The word apostrophe comes from the Greek ἡ ἀπόστροφος [προσῳδία] (hē apóstrophos [prosōidía], '[the accent of] turning away or elision'), through Latin and French.
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.
[19] If the word or compound includes, or ends with, a punctuation mark, an apostrophe and an s are still added in the usual way: "Westward Ho!
Most 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.
[28] Such authorities demand possessive singulars like these: Bridget Jones's Diary; Tony Adams's friend; my boss's job; the US's economy.
[41] For possessive plurals of words ending in a silent x, z or s, the few authorities that address the issue at all typically call for an added s and suggest that the apostrophe precede the s: The Loucheux's homeland is in the Yukon; Compare the two Dumas's literary achievements.
Guides typically seek a principle that will yield uniformity, even for foreign words that fit awkwardly with standard English punctuation.
[44][45] 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.
[48] Australia's Intergovernmental Committee on Surveying and Mapping also has a no-apostrophe policy, a practice it says goes back to the 1900s[49] and which is generally followed around the country.
Modern usage has been influenced by considerations of technological convenience including the economy of typewriter ribbons and films, and similar computer character "disallowance" which tend to ignore past standards.
A small activist group called the Apostrophe Protection Society[56] has campaigned for large retailers such as Harrods, Currys, and Selfridges to reinstate their missing punctuation.
[8] The Oxford Companion 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".
For example, the University of Sussex's online guide notes regional variation in the use of apostrophes in dates,[76] and slightly prefers 1's and 7's over 1s and 7s but condones both.
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 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".
For example: Rather than ʿ (modifier letter left half ring), the apostrophe is sometimes used to indicate a voiced pharyngeal fricative as it sounds and looks like the glottal stop to most English speakers.
The practice, once common and acceptable (see Historical development), comes from the identical sound of the plural and possessive forms of most English nouns.
Lynne Truss, author of Eats, Shoots & Leaves, points out that before the 19th century it was standard orthography to use the apostrophe to form a plural of a foreign-sounding word that ended in a vowel (e.g., banana's, folio's, logo's, quarto's, pasta's, ouzo's) to clarify pronunciation.
Some have argued that its use in mass communication by employees of well-known companies has led to the less literate assuming it to be standard and adopting the habit themselves.
Signs in Tesco advertise (among other items) "mens magazines", "girls toys", "kids books" and "womens shoes".
In his book Troublesome Words, author Bill Bryson lambasts Tesco for this, stating that "the mistake is inexcusable, and those who make it are linguistic Neanderthals.
[93] George Bernard Shaw, a proponent of English spelling reform on phonetic principles, argued that the apostrophe was mostly redundant.
[99] In a letter to the English Journal, Peter Brodie stated that apostrophes are "largely decorative ... [and] rarely clarify meaning".
"[102] In a Chronicle of Higher Education blog, Geoffrey Pullum proposed that apostrophe be considered a 27th letter of the alphabet, arguing that it is not a form of punctuation.
In that case, the letter 'ayn (Arabic ع and Hebrew ע) is correspondingly transliterated with the opening single quotation mark.
Later sans-serif typefaces had stylised apostrophes with a more geometric or simplified form, but usually retaining the same directional bias as a closing quotation mark.
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 most types of consumer keyboard.
A similar facility may be offered on web servers after submitting text in a form field, e.g. on weblogs or free encyclopedias.
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 unchecking the appropriate option).
