsoft's implementation
2790-582: Is most notable in Japanese, where it is referred to as wasei kango ( 和製漢語 , Japanese-made Chinese-words) . Many of these have been subsequently borrowed into Chinese, Korean, and Vietnamese, with the same (or corresponding) characters being pronounced differently according to language, just as happens in European languages – compare English biology and French biologie . For example, 自動車 (Japanese jidōsha, Korean jadongcha, Mandarin zìdòngchē )

2880-490: Is not a word at all but a prefix meaning word and short for logogram, a symbol, much as telly is short for television' (Montreal Gazette , 13 Apr. 1981). They are often referred to as affixes because some come first and some come last. But if they were affixes proper, a word like biography would have no base whatever. While affixes are grammatical (like prepositions), classical combining forms are lexical (like nouns, adjectives, and verbs): for example, bio- translates as
2970-459: Is not uncommon for acronyms to be cited in a kind of false etymology , called a folk etymology , for a word. Such etymologies persist in popular culture but have no factual basis in historical linguistics , and are examples of language-related urban legends . For example, " cop " is commonly cited as being derived, it is presumed, from "constable on patrol", and " posh " from " port outward, starboard home ". With some of these specious expansions,
3060-483: Is only a classical combining form. From the Renaissance until the mid-20th century, the concept of derivational purity has often regulated the use of classical compounds, with a philological goal of like with like (Greek with Greek, Latin with Latin) and a minimum of hybridization . For example, biography is Greek, agriculture Latin; but this ideal has seen only limited realization in practice, as for example
3150-684: Is secondary to compactness and vividness of expression. In recent years, the orthography of many word forms has changed, usually without affecting pronunciation and stress. The same spoken usage may be written micro-missile , micro missile , micromissile , reflecting the same uncertainty or flexibility as in businessman , business-man , business man . When used in such ways, classical compounds are often telescopic: Hydro substation Hydro-Electricity Board substation, Metro highways Metropolitan highways, porno cult pornography cult. The mix of late 20th century techno-commercial coinages includes three groups of post- and non-classical forms: In East Asia,
3240-621: Is to treat the unfamiliar cluster as containing one or more silent letters and suppress their pronunciation, more modern speakers tend to try and pronounce the unusual cluster. This adds to the irregularities of English spelling ; moreover, since many of these words are encountered in writing more often than they are heard spoken, it introduces uncertainty as to how to pronounce them when encountered. Neoclassical compounds frequently vary their stressed syllable when suffixes are added: á griculture , agric ú ltural. This also gives rise to uncertainty when these words are encountered in print. Once
3330-415: Is traditionally pronounced like the word sequel . In writing for a broad audience, the words of an acronym are typically written out in full at its first occurrence within a given text. Expansion At First Use (EAFU) benefits readers unfamiliar with the acronym. Another text aid is an abbreviation key which lists and expands all acronyms used, a reference for readers who skipped past the first use. (This
3420-516: The Colonial and Indian Exposition held in London in that year." However, although acronymic words seem not to have been employed in general vocabulary before the twentieth century (as Wilton points out), the concept of their formation is treated as effortlessly understood (and evidently not novel) in an Edgar Allan Poe story of the 1830s, " How to Write a Blackwood Article ", which includes
3510-623: The Modern Language Association and American Psychological Association prohibit apostrophes from being used to pluralize acronyms regardless of periods (so "compact discs" would be "CDs" or "C.D.s"), whereas The New York Times Manual of Style and Usage requires an apostrophe when pluralizing all abbreviations regardless of periods (preferring "PC's, TV's and VCR's"). Possessive plurals that also include apostrophes for mere pluralization and periods appear especially complex: for example, "the C.D.'s' labels" (the labels of

OK , a term of disputed origin, dates back at least to the early nineteenth century and is now used around the world. Acronyms are used most often to abbreviate names of organizations and long or frequently referenced terms. The armed forces and government agencies frequently employ acronyms; some well-known examples from
3690-480: The "belief" that the etymology is acronymic has clearly been tongue-in-cheek among many citers, as with "gentlemen only, ladies forbidden" for " golf ", although many other (more credulous ) people have uncritically taken it for fact. Taboo words in particular commonly have such false etymologies: " shit " from "ship/store high in transit" or "special high-intensity training" and " fuck " from "for unlawful carnal knowledge", or "fornication under consent/command of

3780-733: The 1540s, and androgyne , from the 1550s. The use of these technical terms predates the scientific method ; the several varieties of divination all take their names from neoclassical compounds, such as alectryomancy , divination by the pecking of chickens . Not all English writers have been friendly to the inflow of classical vocabulary. The Tudor period writer Sir John Cheke wrote: I am of this opinion that our own tung should be written cleane and pure, unmixt and unmangeled with borrowing of other tunges; wherein if we take not heed by tiim, ever borowing and never paying, she shall be fain to keep her house as bankrupt. and therefore rejected what he called " inkhorn terms ". Similar sentiments moved

Some prescriptivists disdain texting acronyms and abbreviations as decreasing clarity, or as failure to use "pure" or "proper" English. Others point out that languages have always continually changed , and argue that acronyms should be embraced as inevitable, or as innovation that adapts
3960-461: The 18 letters between the initial "i" and the final "n"). Authors of expository writing will sometimes capitalize or otherwise distinctively format the initials of the expansion for pedagogical emphasis (for example, writing: "the onset of Congestive Heart Failure (CHF)" or "the onset of c ongestive h eart f ailure (CHF)"). Capitalization like this, however, conflicts with the convention of English orthography, which generally reserves capitals in
4050-466: The British press may render it "Nato"), but uses lower case in " Unicef " (from "United Nations International Children's Emergency Fund") because it is more than four letters, and to style it in caps might look ungainly (flirting with the appearance of "shouting capitals"). While abbreviations typically exclude the initials of short function words (such as "and", "or", "of", or "to"), this is not always

Footage released showed

Inventors are encouraged to anticipate the formation of acronyms by making new terms "YABA-compatible" ("yet another bloody acronym"), meaning the term's acronym can be pronounced and is not an offensive word: "When choosing a new name, be sure it is 'YABA-compatible'." Acronym use has been further popularized by text messaging on mobile phones with short message service (SMS), and instant messenger (IM). To fit messages into
4410-560: The United States are among the " alphabet agencies " (jokingly referred to as " alphabet soup ") created under the New Deal by Franklin D. Roosevelt (himself known as "FDR"). Business and industry also coin acronyms prolifically. The rapid advance of science and technology also drives the usage, as new inventions and concepts with multiword names create a demand for shorter, more pronounceable names. One representative example, from
4500-411: The acronym may use normal case rules, e.g. it would appear generally in lower case, but with an initial capital when starting a sentence or when in a title. Once knowledge of the words underlying such an acronym has faded from common recall, the acronym may be termed an anacronym . Examples of anacronyms are the words " scuba ", " radar ", and " laser ". The word "an acro nym" should not be confused with
4590-545: The acronym stands for is called its expansion . The meaning of an acronym includes both its expansion and the meaning of its expansion. 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

#17327943395954680-590: 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 (acronyms such as "ANV" for " Army of Northern Virginia " post-date the war itself), 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
4770-506: The apostrophe should be reserved for the possessive ("the TV's antenna"). In some languages, the convention of doubling the letters in the acronym is used to indicate plural words: for example, the Spanish EE.UU. , for Estados Unidos ('United States'). This old convention is still sometimes followed for a limited number of English abbreviations, such as SS. for Saints , pp. for
4860-1163: The case. Sometimes function words are included to make a pronounceable acronym, such as CORE ( Congress of Racial Equality ). Sometimes the letters representing these words are written in lower case, such as in the cases of "TfL" (" Transport for London ") and LotR ( The Lord of the Rings ); this usually occurs when the acronym represents a multi-word proper noun. Numbers (both cardinal and ordinal ) in names are often represented by digits rather than initial letters, as in "4GL" (" fourth generation language ") or "G77" (" Group of 77 "). Large numbers may use metric prefixes , as with " Y2K " for "Year 2000". Exceptions using initials for numbers include " TLA " ("three-letter acronym/abbreviation") and "GoF" (" Gang of Four "). Abbreviations using numbers for other purposes include repetitions, such as " A2DP " ("Advanced Audio Distribution Profile"), " W3C " ("World Wide Web Consortium"), and T3 ( Trends, Tips & Tools for Everyday Living ); pronunciation, such as " B2B " ("business to business"); and numeronyms , such as "i18n" ("internationalization"; "18" represents
4950-450: The classical languages with English – so-called hybrid words – were formerly castigated as " barbarisms " by prescriptionist usage commentators; this disapproval has mostly abated. Indeed, in scientific nomenclature, even more exotic hybrids have appeared, such as for example the dinosaur Yangchuanosaurus . Personal names appear in some scientific names such as Fuchsia . Neoclassical compounds are sometimes used to lend grandeur or

In some instances, however, an apostrophe may increase clarity: for example, if the final letter of an abbreviation is "S", as in "SOS's" (although abbreviations ending with S can also take "-es", e.g. "SOSes"), or when pluralizing an abbreviation that has periods. A particularly rich source of options arises when the plural of an acronym would normally be indicated in a word other than
5130-564: The contrived acronym "P.R.E.T.T.Y.B.L.U.E.B.A.T.C.H." The use of Latin and Neo-Latin terms in vernaculars has been pan-European and pre-dates modern English. Some examples of acronyms in this class are: The earliest example of a word derived from an acronym listed by the OED is "abjud" (now " abjad "), formed from the original first four letters of the Arabic alphabet in the late eighteenth century. Some acrostics pre-date this, however, such as
5220-438: The dictionary entries and style guide recommendations regarding the term acronym through 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
5310-664: 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,
5400-763: The final word if spelled out in full. A classic example is "Member of Parliament", which in plural is "Members of Parliament". It is possible then to abbreviate this as "M's P", which was fairly common in mid-twentieth-century Australian news writing (or similar ), and used by former Australian Prime Minister Ben Chifley . This usage is less common than forms with "s" at the end, such as "MPs", and may appear dated or pedantic. In common usage, therefore, "weapons of mass destruction" becomes "WMDs", "prisoners of war" becomes "POWs", and "runs batted in" becomes "RBIs". Abbreviations that come from single, rather than multiple, words – such as "TV" ("television") – are usually pluralized without apostrophes ("two TVs"); most writers feel that
5490-464: The first letter of acronyms, reserving all-caps styling for initialisms, writing the pronounced acronyms "Nato" and "Aids" in mixed case, but the initialisms "USA" and "FBI" in all caps. For example, this is the style used in The Guardian , and BBC News typically edits to this style (though its official style guide, dating from 2003, still recommends all-caps ). The logic of this style is that

#17327943395955580-778: The impression of scientific rigour to humble pursuits: the study of cosmetology will not help anyone become an astronaut . Compounds along these models are also sometimes coined for humorous effect, such as odontopodology , the science of putting your foot into your mouth. These humorous coinages sometimes take on a life of their own, such as garbology , the study of garbage . Some neoclassical compounds form classical plurals , and are therefore irregular in English. Others do not, while some vacillate between classical and regular plurals. There are hundreds of neoclassical compounds in English and other European languages. As traditionally defined, combining forms cannot stand alone as free words, but there are many exceptions to this rule, and in
5670-433: The initial base ( bio- , mini- ) rather than the final base ( -graphy , -skirt ), but in forms where it is conventionally stressed , it is sometimes considered as part of the final base ( -ography , -ology ). If the final element begins with a vowel (for example, -archy as in monarchy ), the mediating vowel has traditionally been avoided (not * monoarchy ), but in recent coinages it is often kept, sometimes accompanied by
5760-405: The interfixed vowel, which appears however in such casual phrases as 'ologies and isms'. Some classical combining forms are variants of one base. Some are also free words, such as mania in dipsomania and phobia in claustrophobia . Some are composites of other elements, such as encephalo- brain, from en- in, -cephal- head; and -ectomy cutting out, from ec- out, -tom- cut, -y ,
5850-435: The king". In English, abbreviations have previously been marked by a wide variety of punctuation . Obsolete forms include using an overbar or colon to show the ellipsis of letters following the initial part. The forward slash is still common in many dialects for some fixed expressions—such as in w/ for "with" or A/C for " air conditioning "—while only infrequently being used to abbreviate new terms. The apostrophe
5940-500: 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. Most of

In this view, the modern practice is just the "proper" English of the current generation of speakers, much like the earlier abbreviation of corporation names on ticker tape or newspapers. Exact pronunciation of "word acronyms" (those pronounced as words rather than sounded out as individual letters) often vary by speaker population. These may be regional, occupational, or generational differences, or simply personal preference. For instance, there have been decades of online debate about how to pronounce GIF ( / ɡ ɪ f / or / dʒ ɪ f / ) and BIOS ( / ˈ b aɪ oʊ s / , / ˈ b aɪ oʊ z / , or / ˈ b aɪ ɒ s / ). Similarly, some letter-by-letter initialisms may become word acronyms over time, especially in combining forms: IP for Internet Protocol
6120-483: The late 20th century such forms are increasingly used independently: bio as a clipping of biography , telly as a respelt clipping of television . Most neoclassical combining forms translate readily into everyday language, especially nouns: bio- as 'life' -graphy as 'writing, description'. Because of this, the compounds of which they are part (usually classical or learned compounds ) can be more or less straightforwardly paraphrased: biography as 'writing about
6210-618: The later 20th century, many forms have cut loose from ancient moorings: crypto- as in preposed Crypto-Fascist and pseudo- as in pseudoradical ; postposed -meter in speedometer , clapometer . Processes of analogy have created coinages like petrodollar , psycho-warfare , microwave on such models as petrochemical , psychology , microscope . Such stunt usages as eco-doom , eco-fears , eco-freaks , common in journalism, often employ classical combining forms telescopically: eco- standing for ecology and ecological and not as used in economics . In such matters, precision of meaning
6300-703: The middle of sentences for proper nouns; when following the AMA Manual of Style , this would instead be rendered as "the onset of congestive heart failure (CHF)". Neoclassical compound Neoclassical compounds represent a significant source of Neo-Latin vocabulary. Moreover, since these words are composed from classical languages whose prestige is or was respected throughout the Western European culture, these words typically appear in many different languages. Their widespread use makes technical writing generally accessible to readers who may only have
6390-466: The more general "x" can be used to replace an unspecified number of letters. Examples include "Crxn" for "crystallization" and the series familiar to physicians for history , diagnosis , and treatment ("hx", "dx", "tx"). Terms relating to a command structure may also sometimes use this formatting, for example gold, silver, and bronze levels of command in UK policing being referred to as Gx, Sx, and Bx. There
6480-442: The nineteenth century author William Barnes to write "pure English," in which he avoided Greco-Latin words and found Anglo-Saxon equivalents for them: for Barnes, the newly invented art of the photograph became a sun-print . Unlike this one, some of Barnes's coinages caught on, such as foreword , Barnes's replacement for the preface of a book. Later, Poul Anderson wrote a jocular piece called Uncleftish Beholding in
6570-729: The plural of 'pages', or mss. for manuscripts . The most common capitalization scheme seen with acronyms is all-uppercase ( all caps ). Small caps are sometimes used to make the run of capital letters seem less jarring to the reader. For example, the style of some American publications, including the Atlantic Monthly and USA Today , is to use small caps for acronyms longer than three letters; thus "U.S." and " FDR " in normal caps, but " nato " in small caps. The acronyms " AD " and " BC " are often smallcapped as well, as in: "From 4004 bc to ad 525 ". Where an acronym has linguistically taken on an identity as regular word,
6660-483: The pronunciation is reflected graphically by the capitalization scheme. However, it conflicts with conventional English usage of first-letter upper-casing as a marker of proper names in many cases; e.g. AIDS stands for acquired immuno-deficiency syndrome which is not a proper name, while Aids is in the style of one. Some style manuals also base the letters' case on their number. The New York Times , for example, keeps "NATO" in all capitals (while several guides in
6750-685: 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. 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
6840-422: The rifle intentionally aiming off target so the bullets could correct their flight path. EXACTO technology is claimed to markedly extend the day and night-time range of current sniper systems. How the ammunition is designed to change direction in mid-air is classified. The second phase of the program was completed in summer 2014 with a number of improvements provided. The next phase included further refinements and
6930-560: The same base is repeated in one word: logology the study of words, phobophobia the fear of fear. Prefixes include: aero- air, crypto- hidden, demo- people, geo- earth, odonto- tooth, ornitho- bird, thalasso- sea. Many have both a traditional simple meaning and a modern telescopic meaning: in biology , bio- means 'life', but in bio-degradable it telescopes 'biologically'; although hypno- basically means 'sleep' ( hypnopaedia learning through sleep), it also stands for 'hypnosis' ( hypnotherapy cure through hypnosis). When
7020-470: The sides of railroad cars (e.g., "Richmond, Fredericksburg and Potomac Railroad" → "RF&P"); on the sides of barrels and crates; and on ticker tape and newspaper stock listings (e.g. American Telephone and Telegraph Company → AT&T). Some well-known commercial examples dating from the 1890s through 1920s include " Nabisco " ("National Biscuit Company"), " Esso " (from "S.O.", from " Standard Oil "), and " Sunoco " ("Sun Oil Company"). Another field for
7110-454: The target languages, the Greek vowels are given their neoclassical values rather than their contemporary values in demotic Greek . Ancient Greek words often contain consonant clusters which are foreign to the phonology of contemporary English and other languages that incorporate these words into their lexicon: diphthong ; pneumatology , phthisis . The traditional response in English
7200-476: The term acronym only for forms pronounced as a word, and using initialism or abbreviation for those that are not. Some sources acknowledge the usage, but vary in whether they criticize or forbid it, allow it without comment, or explicitly advocate it. Some mainstream English dictionaries from across the English-speaking world affirm a sense of acronym which does not require being pronounced as
7290-502: 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 (IBM, ABC, NFL) 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
7380-539: The time was 2015. The DARPA EXACTO program may face competition from Sandia National Laboratories for creating a guided sniper round. The DARPA EXACTO program uses different methods from Sandia's guided round. It relies on remote-guidance tied to the optics, which may be more reliable than Sandia's laser guidance method of painting the target with a laser for their projectile to follow, which can be detected, diffused, or blocked. EXACTO models on existing .50 BMG ammunition and rifles instead of needing new hardware, which
7470-493: 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
7560-536: 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 ( OED ) 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 pronounced as words may be
7650-456: The word television is a hybrid of Greek tele- and Latin -vision (probably so coined because the 'pure' form telescope had already been adopted for another purpose). Generally, classical compounds were a closed system from the 16th century to the earlier 20th century: the people who used them were classically educated , their teachers and exemplars generally took a purist's view on their use, contexts of use were mainly technical, and there
7740-425: The word " an achro nym ", which is a type of misnomer. Words derived from an acronym by affixing are typically expressed in mixed case, so the root acronym is clear. For example, "pre-WWII politics", "post-NATO world", " DNase ". In some cases a derived acronym may also be expressed in mixed case. For example, " messenger RNA " and " transfer RNA " become "mRNA" and "tRNA". Some publications choose to capitalize only
7830-519: Was developing a similar "smart bullet" designed to hit targets at a distance of up to 10 kilometres (6.2 mi). Acronym and initialism An acronym is a type of abbreviation consisting of a phrase whose only pronounced elements are the initial letters or initial sounds of words inside that phrase. Acronyms are often spelled with the initial letter of each word in all caps with no punctuation . For some, an initialism or alphabetism , connotes this general meaning, and an acronym
7920-511: Was done with a full space between every full word (e.g. A. D. , i. e. , and e. g. for " Anno Domini ", " id est ", and " exempli gratia "). This even included punctuation after both Roman and Arabic numerals to indicate their use in place of the full names of each number (e.g. LII. or 52. in place of "fifty-two" and "1/4." or "1./4." to indicate "one-fourth"). Both conventions have fallen out of common use in all dialects of English, except in places where an Arabic decimal includes
8010-449: Was little to no naming , conscious attention, or systematic analysis until relatively recent times. Like retronymy, it became much more common in the twentieth century than it had formerly been. Ancient examples of acronymy (before the term "acronym" was invented) include the following: During the mid- to late nineteenth century, acronyms became a trend among American and European businessmen: abbreviating corporation names, such as on
8100-879: Was relatively little seepage into the language at large. However, with the decline of classical education and the spread of technical and quasitechnical jargon in the media, a continuum has evolved, with at least five stages: In the older sciences, classical combining forms are generally used to form such strictly classical and usually Greek compounds as anthocyanin , astrobleme , chemotherapy , chronobiology , cytokinesis , glossolalia , lalophobia , narcolepsy , osteoporosis , Pliohippus , sympathomimetic . In technical, semitechnical, and quasitechnical usage at large, coiners of compounds increasingly treat Latin and Greek as one resource to produce such forms as accelerometer , aero-generator , bioprospector , communicology , electroconductive , futurology , mammography , micro-gravity , neoliberal , Scientology , servomechanism .
