Possessives

*

Plural nouns not ending in s, add ’s: the alumni’s newsletter, the children’s playground.
*

Plural nouns ending in s, add only an apostrophe: the girls’ locker room, the students’ newspaper.
*

Nouns that are the same in singular and plural are treated as plurals – chassis, corps, deer.
*

Singular nouns not ending in s, add ’s: the book’s pages, the pen’s ink.
*

Singular common nouns ending in s, add ’s unless the next word begins with s: the witness’s chair, the witness’ seat.
*

If a singular proper noun ends in s, add an apostrophe: The University of Texas at Dallas’ campus.

Pronouns: Personal interrogative and relative pronouns have several forms for the possessive that do not involve an apostrophe: mine, ours, your, yours, his, hers, its, theirs, whose. If you are using an apostrophe with a pronoun, make sure that the meaning calls for a contraction: you’re, it’s, there’s, who’s.
