Possessive apostrophe

 -es, which evolved into a simple -s for the possessive ending. An apostrophe was later added to mark the omitted e.

Joint and separate possession A distinction is made between joint possession (Jason and Sue's emails: the emails between Jason and Sue, or from them jointly) and separate possession (Jason's and Sue's emails: the emails of Jason and the emails of Sue). Style guides differ only in how much detail they provide concerning these. Their consensus: in joint possession only the last possessor has possessive inflection; in separate possession all the possessors have possessive inflection. But if any of the possessors is indicated by a pronoun, then for both joint and separate possession all of the possessors have possessive inflection (His and her emails; His, her, and Anthea's emails; Jason's and her emails; His and Sue's emails; His and Sue's wedding; His and Sue's weddings).

General principles for the possessive apostrophe
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/ or a /z/ sound (spelled with -s, -se, -z, -ce, for example), practice varies as to whether to add 's or the apostrophe alone. A widely accepted practice is to follow whichever spoken form is judged better: the boss's shoes, Mrs Jones' hat (or Mrs Jones's hat, if that spoken form is preferred). In many cases, both spoken and written forms differ between writers. (See details below.)
Basic rule (plural nouns) When the noun is a normal plural, with an added s, no extra s is added in the possessive; so pens' caps (where there is more than one pen) is correct rather than pens's caps.
  • 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 end in an /s/ or a /z/ sound: mice (plural of mouse, and for compounds like dormouse
    Dormouse

    Dormice are rodents of the family Gliridae. . Dormice are mostly found in Europe, although some live in Africa and Asia. They are particularly known for their long periods of hibernation....
    , titmouse

    ), dice
    Dice

    A die is a small polyhedron object, usually cubic, used for generating Statistical randomnesss or other symbols. This makes dice suitable as gambling devices, especially for craps or sic bo, or for use in non-gambling tabletop games....
     (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
Lord Warden of the Cinque Ports

The Lord Warden of the Cinque Ports is a ceremonial official in the United Kingdom. The post dates from at least the 12th century but may be older....
' 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.


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: 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'
    Fox hunting

    Fox hunting is an activity involving the tracking, chase, and sometimes killing of a fox, traditionally a red fox, by trained foxhounds or other scent hounds, and a group of followers led by a master of foxhounds, who follow the hounds on foot or on horseback....
     best dog's death
    . Some style guides, while allowing that these constructions are possible, advise rephrasing: the preference of the head of marketing's husband. If an original apostrophe, or apostrophe with s, occurs at the end, it is left by itself to do double duty: Our employees are better paid than McDonald's employees; Standard & Poor's indexes are widely used; the B-52's greatest hits (the fixed forms of McDonald's

    (despite the fact that the single word hers is spelled without an apostrophe, see below in this section; His 'n' Hers's first track is theoretically possible, but unlikely unless an extra sibilant is actually pronounced after Hers). For complications with foreign phrases and titles, see below.
Time, money, and similar An apostrophe is used in time and money references, among others, 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). Exceptions are accounted for in the same way: three months pregnant (in modern usage, we do not say pregnant of three months).

Possessive pronouns and adjectives No apostrophe is used in the following possessive pronouns and adjectives: yours, his, hers, ours, its, theirs, and whose. (Many people wrongly use it's for the possessive of it, but authorities are unanimous that it's can only be a contraction of it is or it has.) All other possessive pronouns ending in s do take an apostrophe: one's; everyone's; somebody's, nobody else's, etc. With plural forms, the apostrophe follows the s, as with nouns: the others' husbands (but compare They all looked at each other's husbands, in which both each and other are singular).

Singular nouns ending with an "s" or "z" sound
This subsection deals with singular nouns 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 sources have required that practically all singular nouns, including those ending with a sibilant sound, have possessive forms with an extra s after the apostrophe. Examples include the Modern Language Association and The Economist

. Such sources would demand possessive singulars like these: Senator Jones's umbrella; Mephistopheles's cat. On the other hand, some modern writers omit the extra s in all cases, and Chicago Manual of Style allows this as an "alternative practice". Generally, Chicago Manual of Style is in line with the majority of current guides, and recommends the traditional practice but provides for several exceptions to accommodate spoken usage, including the omission of the extra s after a polysyllabic word ending in a sibilant. Rules that modify or extend the standard principle have included the following:
  • If the singular possessive is difficult or awkward to pronounce with an added sibilant, do not add an extra s; these exceptions are supported by The Guardian

Apostrophe

The apostrophe is a punctuation mark, and sometimes a diacritic mark, in languages that use the Latin alphabet or certain other alphabets. In English it has two main functions: it marks omissions, and it assists in marking the possessives of all nouns and many pronouns....
.

Some writers like to reflect standard spoken practice in cases like these with sake: for convenience' sake, for goodness' sake, for appearance' sake, for compromise' sake, etc. This punctuation is preferred in major style guides. 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 rendered differently by different authorities. Some prefer Descartes' and Dumas', while others insist on Descartes's and Dumas's. Certainly a sibilant is pronounced in these cases; the theoretical question is whether the existing final letter is sounded, or whether s needs to be added. Similar examples with x or z: Sauce Périgueux's main ingredient is truffle; His pince-nez's loss went unnoticed; "Verreaux('s) eagle, a large, predominantly black eagle, Aquila verreauxi,..." (OED, entry for "Verreaux", with silent x; see Verreaux's eagle
Verreaux's Eagle

Verreaux's Eagle , also known as the African Black Eagle or Black Eagle, is a large bird of prey. This eagle is a resident breeder throughout Africa, especially sub-Saharan Africa, and can usually be found in mountainous regions....
); in each of these some writers might omit the added s. The same principles and residual uncertainties apply with "naturalised" English words, like Illinois and Arkansas.

For possessive plurals of words ending in silent x, z, or s, the few authorities that address the issue at all typically call for an added s, and require that the apostrophe precede the s: The Loucheux's homeland is in the Yukon; Compare the two Dumas's literary achievements. The possessive of a cited French title with a silent plural ending is uncertain: "Trois femmes's long and complicated publication history", but "Les noces' singular effect was 'exotic primitive'..." (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.

). The special circumstances of the latter case may be this: the customary pronunciation of this place name is reflected in the addition of an extra -s; since usage is firmly against a doubling of the final -s without an apostrophe, this place name has an apostrophe. This could be regarded as an example of a double genitive: it refers to the park of the church of St James. None of this detracts from the fact that omission of the apostrophe in geographical names is becoming a clear standard in most English-speaking countries, including Australia. Practice in Britain and Canada is not so uniform.

Possessives in names of organizations
Sometimes the apostrophe is omitted in the names of clubs, societies, and other organizations, even though the standard principles seem to require it: Country Women's Association

The Country Women?s Association of Australia is the largest women's organisation in Australia. It has 44,000 members across 1855 branches.

. Usage is variable and inconsistent. Style guides typically advise consulting an official source for the standard form of the name; some tend towards greater prescriptiveness, for or against such an apostrophe. As the case of womens shows, it is not possible to analyse these forms simply as non-possessive plurals, since women is the only correct plural form of woman.

Possessives in business names
Where a business name is based on a family name, it may or may not take an apostrophe (compare Sainsbury's and Harrods

Apostrophe showing omission

An apostrophe is commonly used to indicate omitted characters:

  • It is used in contraction
    Contraction (grammar)

    In current English usage, contraction is shortening of a word, syllable, or word group by omission of internal letters.In traditional grammar, contraction can denote the formation of a new word from one word or a group of words, for example, by elision....
    s, 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 abbreviation
    Abbreviation

    An abbreviation is a shortened form of a word or phrase. Usually, but not always, it consists of a letter or group of letters taken from the word or phrase....
    s, as gov't for government, or '70s for 1970s. In modern usage, apostrophes are generally omitted when letters are removed from the start of a word. 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 an incorrect 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 notable 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.

Use in forming certain plurals

An apostrophe is used by some writers to form a plural
English plural

In the English language, nouns are inflection for grammatical number?that is, Grammatical number or plural. This article discusses the variety of ways in which English plurals are formed....
 for abbreviations, acronyms, and symbols where adding just s rather than s may leave things ambiguous or inelegant. Some specific cases:
  • It is generally acceptable to use apostrophes to show plurals of single lower-case letters, such as be sure to dot your i's and cross your t's. Some style guides would prefer to use a change of font: dot your is and cross your ts. Upper case letters need no apostrophe (I got three As in my exams) except when there is a risk of misreading, such as at the start of a sentence: A's are the highest marks achievable in these exams.
  • For groups of years, the apostrophe at the end cannot be regarded as necessary, since there is no possibility of misreading. For this reason, most authorities prefer 1960s to 1960's (although the latter is noted by at least one source as acceptable in American usage), and 90s or '90s to 90's or '90's.
  • The apostrophe is sometimes used in forming the plural of numbers (for example, 1000's of years); however, as with groups of years, it is unnecessary: there is no possibility of misreading. Most sources are against this usage.
  • The apostrophe is often used in plurals of symbols. Again, since there can be no misreading, this is often regarded as incorrect. That page has too many &s and #s on it.
  • Finally, a few sources accept its use in an alternative spelling of the plurals of a very few short words, such as do, ex, yes, no, which become do's, ex's, etc. In each case, dos, exes, yeses (or yesses) and noes would be preferred by most authorities. Nevertheless, many writers are still inclined to use such an apostrophe when the word is thought to look awkward or unusual without one.


Use in non-English names

Names that are not strictly native to English sometimes have an apostrophe substituted to represent other characters (see also As a mark of elision, below).

    's campaign". In this example, Ala is spelt without an apostrophe, since its spelling and pronunciation fit into normal Polish rules; but Gore'a needs the apostrophe, because e disappears from the pronunciation, changing the inflection pattern. This rule is often misunderstood as calling for an apostrophe after all foreign words, regardless of their pronunciation, yielding Kampania Al'a Gore'a, for example. The effect is akin to the greengrocers' apostrophe (see above).

Computing

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 ( ' ). However, because typewriter apostrophes are now often automatically converted to typographic apostrophes by wordprocessing and desktop-publishing software (see below), the typographic apostrophe does often appear in documents produced by non-professionals.

The typewriter apostrophe has always been considered tolerable on Web pages because of the egalitarian nature of Web publishing and the low resolution of computer monitors in comparison to print. More recently, the correct use of the typographic apostrophe is becoming more common on the Web due to the wide adoption of the Unicode

Nevertheless, the tradition of using the typewriter apostrophe continues in most situations.

Smart Quotes

Publishing

Publishing is the process of production and dissemination of literature or information – the activity of making information available for public view....
 software often converts typewriter apostrophes to typographic apostrophes during text entry (at the same time converting opening and closing single and double quotes to their correct 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 done in accordance with the standards for character sets and encodings. Additionally, many such software programs incorrectly convert a leading apostrophe to an opening quotation mark (e.g., in abbreviations of years: ''29'' rather than the correct ''29'' for the year ''2029''; or ''twas'' instead of ''twas'' as the archaic abbreviation of ''it was''. A quick way to get the correct result in Microsoft Word is to type two apostrophes (sometimes using a space as well, as required), and then delete the first. Smart quote features also often fail to recognise situations when a prime

 rather than an apostrophe is needed; for example, incorrectly rendering the latitude 49° 53′ 08″ as 49° 53 08.

In Microsoft Word it is possible to turn smart quotes off (in some versions, by navigating through ''Tools'', ''AutoCorrect'', ''AutoFormat as you type'', and then checking the appropriate option). Alternatively, typing CONTROL-Z (for ''Undo'') immediately after entering the apostrophe will convert it back to a straight apostrophe.

Typographic apostrophe and 8-bit encodings

Older 8-bit character encodings, like Windows CP1252, Mac Roman or ISO-8859-1, universally support the typewriter quote in the same position, 39, inherited from ASCII (as does Unicode; see below). However, most of them place the typographic apostrophe in different positions. ISO-8859-1, a common encoding used for web pages, omits the typographic apostrophe altogether.

Microsoft Windows CP1252 (sometimes incorrectly called ''ANSI'' or ''ISO-Latin'') is a duplicate of ISO-8859-1, with 27 additional characters in the place of control characters (in the range from 128 to 159). Microsoft software usually treats ISO-8859-1 as if it were CP1252. The wide adoption of Microsoft's web browser and web server has forced many other software makers to adopt this as a ''de facto'' convention – in some cases contravening established standards unnecessarily (e.g., some applications use CP1252 character values in HTML numeric references, where Unicode values are required, and would be sufficient for interoperation with MS software). Consequently, the typographic apostrophe and several other characters are handled inconsistently by web browsers and other software, and can cause interoperation problems.
