Usage notes

Usage with words ending in “s” varies and can be confusing.

With regular plurals, the apostrophe is placed at the end:

the dogs’ tails (whereas for singular ‘dog’: the dog’s tail)

Irregular plurals with endings other than ‘s’ (e.g. children) always take ’s:

the children’s voices

In current usage, the final “s” is sometimes dropped after proper names ending in “s”. This may reflect variations in pronunciation, or be an instance of (or case of confusion due to) the Biblical/classical name rule. In print, ambiguity can result, because s’ is also used to indicate a plural noun.

St. James’s or St. James’

(Where, technically, St. James’ could be read to indicate more than one St. James.)

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 strictly correct form is with the possessive of each person:

Jack’s and Jill’s pails

However, it is common to treat the pair of names as a noun phrase and to form its possessive instead, using only one ’s:

Jack and Jill’s pails

Suffix

1. Indicates a purpose or a user.You need a driver’s licence.These are popular boy’s T-shirts.Alex can be a girl’s name.

Usage notes

The particle ’s and the suffix ’s have the same origin but are grammatically different now.

(Particle) a girl’s name : The name of a specific girl. The particle combines with a girl.

(Suffix) a girl’s name : A female name. The suffix combines with girl.

Equivalent to -s, with arbitrary use of apostrophe.

Suffix

1. usage problem 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”.Lynn Truss. Eats, Shoots & Leaves. pp. 63–65.
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

Usage notes

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.

The use of the apostrophe in any other plural (as in “apple’s”) — the so-called “greengrocer’s apostrophe” — is incorrect.
