   • 2012 April 15, Phil McNulty, “Tottenham 1-5 Chelsea”, in BBC‎:

     Before kick-off, a section of Chelsea’s support sadly let themselves and their club down by noisily interrupting the silence held in memory of the Hillsborough disaster and for Livorno midfielder Piermario Morosini, who collapsed and died after suffering a heart attack during a Serie B game on Saturday.

2. In the absence of a specified object, used to indicate “the house/place/establishment of”.

   We’re going to Luigi’s for dinner tonight. — that is, “Luigi’s house” or “Luigi’s restaurant”

   I'm going to the butcher’s for a steak.

   I bought it at Tesco's. (see s-form)

   You need a driver’s licence.

   These are popular boy’s T-shirts.

   Alex can be a girl’s name.

   That's a girl’s toy. (A toy intended for use by girls.) — Homographic to: That's a girl’s toy. (The toy of a specific girl.)

• -s (nonstandard; see for usage notes)

• of

• Irregular plurals with endings other than ‘s’ (e.g. children) always take ’s: the children’s voices.
• Words ending in s are made possessive in various ways. Consider:[1]
  • With regular plurals, the apostrophe is placed at the end, i.e. -s' is used (the dogs’ tails, whereas for singular ‘dog’, the dog’s tail).
  • The possessives of names which end in s may be formed using either this suffix (-'s) or bare -' (which see for more). Hence: St. James’s or St. James’, Chris's or Chris', Jesus's or Jesus'. The two suffixes may or may not be distinguished in pronunciation; for example, the BBC prescribes the following distinction:[2] (a) Dickens novel and Dickens’ novel /dɪkɪnz nɒvəl/, Dickens’s novel /dɪkɪnzɪz nɒvəl/.
• To remedy ambiguity or awkwardness in either speech or print, possessives can generally be recast using of: the tails of the dogs, the paths of St. James
• When referring to possessions of multiple people who don't share the same name, the standard, formal way to form the possessive is Jack’s and Jill’s pails. However, it is common to treat the pair of names as a noun phrase and to form the possessive of this instead, using only one ’s: Jack and Jill’s pails.

Equivalent to -s, with addition of apostrophe.

’s

1. (sometimes proscribed) Used to form the plurals of numerals, letters, some abbreviations and some nouns, usually because the omission of an apostrophe would make the meaning unclear or ambiguous.

   There are four 3’s in my phone number.

   “Banana” has three a’s and one b. (apostrophe "s" used so that the plural of “a” is not confused with the word “as”)

   You can buy CD’s in that shop.

   These are the do’s and don’ts. (apostrophe "s" used as “dos” may be misread)

2. (obsolete) Used to form plurals of foreign words, to clarify pronunciation, such as “banana’s” or “pasta’s”.[3]
3. (proscribed) Used to form the plural of nouns that correctly take just an "s" in the plural. See greengrocer’s apostrophe.

   Apple’s 50p a pound

The use of ’s to form plurals of initialisms or numerals is not currently recommended by most authorities, except when the meaning would otherwise be unclear. The use in foreign words was common before the 19th century, but is no longer accepted.[3] The use of the apostrophe in any other plural (as in “apple’s”) — the so-called “greengrocer’s apostrophe” — is proscribed.

1. Used to form the plural form of nouns ending in a vowel, except schwa.

   foto → foto’s (instead of fotoos)

   taxi → taxi’s (instead of taxies)

• -'

-’s

1. (archaic) Used to form the genitive of proper names
2. Used to form the genitive of proper names under certain circumstances.

• The use of -'s instead of -s is allowed, according to the German spelling reform of 1996, only when bare -s would be ambiguous (as in the example above). In informal writing it is sometimes used even when there is no ambiguity (e.g. Peter's), but this is proscribed.
