Usually, but not always, it consists of a letter or group of letters taken from the word or phrase. For example, the word "abbreviation" can itself be represented by the abbreviation "abbr." or "abbrev."Contents[hide]∙ 1 History∙ 2 Types of abbreviationo 2.1 Syllabic abbreviation▪ 2.1.1 Use in various languages▪ 2.1.2 Syllabic abbreviations in names of organizations ∙ 3 Style conventions in Englisho 3.1 Lowercase letterso 3.2 Periods (full stops) and spaceso 3.3 Plural formso 3.4 Conventions followed by publications and newspapers▪ 3.4.1 United States▪ 3.4.2 United Kingdom▪ 3.4.3 Miscellaneous and general rules∙ 4 Measurement∙ 5 See also∙ 6 References7 External links[edit] HistoryAbbreviation has been used as long as phonetic script existed, in some senses actually being more common in early literacy, where spelling out a whole word was often avoided, initial letters commonly being used to represent words in specific application. By classical Greece and Rome, the reduction of words to single letters was still normal, but no longer the default.An increase in literacy has, historically, sometimes spawned a trend toward abbreviation. The standardization of English in the 15th through 17th centuries included such a growth in the use of abbreviation[1]. At first, abbreviations were sometimes represented with various suspension signs, not only periods. For example, specific phoneme sets like "er" were dropped from words and replaced with ɔ, like "mastɔ" instead of "master" or exacɔbate instead of "exacerbate". While this seems trivial, it was symptomatic of an attempt by people manually reproducing academic texts to reduce their copy time. An example from the Oxford university Register, 1503:Mastɔ subwardenɔ y ɔmēde me to you. And wherɔ y wrot to you the last wyke that y trouyde itt good to differrɔ thelectionɔ ovɔto quīdenaɔ tinitatis y have be thougħt me synɔ that itt woll be thenɔ a bowte mydsomɔ.In the 1830s in the United States, starting with Boston, abbreviation became a fad. For example, during the growth of philological linguistic theory in academic Britain, abbreviating became very trendy. The use of abbreviation for the names of "Father of modern etymology" J. R. R. Tolkien and his friend C. S. Lewis, and other members of Oxford literary group known as the Inklings, are sometimes cited as symptomatic of this. Likewise, a century earlier in Boston, a fad of abbreviation started that swept the United States, with the globally popular term OK generally credited as a remnant of its influence.[2][3]After World War II, the British greatly reduced their use of the full stop and other punctuations after abbreviations in at least semi-formal writing, while the Americans more readily kept its use until more recently, and still maintain it more than Britons. The classic example, considered by their American counterparts quite curious, was the maintenance of the internal comma in a British organization of secret agents called the"Special Operations, Executive" — "S.O.,E" — which is not found in histories written after about 1960.But before that, many Britons were more scrupulous at maintaining the French form. In French, the period only follows an abbreviation if the last letter in the abbreviation is not the last letter of its antecedent: "M." is the abbreviation for "monsieur" while "Mme" is that for "madame". Like many other cross-channel linguistic acquisitions, many Britons readily took this up and followed this rule themselves, while the Americans took a simpler rule and applied it rigorously.Over the years, however, the lack of convention in some style guides has made it difficult to determine which two-word abbreviations should be abbreviated with periods and which should not. The U.S. media tend to abbreviate two-word abbreviations like United States (U.S.), but not personal computer (PC) or television (TV). Many British publications have gradually done away with the use of periods in abbreviations completely.Minimization of punctuation in typewritten matter became economically desirable in the 1960s and 1970s for the many users of carbon-film ribbons, since a period or comma consumed the same length of non-reusable expensive ribbon as did a capital letter.[edit] Types of abbreviationApart from the common form of word-contraction, there are other types of abbreviation. These include acronym and initialism (includingthree-letter acronyms), apocope, clipping, elision, syncope, syllabic abbreviation, and portmanteau words.[edit] Syllabic abbreviationSee also: Clipping (morphology)A syllabic abbreviation (SA) is an abbreviation formed from (usually) initial syllables of several words, such as Interpol for Inter national pol ice, but should be distinguished from portmanteau words. They are usually written in lower case, sometimes starting with a capital letter, and are always pronounced as words rather than letter by letter.[edit] Use in various languagesSyllabic abbreviations are not widely used in English or French, but are common in certain languages, like German and Russian.They prevailed in Germany under the Nazis and in the Soviet Union for naming the plethora of new bureaucratic organizations. For example, Gestapo stands for Ge heime Sta ats-Po lizei, or "secret state police". This has given syllabic abbreviations a negative connotation, even though they were used in Germany before the Nazis, such as Schupo for Schutzpolizist. Even now Germans call part of their police Kripo for Kriminalpolizei. Syllabic abbreviations were also typical of German language used in the German Democratic Republic, for example, Stasi for Staatssicherheit ("state security", the secret police and secret service) or Vopo for Volkspolizist ("people's policeman").Some syllabic abbreviations from Russian that are familiar to English speakers include samizdat and kolkhoz. The English names for the Soviet "Comintern" (Com munist Intern ational) and "Milrevcom" (Mil itaryRev olution Com mittee) are further examples.Orwell's novel 1984 uses fictional syllabic abbreviations like "Ingsoc" (Eng lish Soc ialism) to evoke the use of language under the Nazi and Soviet regimes.East Asian languages whose writing uses Chinese-originated ideograms instead of an alphabet form abbreviations similarly by using key characters from a term or phrase. For example, in Japanese the term for the United Nations, kokusai rengō (国際連合) is often abbreviated to kokuren(国連). Such abbreviations are called ryakugo(略語) in Japanese. SAs are frequently used for names of universities: for instance, Beida(北大, Běidà) for Peking University (Beijing), Yondae (연대) for the Yonsei University, Seouldae (서울대) for the Seoul National University and Tōdai (東大) for the University of Tokyo.[edit] Syllabic abbreviations in names of organizationsSyllabic abbreviations are preferred by the U.S. Navy as it increases readability amidst the large number of initialisms that would otherwise have to fit into the same acronyms. Hence DESRON 6 is used (in the full capital form) to mean "Destroyer Squadron 6," and COMNAVAIRLANT means "Commander, Naval Air Forces, Atlantic".[edit] Style conventions in EnglishIn modern English there are several conventions for abbreviations and the choice may be confusing. The only rule universally accepted is that one should be consistent, and to make this easier, publishers express their preferences in a style guide. Questions which arise include those in the following subsections.[edit] Lowercase lettersIf the original word was capitalized, then the first letter of its abbreviation should retain the capital, for example Lev. for Leviticus. When abbreviating words spelled with lower case letters, there is no need for capitalization, therefore no need for a consistent rule.[edit] Periods (full stops) and spacesA period (full stop) is sometimes written after an abbreviated word, but there is much disagreement and many exceptions.There is never a period (full stop) between letters of the same word. For example, Tiberius is abbreviated as Tb. and not as T.b..In formal British English, according to Hart's Rules, it is more common to write abbreviations with full stops if the word has been cut at the point of abbreviation but not otherwise: for example:∙"Doctor" becomes "Dr" (for "D–r")∙"Professor" becomes "Prof." (for "Prof...")∙"The Reverend" becomes "Revd" (for "Rev–d")∙"The Right Honourable" becomes "Rt Hon." (for "R–t Hon...")In American English, the period is usually added if the abbreviation might otherwise be interpreted as a word, but some American writers do not use a period here. Sometimes, periods are used for certain initialisms but not others; a notable instance in American English is to write United States, European Union, and United Nations as U.S., EU, and UN respectively.A third standard removes the full stops from all abbreviations (both "Saint" and "Street" become "St"). The U.S. Manual on Uniform Traffic Control Devices advises that periods should not be used with abbreviations on road signs, except for cardinal directions as part of a destination name. (For example, "Northwest Blvd", "W. Jefferson", and "PED XING"all follow this recommendation.)Acronyms that were originally capitalized (with or without periods) but have since entered the vocabulary as generic words are no longer abbreviated with capital letters nor with any periods. Examples are sonar, radar, lidar, laser, and scuba.Spaces are generally not used between single letter abbreviations of words in the same phrase, so one almost never encounters "U. S.".When an abbreviation appears at the end of a sentence, use only one period: The capital of the United States is Washington, D.C.[edit] Plural formsTo form the plural of an abbreviation, a number, or a capital letter used as a noun, simply add a lowercase s to the end.∙ A group of MPs∙The roaring '20s∙Mind your Ps and QsTo form the plural of an abbreviation with periods, a lowercase letter used as a noun, and abbreviations or capital letters that would be ambiguous or confusing if the 's' alone were added, use an apostrophe and an s.∙ A group of Ph.D.'s∙The x's of the equation∙Sending SOS'sIn Latin, and continuing to the derivative forms in European languages as well as English, single-letter abbreviations had the plural being a doubling of the letter, e.g. for footnotes.∙ d. didot — dd. didots (typography)∙h. hand — hh. hands (horse height)∙l. line — ll. lines∙p. page — pp. pages∙P. pope — PP. popes∙v. volume — vv. volumes[edit] Conventions followed by publications and newspapers [edit] United StatesPublications based in the U.S. tend to follow the style guides of the Chicago Manual of Style and the Associated Press.[verification needed] The U.S. Government follows a style guide published by the U.S. Government Printing Office.However, there is some inconsistency in abbreviation styles, as they are not rigorously defined by style guides. Some two-word abbreviations, like "United Nations", are abbreviated with uppercase letters and periods, and others, like "personal computer" (PC) and "compact disc" (CD), are not; rather, they are typically abbreviated without periods and in uppercase letters. A third variation is to use lowercase letters with periods; this is used by Time Magazine in abbreviating "public relations" (p.r.). Moreover, even three-word abbreviations (most U.S. publications use uppercase abbreviations without periods) are sometimes not consistently abbreviated, even within the same article.The New York Times is unique in having a consistent style by always abbreviating with periods: P.C., I.B.M., P.R. This is in contrast with the trend of British publications to omit periods for convenience.[edit] United KingdomMany British publications follow some of these guidelines in abbreviation:∙For the sake of convenience, many British publications, including the BBC and The Guardian, have completely done away with the use of full stops or periods in all abbreviations.These include:∙o Social titles, like Ms or Mr (though these would usually not have had full stops — see above) Capt, Prof, etc.;o Two-letter abbreviations for countries ("US", not "U.S.");o Abbreviations beyond three letters (full caps for all except initialisms);o Words seldom abbreviated with lower case letters ("PR", instead of "p.r.", or "pr")o Names ("FW de Klerk", "GB Whiteley", "Park JS"). A notable exception is the newspaper The Economist which writes "Mr F.W. de Klerk".o Scientific units (see Measurement below).∙Acronyms are often referred to with only the first letter of the abbreviation capitalised. For instance, the North Atlantic TreatyOrganisation can be abbreviated as "Nato" or "NATO", and Severe Acute Respiratory Syndrome as "Sars" or "SARS" (compare with"laser" which has made the full transition to an English word and is rarely capitalised at all).∙Initialisms are always written in capitals; for example the "British Broadcasting Corporation"is abbreviated to "BBC", never "Bbc". An initialism is similar to acronym but is not pronounced as a word.∙When abbreviating scientific units, no space is added between the number and unit (100mph, 100m, 10cm, 10°C). (This is contrary to the SI standard, see below.)[edit] Miscellaneous and general rules∙Plurals are often formed by doubling the last letter of the abbreviation. Most of these deal with writing and publishing:MS=manuscript, MSS=manuscripts; l=line, ll=lines; p=page,pp=pages; s=section, ss=sections; op.=opus, opp.=opera. This form, derived from Latin is used in Europe in many places: dd=didots. "The following (lines or pages)" is denoted by "ff". One example that does not concern printing is hh=hands.∙ A doubled letter also appears in abbreviations of some Welsh names, as in Welsh the double "l" is a separate sound: "Ll. George" for (British prime minister) Lloyd George.∙Some titles, such as "Reverend" and "Honourable", are spelt out when preceded by "the", rather than as "Rev." or "Hon." respectively.This is true for most British publications, and some in the United States.∙It is usually advised to spell out the abbreviation where it is new or unfamiliar to the reader (UNESCO in a magazine about music,because it refers to the United Nations Educational, Scientific and Cultural Organization, whose work does not concern the music).∙It is considered acceptable to start off a sentence with an abbreviation, however it is then advised to "ignore" theabbreviation and start the sentence as if it had begun with noabbreviation, but only if it is not the name of a person, place, or thing. For example, "BTW There is a new office manager." would be acceptable, though even without capping the "T", this instance is still accepted.[edit] MeasurementThe International System of Units(SI) defines a set of base units, from which other "derived" units may be obtained. The abbreviations, or moreaccurately "symbols" (using Roman letters, or Greek in the case of ohm) for these units are also clearly defined together with a set of prefixes for which there are also abbreviations or symbols. There should never be a period after or inside a unit; both '10 k.m.' and '10 k.m' are wrong — the only correct form is '10 km' (only followed with a period when at the end of a sentence).A period "within" a compound unit denotes multiplication of the base units on each side of it. Ideally, this period should be raised to the centre of the line, but often it is not. For instance, '5 ms' means 5 millisecond(s), whereas '5 m.s' means 5 metre·second(s). The "m.s" here is a compound unit formed from the product of two fundamental SI units — metre and second.There should always be a (non-breaking) space between the number and the unit — '25 km' is correct, and '25km' is incorrect. In Section 5.3.3. of The International System of Units (SI), the International Bureau of Weights and Measures (BIPM) states "The numerical value always precedes the unit, and a space is always used to separate the unit from the number. … The only exceptions to this rule are for the unit symbols for degree, minute, and second for plane angle."[4]The case of letters(uppercase or lowercase) has meaning in the SI system, and should never be changed in a misguided attempt to follow an abbreviation style. For example, "10 S" denotes 10 siemens (a unit of conductance), while "10 s" denotes 10 seconds. Any unit named after a person is denoted by a symbol with an upper case first letter (S, Pa, A, V, N, Wb, W), but spelt out in full in lower case, (siemens, pascal, ampere, volt, newton, weber and watt). By contrast g, l, m, s, cd, ha represent gramme, litre, metre, second, candela and hectare respectively. The one slight exception to this rule is that the symbol for litre is allowed to be L to help avoid confusion with an upper case i or a one in some typefaces — compare l, I, and 1.Likewise, the abbreviations of the prefixes denoting powers of ten are case-sensitive: m (milli) represents a thousandth, but M (mega) represents a million, so by inadvertent changes of case one may introduce (in this example) an error of a factor of 1 000 000 000. When a unit is written in full, the whole unit is written in lowercase, including the prefix: millivolt for mV, nanometre for nm, gigacandela for Gcd.The above rules, if followed, ensure that the SI system is always unambiguous, so for instance mK denotes millikelvin, MK denotes megakelvin, K.m denotes kelvin.metre, and km denotes kilometre. Formssuch as k.m and Km are ill-formed and technically meaningless in the SI system, although the intended meaning might be inferred from the context.[edit] See also。
