-'s 2 Syllabification: -'s

suffix

Denoting the plural of a letter or symbol: T’s 9's

Usage

In the formation of plurals of regular nouns, it is incorrect to use an apostrophe: six pens (not six pen’s). There are a few special occasions, however, in which the apostrophe indicates plurals, as with letters and symbols where s added without punctuation would look odd (or be undecipherable): ABC’s; the five W’s; dot your i’s and cross your t’s; the code is two H’s followed by four #’s.
