It is used to indicate when information in a certain table cell is not provided, either because it does not apply to a particular case in question or because the answer is not available. Such a notation can be used on many different types of forms. The notation

Other such names which are used commonly in recent decades are GETOAR, composed from Gegeria + Tosks (representing the two main dialects of the Albanian language, Gegë and Toskë), and Arbanon —which
176-555: A plural of an initialization without an apostrophe can also be used for a number, or a letter. Examples: For units of measure, the same form is used for both singular and plural. Examples: When an abbreviation contains more than one period, Hart's Rules recommends putting the s after the final one. Examples: However, the same plurals may be rendered less formally as: According to Hart's Rules , an apostrophe may be used in rare cases where clarity calls for it, for example when letters or symbols are referred to as objects. However,
220-554: A single letter and was originally spelled with lower case letters then there is no need for capitalization. However, when abbreviating a phrase where only the first letter of each word is taken, then all letters should be capitalized, as in YTD for year-to-date , PCB for printed circuit board and FYI for for your information . However, see the following section regarding abbreviations that have become common vocabulary: these are no longer written with capital letters. A period (a.k.a. full stop)
264-508: A symbol such as "km" for " kilometre ". In the International System of Units (SI) manual the word "symbol" is used consistently to define the shorthand used to represent the various SI units of measure. The manual also defines the way in which units should be written , the principal rules being: A syllabic abbreviation is usually formed from the initial syllables of several words, such as Interpol = International + police . It
308-738: A word to a single letter was common in both Greek and Roman writing. In Roman inscriptions, "Words were commonly abbreviated by using the initial letter or letters of words, and most inscriptions have at least one abbreviation". However, "some could have more than one meaning, depending on their context. (For example, ⟨A⟩ can be an abbreviation for many words, such as ager , amicus , annus , as , Aulus , Aurelius , aurum , and avus .)" Many frequent abbreviations consisted of more than one letter: for example COS for consul and COSS for its nominative etc. plural consules . Abbreviations were frequently used in early English . Manuscripts of copies of
352-559: Is a syllabic abbreviation of Commonwealth and (Thomas) Edison . Sections of California are also often colloquially syllabically abbreviated, as in NorCal (Northern California), CenCal (Central California), and SoCal (Southern California). Additionally, in the context of Los Angeles, the syllabic abbreviation SoHo (Southern Hollywood) refers to the southern portion of the Hollywood neighborhood. Partially syllabic abbreviations are preferred by
396-528: Is a variant of the acronym. Syllabic abbreviations are usually written using lower case , sometimes starting with a capital letter , and are always pronounced as words rather than letter by letter. Syllabic abbreviations should be distinguished from portmanteaus , which combine two words without necessarily taking whole syllables from each. Syllabic abbreviations are not widely used in English. Some UK government agencies such as Ofcom (Office of Communications) and
440-755: Is an alternative way used to describe all Albanian lands. Syllabic abbreviations were and are common in German ; much like acronyms in English, they have a distinctly modern connotation, although contrary to popular belief, many date back to before 1933 , if not the end of the Great War . Kriminalpolizei , literally criminal police but idiomatically the Criminal Investigation Department of any German police force, begat KriPo (variously capitalised), and likewise Schutzpolizei ( protection police or uniform department ) begat SchuPo .

#1732869604485528-531: Is one of the grammatical cases of a noun or other part of speech, which generally marks the subject of a verb , or (in Latin and formal variants of English) a predicative nominal or adjective , as opposed to its object , or other verb arguments . Generally, the noun "that is doing something" is in the nominative, and the nominative is often the form listed in dictionaries. The English word nominative comes from Latin cāsus nominātīvus "case for naming", which
572-541: Is sometimes abbreviated abbr. , abbrv. , or abbrev. . But sometimes the trailing period is not used for such shortened forms. A contraction is an abbreviation formed by replacing letters with an apostrophe. Examples include I'm for I am and li'l for little . An initialism or acronym is an abbreviation consisting of the initial letter of a sequence of words without other punctuation. For example, FBI ( /ˌɛf.biːˈaɪ/ ), USA ( /ˌjuː.ɛsˈeɪ/ ), IBM ( /ˌaɪ.biːˈɛm/ ), BBC ( /ˌbiː.biːˈsiː/ ). When initialism
616-695: Is sometimes used to signify abbreviation, but opinion is divided as to when and if this convention is best practice. According to Hart's Rules , a word shortened by dropping letters from the end terminates with a period, whereas a word shorted by dropping letters from the middle does not. Fowler's Modern English Usage says a period is used for both of these shortened forms, but recommends against this practice: advising it only for end-shortened words and lower-case initialisms; not for middle-shortened words and upper-case initialisms. Some British style guides, such as for The Guardian and The Economist , disallow periods for all abbreviations. In American English ,
660-584: Is typically US . There are multiple ways to pluralize an abbreviation. Sometimes this accomplished by adding an apostrophe and an s ( 's ), as in "two PC's have broken screens". But, some find this confusing since the notation can indicate possessive case . And, this style is deprecated by many style guides. For instance, Kate Turabian , 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". For example, "DVDs" and "URLs" and "Ph.D.'s", while
704-522: Is used as the preferred term, acronym refers more specifically to when the abbreviation is pronounced as a word rather than as separate letters; examples include SWAT and NASA . Initialisms, contractions and crasis share some semantic and phonetic functions, and are connected by the term abbreviation in loose parlance. In early times, abbreviations may have been common due to the effort involved in writing (many inscriptions were carved in stone) or to provide secrecy via obfuscation . Reduction of
748-426: Is used for the subject of a transitive verb or a voluntary subject of an intransitive verb but not for an involuntary subject of an intransitive verb. Since such languages are a relatively new field of study, there is no standard name for this case. English is now often described as having a subjective case , instead of a nominative, to draw attention to the differences between the "standard" generic nominative and
792-551: The Modern Language Association explicitly says, "do not use an apostrophe to form the plural of an abbreviation". Also, the American Psychological Association specifically says, "without an apostrophe". However, the 1999 style guide for The New York Times states that the addition of an apostrophe is necessary when pluralizing all abbreviations, preferring "PC's, TV's and VCR's". Forming
836-679: The Old English poem Beowulf used many abbreviations, for example the Tironian et ( ⁊ ) or & for and , and y for since , so that "not much space is wasted". The standardisation of English in the 15th through 17th centuries included a growth in the use of such abbreviations. At first, abbreviations were sometimes represented with various suspension signs, not only periods. For example, sequences like ⟨er⟩ were replaced with ⟨ɔ⟩ , as in mastɔ for master and exacɔbate for exacerbate . While this may seem trivial, it
880-421: The accusative (comparable to the oblique or disjunctive in some other languages): I (accusative me ), we (accusative us ), he (accusative him ), she (accusative her ), they (accusative them ) and who (accusative whom ). A usage that is archaic in most current English dialects is the singular second-person pronoun thou (accusative thee ). A special case is the word you : originally, ye
924-456: The 1990s led to a marked rise in colloquial abbreviation. This was due largely to increasing popularity of textual communication services such as instant and text messaging. The original SMS supported message lengths of 160 characters at most (using the GSM 03.38 character set), for instance. This brevity gave rise to an informal abbreviation scheme sometimes called Textese , with which 10% or more of

#1732869604485968-652: The 20th century. The contractions in Newspeak are supposed to have a political function by virtue of their abbreviated structure itself: nice sounding and easily pronounceable, their purpose is to mask all ideological content from the speaker. A more recent syllabic abbreviation has emerged with the disease COVID-19 (Corona Virus Disease 2019) caused by the Severe acute respiratory syndrome coronavirus 2 (itself frequently abbreviated to SARS-CoV-2 , partly an initialism). In Albanian, syllabic acronyms are sometimes used for composing
1012-763: The US Navy, as they increase 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", while COMNAVAIRLANT would be "Commander, Naval Air Force (in the) Atlantic". Syllabic abbreviations are a prominent feature of Newspeak , the fictional language of George Orwell 's dystopian novel Nineteen Eighty-Four . The political contractions of Newspeak— Ingsoc (English Socialism), Minitrue (Ministry of Truth), Miniplenty ( Ministry of Plenty )—are described by Orwell as similar to real examples of German ( see below ) and Russian ( see below ) contractions in
1056-455: The apostrophe can be dispensed with if the items are set in italics or quotes: In 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 for note-taking. Most of these deal with writing and publishing. A few longer abbreviations use this as well. Publications based in the U.S. tend to follow
1100-570: The blank is not applicable, so that those processing the surveys would be able to see that the blank had not merely been overlooked. An Information Circular from the U.S. Department of the Interior , Bureau of Mines, from the same year specified that it used "NA" to indicate that information was "not available" and "NAp" to indicate that a category information was "Not applicable". In the early years of computer programming , computerized forms that required fields to be filled in could cause problems where
1144-414: The field was one for which no answer would be applicable to certain persons filling out the form. Before programmers became aware of a problem with a particular field, persons filling out that field might fill it in with a term such as this, which the program processing the form would misinterpret as an intent to provide the requested information. For example, if a form contained a field for a middle name, and

New York City has various neighborhoods named by syllabic abbreviation, such as Tribeca (Triangle below Canal Street) and SoHo (South of Houston Street). This usage has spread into other American cities, giving SoMa , San Francisco (South of Market) and LoDo, Denver (Lower Downtown), amongst others. Chicago -based electric service provider ComEd
1232-451: The globally popular term OK generally credited as a remnant of its influence. 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. This question is considered below. Widespread use of electronic communication through mobile phones and the Internet during
1276-451: The nominative case, but that is often not a complete specification of the reference form, as the number and the gender may need to be specified. Thus, the reference or least marked form of an adjective might be the nominative masculine singular. The parts of speech that are often declined and therefore may have a nominative case are nouns, adjectives, pronouns and (less frequently) numerals and participles. The nominative case often indicates
1320-487: The period is usually included regardless of whether or not it is a contraction, e.g. Dr. or Mrs. . In some cases, periods are optional, as in either US or U.S. for United States , EU or E.U. for European Union , and UN or U.N. for United Nations . There are some house styles, however—American ones included—that remove the periods from almost all abbreviations. For example: Acronyms that were originally capitalized (with or without periods) but have since entered
1364-437: The person filling out the form put "N/A", the computer might interpret this as "N/A" being the person's middle name; this in turn might result in the person receiving mail from the company that produced the form with "N/A" where a middle name would normally appear. Abbreviation An abbreviation may be a shortened form of a word with a trailing period. For example: etcetera is usually abbreviated etc. and abbreviation

With the National Socialist German Workers' Party gaining power came a frenzy of government reorganisation, and with it a series of entirely new syllabic abbreviations. The single national police force amalgamated from the Schutzpolizeien of the various states became the OrPo ( Ordnungspolizei , "order police");

The phrase politisches Büro , which may be rendered literally as "office of politics" or idiomatically as "political party steering committee", became Politbüro . Syllabic abbreviations are not only used in politics, however. Many business names, trademarks, and service marks from across Germany are created on the same pattern: for

Such shorthand can be an abbreviation, such as "in" for " inch " or can be
1584-834: The subject of a verb but sometimes does not indicate any particular relationship with the other parts of a sentence. In some languages, the nominative case is unmarked, and it may then be said to be marked by a null morpheme . Moreover, in most languages with a nominative case, the nominative form is the lemma ; that is, it is the reference form used to cite a word, to list it as a dictionary entry etc. Nominative cases are found in Albanian , Arabic , Estonian , Sanskrit , Slovak , Ukrainian , Hungarian , Lithuanian , Georgian , German , Latin , Greek , Icelandic , Old English , Old French , Polish , Serbian , Czech , Romanian , Russian and Pashto , among other languages. English still retains some nominative pronouns , which are contrasted with

For instance, a household composed of two widowed sisters living on their income has no wage earner. The survey director should request that the initials "n a" ("not applicable") be written down opposite such questions. No space should be left blank. The guide goes on to indicate that every blank should be filled, even if only to indicate that

The term "nominative case" is most properly used in the discussion of nominative–accusative languages , such as Latin, Greek and most modern Western European languages. In active–stative languages , there is a case, sometimes called nominative, that is the most marked case and
