Usage in English


Historical development

The apostrophe was first used by Pietro Bembo in his edition of '' De Aetna'' (1496). It was introduced into English in the 16th century in imitation of French practice.

(1529), the apostrophe was used in place of a vowel letter to indicate elision (as in in place of ). It was also frequently used in place of a final "e" (which was still pronounced at the time) when it was elided before a vowel, as in . Modern French

Early English practice

From the 16th century, following French practice, the apostrophe was used when a vowel letter was omitted either because of incidental elision ("I'm" for "I am") or because the letter no longer represented a sound ("lov'd" for "loved").

The plural genitive did not use the "-es" inflection, and since many plural forms already consisted of the "-s" or "-es" ending, using the apostrophe in place of the elisioned "e" could lead to singular and plural possessives of a given word having the exact same spelling.

Possessive apostrophe

The apostrophe is used in English to indicate what is, for historical reasons, misleadingly called the possessive case in the English language. This case was called the genitive until the 18th century and, like the genitive case in other languages, expresses relationships other than
possession Possession may refer to: Law * Dependent territory, an area of land over which another country exercises sovereignty, but which does not have the full right of participation in that country's governance * Drug possession, a crime * Ownership * ...
. For example, in the expressions "the school's headmaster", "the men's department", and "tomorrow's weather", the school does not own/possess the headmaster, men do not own/possess the department, and tomorrow does not/will not own the weather. In the words of Merriam-Webster's Dictionary of English Usage: This dictionary also cites a study that found that only 40% of the possessive forms were used to indicate actual possession. The modern spelling convention distinguishes possessive singular forms ("Bernadette's", "flower's", "glass's", "one's") from simple plural forms ("Bernadettes", "flowers", "glasses", "ones"), and both of those from possessive plural forms ("Bernadettes'", "flowers'", "glasses'", "ones'"). For example, the word "glass's" is the singular possessive form of the noun "glass". The plural form of "glass" is "glasses" and the plural possessive form is, therefore, "glasses'". You would therefore say "I drank the glass's contents" to indicate drinking a drink, but "I drank the glasses' contents" when you've finished your second drink. For singular forms, the modern possessive or genitive inflection is a survival from certain genitive inflections in Old English, for which the apostrophe originally marked the loss of the old "e" (for example, became ). Until the 18th century, the apostrophe was extensively used to indicate plural forms. Its use for indicating plural "possessive" forms was not standard before the middle of the 19th century.


General principles for the possessive apostrophe


= Summary of rules for most situations

= * Possessive personal pronouns, serving as either noun-equivalents or adjective-equivalents, do not use an apostrophe, even when they end in "s". The complete list of those ending in the letter "s" or the corresponding sound or but not taking an apostrophe is "ours", "yours", "his", "hers", "its", "theirs", and "whose". * Other pronouns, singular nouns not ending in "s", and plural nouns not ending in "s" all take s" in the possessive: e.g., "someone's", "a cat's toys", "women's". * Plural nouns already ending in "s" take only an apostrophe after the pre-existing "s" to form the possessive: e.g., "three cats' toys".


= Basic rule (singular nouns)

= For most singular nouns the ending s" is added; e.g., "the cat's whiskers". *If a singular noun ends with an "s"-sound (spelled with "-s", "-se", for example), practice varies as to whether to add s" or the apostrophe alone. In many cases, both spoken and written forms differ between writers (see details below). * Acronyms and initialisms used as nouns (CD, DVD, NATO, RADAR, etc.) follow the same rules as singular nouns: e.g., "the TV's picture quality".


= Basic rule (plural nouns)

= When the noun is a normal plural, with an added "s", no extra "s" is added in the possessive; so "the neighbours' garden" (there is more than one neighbour owning the garden) is standard rather than "the neighbours's garden". * If the plural is not one that is formed by adding "s", an "s" is added for the possessive, after the apostrophe: "children's hats", "women's hairdresser", "some people's eyes" (but compare "some peoples' recent emergence into nationhood", where "peoples" is meant as the plural of the singular "people"). These principles are universally accepted. * A few English nouns have plurals that are not spelled with a final "s" but nevertheless end in an /s/ or a /z/ sound: "mice" (plural of "mouse"; also in compounds like "
dormouse A dormouse is a rodent of the family Gliridae (this family is also variously called Myoxidae or Muscardinidae by different taxonomists). Dormice are nocturnal animals found in Africa, Asia, and Europe. They are named for their long, dormant hibe ...

titmouse ''Baeolophus'' is a genus of birds in the family Paridae. Its members are commonly known as titmice. All the species are native to North America. In the past, most authorities retained ''Baeolophus'' as a subgenus within the genus ''Parus ...
"), " dice" (when used as the plural of "die"), "pence" (a plural of "penny", with compounds like "sixpence" that now tend to be taken as singulars). In the absence of specific exceptional treatment in style guides, the possessives of these plurals are formed by adding an apostrophe and an "s" in the standard way: "seven titmice's tails were found", "the dice's last fall was a seven", "his few pence's value was not enough to buy bread". These would often be rephrased, where possible: "the last fall of the dice was a seven".


= Basic rule (compound nouns)

= Compound nouns have their singular possessives formed with an apostrophe and an added ''s'', in accordance with the rules given above: ''the Attorney-General's husband''; ''the Lord Warden of the Cinque Ports's prerogative''; ''this Minister for Justice's intervention''; ''her father-in-law's new wife''. *In such examples, the plurals are formed with an ''s'' that does not occur at the end: e.g., ''attorneys-general''. A problem therefore arises with the ''possessive'' plurals of these compounds. Sources that rule on the matter appear to favour the following forms, in which there is both an ''s'' added to form the plural, and a separate '''s'' added for the possessive: ''the attorneys-general's husbands''; ''successive Ministers for Justice's interventions''; ''their fathers-in-law's new wives''. Because these constructions stretch the resources of punctuation beyond comfort, in practice they are normally reworded: ''interventions by successive Ministers for Justice''.


= Joint or separate possession

= For two nouns (or noun phrases) joined by ''and'', there are several ways of expressing possession, including: :1. marking of the last noun (e.g. "Jack and Jill's children") :2. marking of both nouns (e.g. "Jack's and Jill's children"). Some grammars make no distinction in meaning between the two forms. Some publishers' style guides, however, make a distinction, assigning the "segregatory" (or "distributive") meaning to the form "John's and Mary's" and the "combinatorial" (or "joint") meaning to the form "John and Mary's". A third alternative is a construction of the form "Jack's children and Jill's", which is always distributive, i.e. it designates the combined set of Jack's children and Jill's children. When a coordinate possessive construction has two personal pronouns, the normal possessive inflection is used, and there is no apostrophe (e.g., "his and her children"). The issue of the use of the apostrophe arises when the coordinate construction includes a noun (phrase) and a pronoun. In this case, the inflection of only the last item may sometimes be, at least marginally, acceptable ("you and your spouse's bank account"). The inflection of both is normally preferred (e.g. Jack's and your dogs), but there is a tendency to avoid this construction, too, in favour of a construction that does not use a coordinate possessive (e.g. by using "Jack's letters and yours"). Where a construction like "Jack's and your dogs" is used, the interpretation is usually "segregatory" (i.e. not joint possession).


= With other punctuation; compounds with pronouns

= If the word or compound includes, or even ends with, a punctuation mark, an apostrophe and an ''s'' are still added in the usual way: "
Westward Ho! Westward Ho! is a seaside village near Bideford in Devon, England. The A39 road provides access from the towns of Barnstaple, Bideford, and Bude. It lies at the south end of Northam Burrows and faces westward into Bideford Bay, opposite Sau ...
's railway station"; "''Awaye!'''s Paulette Whitten recorded Bob Wilson's story"; ''Washington, D.C.'s museums'' (assuming that the prevailing style requires full stops in ''D.C.).'' *If the word or compound already includes a possessive apostrophe, a double possessive results: ''Tom's sisters' careers''; ''the head of marketing's husband's preference''; ''the master of foxhounds' best dog's death''. Many style guides, while allowing that these constructions are possible, advise rephrasing: ''the head of marketing's husband prefers that...''.

= Time, money, and similar

= An apostrophe is used in time and money references in constructions such as ''one hour's respite'', ''two weeks' holiday'', ''a dollar's worth'', ''five pounds' worth'', ''one mile's drive from here''. This is like an ordinary possessive use. For example, ''one hour's respite'' means ''a respite of one hour'' (exactly as ''the cat's whiskers'' means ''the whiskers of the cat'').


= Possessive pronouns and adjectives

= No apostrophe is used in the following possessive pronouns and adjectives: ''yours'', ''his'', ''hers'', ''ours'', ''its'', ''theirs'', and ''whose''. All other possessive pronouns do end with an apostrophe and an ''s''. In singular forms, the apostrophe comes first, e.g. ''one's''; ''everyone's''; ''somebody's'', ''nobody else's'', etc., while the apostrophe follows the ''s'' in plural forms as with nouns: ''the others' complaints''. The possessive of ''it'' was originally ''it's'', and it's a common mistake today to write ''its'' this way, though the apostrophe was dropped by the early 1800s and authorities are now unanimous that ''it's'' can be only a contraction of ''it is'' or ''it has''.

Singular nouns ending with an "s" or "z" sound

Some singular nouns are pronounced with a sibilant sound at the end: /s/ or /z/. The spelling of these ends with ''-s'', ''-se'', ''-z'', ''-ze'', ''-ce'', ''-x'', or ''-xe''. Many respected authorities recommend that practically all singular nouns, including those ending with a sibilant sound, have possessive forms with an extra ''s'' after the apostrophe so that the spelling reflects the underlying pronunciation.

Others prefer to add '''s'': ''for convenience's sake''. Still others prefer to omit the apostrophe when there is an ''s'' sound before ''sake'': ''for morality's sake'', but ''for convenience sake''.


Nouns ending with silent ''s'', ''x'', or ''z''

The English possessive of French nouns ending in a silent ''s'', ''x'', or ''z'' is addressed by various style guides. Certainly a sibilant is pronounced in examples like ''Descartes's'' and ''Dumas's''; the question addressed here is whether ''s'' needs to be added. Similar examples with ''x'' or ''z'': s main ingredient is truffle''; ''His 's loss went unnoticed''; ''"Verreaux('s) eagle, a large, predominantly black eagle, ''Aquila verreauxi'',..."'' (

(with nearby sibilants ''-ce-'' in ''noces'' and ''s-'' in ''singular''). Compare treatment of other titles, above. Guides typically seek a principle that will yield uniformity, even for foreign words that fit awkwardly with standard English punctuation.


Possessives in geographic names

Place names in the United States do not use the possessive apostrophe on federal maps and signs. The United States Board on Geographic Names, which has responsibility for formal naming of municipalities and geographic features, has deprecated the use of possessive apostrophes since 1890 so as not to show ownership of the place. Only five names of natural features in the US are officially spelled with a genitive apostrophe: Martha's Vineyard; Ike's Point, New Jersey; John E's Pond, Rhode Island; Carlos Elmer's Joshua View, Arizona; and Clark's Mountain, Oregon.US Board on Geographic Names: FAQs

''. Usage is variable and inconsistent. Style guides typically advise consulting an official source for the standard form of the name (as one would do if uncertain about other aspects of the spelling of the name); some tend towards greater prescriptiveness, for or against such an apostrophe. As the case of ' shows, it is not possible to analyze these forms simply as non-possessive plurals, since ''women'' is the only correct plural form of ''woman''.

Apostrophe showing omission

An apostrophe is commonly used to indicate omitted characters, normally letters: * It is used in contractions, such as ''can't'' from ''cannot'', ''it's'' from ''it is'' or ''it has'', and ''I'll'' from ''I will'' or ''I shall''. * It is used in abbreviations, as ''gov't'' for ''government''. It may indicate omitted numbers where the spoken form is also capable of omissions, as '''70s'' for ''1970s'' representing ''seventies'' for ''nineteen-seventies''. In modern usage, apostrophes are generally omitted when letters are removed from the start of a word, particularly for a

. For example, it is not common to write '''bus'' (for ''omnibus''), '''phone'' (''telephone''), '''net'' (''Internet''). However, if the shortening is unusual, dialectal or archaic, the apostrophe may still be used to mark it (e.g., '''bout'' for ''about'', '''less'' for ''unless'', '''twas'' for ''it was''). Sometimes a misunderstanding of the original form of a word results in a non-standard contraction. A common example: '''til'' for ''until'', though ''till'' is in fact the original form, and ''until'' is derived from it. **The spelling ''fo'c's'le'', contracted from the nautical term ''forecastle'', is unusual for having three apostrophes. The spelling ''bo's'n's'' (from ''boatswain's''), as in ''Bo's'n's Mate'', also has three apostrophes, two showing omission and one possession. ''Fo'c's'le'' may also take a possessive ''s'' – as in ''the fo'c's'le's timbers'' – giving four apostrophes in one word. A word which formerly contained two apostrophes is ''sha'n't ''for ''shall not'', examples of which may be found in the older works of

Use in forming some plurals

Following an evolution in usage in the 20th century, today "the apostrophe of plurality continues in at least five areas": abbreviations, letters of the alphabet/small words, numbers, family names, and in non-standard use.


Abbreviations

For abbreviations, including acronyms, the use of ''s'' without an apostrophe is now more common than its use with an apostrophe. Most modern style guides disparage the use of apostrophes in all plural abbreviations. Some references continue to condone their use, or even recommend their use in some abbreviations. For example, ''The Canadian Style'' states "Add an apostrophe and ''s'' to form the plural of abbreviations containing more than one period", so ''G.M.'s'' is preferred to ''G.M.s''. The ''

to the English Language'' condones ''V.I.P.'s'', ''VIP's'', and ''VIPs'' equally.


Letters of the alphabet, and small words

For single lowercase letters, pluralization with '''s'' is usual. Many guides recommend apostrophes whether the single letters are lowercase (as in " minding your p's and q's") or uppercase (as in "A's and S's"). ''

requires the use of italics instead of an apostrophe: ''p''s, ''n''s, etc. In the phrase ''dos and don'ts'', most modern style guides disparage spelling the first word as ''do's''. However, there is a lack of consensus and certainly the use of an apostrophe continues, legitimately, in which "the apostrophe of plurality occurs in the first word but not the second".


Numbers and symbols

to the English Language'' notes that "a plural ''s'' after a set of numbers is often preceded by an apostrophe, as in ''3's and 4's''..., but many housestyles and individuals now favour ''3s and 4s''". Most style guides prefer the lack of apostrophe for groups of years (e.g. ''1980s'') and will prefer ''90s'' or '''90s'' over ''90's'' or '''90's''. While many guides discourage using an apostrophe in all numbers/dates, many other guides ''encourage'' using an apostrophe for numbers or are divided on the issue; for example, the ''Australian Government Style Manual'' recommends "Binary code uses 0’s and 1’s" but recommends "the 2020s". Still other guides take a laissez-faire approach. For example, the University of Sussex's online guide notes regional variation in the use of apostrophes in dates,Guide to Punctuation
Larry Trask, University of Sussex: "American usage, however, does put an apostrophe here: (A) This research was carried out in 1970's."
and slightly prefers ''1's and 7's'' over ''1s and 7s'' but condones both. The apostrophe is very often used in plurals of symbols, for example "that page has too many &'s and #'s on it". Some style guides state that the apostrophe is unnecessary since there is no ambiguity but that some editors and teachers prefer this usage. The addition of an ''s'' without an apostrophe may make the text difficult to read. For many numbers and symbols, a useful alternative is to write out the numbers as words (e.g. ''thousands'' instead of ''1000's'' or ''1000s'', and ''ampersands'' instead of ''&s'' or ''&'s'').


Family names

The vast majority of English references published from the late 20th century onwards disparage the use of apostrophes in family-name plurals, for example identifying ''Joneses'' as correct and ''Jones's'' as incorrect. As an exception, the ''
Oxford Companion ''Oxford Companions'' is a book series published by Oxford University Press Oxford University Press (OUP) is the university press of the University of Oxford. It is the largest university press in the world, and its printing history dates ...
to the English Language'' (2018) reports that, in addition to ''Joneses'' etc., standard apostrophe usage does continue "in family names, especially if they end in ''-s'', as in '' keeping up with the Jones's''".

surnames use an apostrophe after an ''M'', for example ''M'Gregor''. The apostrophe here may be seen as marking a contraction where the prefix ''Mc'' or '' Mac'' would normally appear. However, it may also arise from a misinterpretation of printers' use of an inverted comma, (''turned comma'' or "6-quote"), as a substitute for superscript ''c'' when printing with hand-set metal type. Compare: M'Lean, McLean, M‘Lean.

Non-standard English use

Failure to observe standard use of the apostrophe is widespread and frequently criticised as incorrect, often generating heated debate. The British founder of the Apostrophe Protection Society earned a 2001 Ig Nobel prize for "efforts to protect, promote and defend the differences between plural and possessive". A 2004 report by British examination board OCR stated that "the inaccurate use of the apostrophe is so widespread as to be almost universal". A 2008 survey found that nearly half of the UK adults polled were unable to use the apostrophe correctly.Half of Britons struggle with the apostrophe

Non-English use


As a mark of elision

In many languages, especially European languages, the apostrophe is used to indicate the elision of one or more sounds, as in English. *In Albanian the apostrophe is used to show that a vowel has been omitted from words, especially in different forms of verbs and in some forms of personal pronoun. For example, : them (from : them), (from ). It is used too in some of the forms of possessive pronouns, for example: (from ). *In

, as in Dutch, the apostrophe is used to show that letters have been omitted from words. The most common use is in the indefinite article , which is a contraction of ''een'' meaning 'one' (the number). As the initial ''e'' is omitted and cannot be capitalised, the second word in a sentence that begins with is capitalised instead. For example: , 'A tree is green'. In addition, the apostrophe is used for plurals and diminutives where the root ends with long

, this elision is represented in the orthography with an apostrophe: in ' 'the father of the children', ' ('of') becomes ''w''; in ' ('who is it?'), ' ('who') becomes ''y''. But the final vowel of a polysyllable is always written, even if it is elided in speech: ' ('this man'), not *', because ' ('man') is a polysyllable. * In German an apostrophe is used almost exclusively to indicate omitted letters. It must not be used for plurals or most of the possessive forms. The only exceptions are the possessive cases of names ending in an "s"-sound as in ', or "to prevent ambiguities" in all other possessive cases of names, as in ' (referring to the female name ', not the male name '). The English/Saxon style of using an apostrophe for possession was introduced after the spelling reform, but is strongly disagreed on by native speakers, and discouraged.

, the apostrophe marks that a word has been contracted, such as ' from ' ('have/has not'). Unlike English and French, such elisions are not accepted as part of standard orthography but are used to create a more "oral style" in writing. The apostrophe is also used to mark the genitive for words that end in an -s sound: words ending in -s, -x, and -z, some speakers also including words ending in the sound . As Norwegian doesn't form the plural with -s, there is no need to distinguish between an -s forming the possessive and the -s forming the plural. Therefore, we have ' ('man') and ' ('man's'), without apostrophe, but ' ('naval pilot') and '' ('naval pilot's').

Also, no apostrophe is used in the word ''pra'', the reduced or popular form of the preposition ''para''. * Modern Spanish no longer uses the apostrophe to indicate elision in standard writing, although it can sometimes be found in older poetry for that purpose. Instead Spanish writes out the spoken elision in full (', ') except for the contraction ' for ' + ', and ''al'' for ''a'' + ''el,'' which use no apostrophe. Spanish also switches to a form that is identical to the masculine article (but is actually a variant of the feminine article) immediately before a feminine noun beginning with a stressed ''a'' instead of writing (or saying) an elision: ', ', and ' but ' and '.

The formal way to denote elision in Swedish is by using colon, e.g. ' for ' which is rarely spelled out in full.

(for example, 17°54′32″ represents 17 degrees 54 minutes and 32 seconds). Similarly in mathematics, the prime is generally used to generate more variable names for similar things without resorting to subscripts, with ''x''′ generally meaning something related to (or derived from) ''x''. Because of the very close similarity of the typewriter apostrophe and typewriter double quote to prime and double prime, substitution in informal contexts is ubiquitous but they are deprecated in contexts where proper typography is important. There is also a risk of an automatic process 'correcting' a typewriter apostrophe to a typographic apostrophe, which will not make sense if a prime symbol was intended.

Many earlier (pre-1985) computer displays and printers rendered the ASCII apostrophe as a typographic apostrophe, and rendered the grave accent ('back tick', 0x60, 96) as a matching left single quotation mark. This allowed a more typographic appearance of text: ``I can't'' would appear as on these systems. This can still be seen in many documents prepared at that time, and is still used in the

Entering apostrophes

Although ubiquitous in typeset material, the typographic apostrophe (  ) is rather difficult to enter on a computer, since it does not have its own key on a standard keyboard. Outside the world of professional typesetting and graphic design, many people do not know how to enter this character and instead use the typewriter apostrophe ( ' ). The typewriter apostrophe has always been considered tolerable on Web pages because of the egalitarian nature of Web publishing, the low resolution of computer monitors in comparison to print, and legacy limitations provided by ASCII. More recently, the standard use of the typographic apostrophe is becoming more common on the Web due to the wide adoption of the

Smart quotes

and publishing software often convert typewriter apostrophes to typographic apostrophes during text entry (at the same time converting opening and closing single and double quotes to their standard left-handed or right-handed forms). A similar facility may be offered on web servers after submitting text in a form field, e.g. on weblogs or free encyclopedias. This is known as the ''smart quotes'' feature; apostrophes and quotation marks that are not automatically altered by computer programs are known as ''dumb quotes''. Such conversion is not always correct. Smart quotes features often incorrectly convert a leading apostrophe to an opening quotation mark (e.g., in abbreviations of years: ''29'' rather than the correct ''29'' for the years ''1929'' or ''2029'' (depending on context); or ''twas'' instead of ''twas'' as the archaic abbreviation of ''it was''). Smart quote features also often fail to recognise situations when a

it is possible to turn smart quotes off (in some versions, by navigating through ''Tools'', ''AutoCorrect'', ''AutoFormat as you type'', and then unchecking the appropriate option). Alternatively, typing Control-Z (for ''Undo'') immediately after entering the apostrophe will convert it back to a typewriter apostrophe. In Microsoft Word for Windows, holding down the Control key while typing two apostrophes will produce a single typographic apostrophe.
