Apostrophes

Use an apostrophe

To form the possessive case of nouns. Add an apostrophe and an s, even if the noun ends in s, x, or z. To form the possessive of plural nouns that end in s, add only an apostrophe.

Examples

• the table's contents
• the box's contents
• users' accounts
• the Joneses' computer

To indicate a missing letter in a contraction.

Examples

• won't
• don't
• it's

Don’t use an apostrophe

• With a possessive pronoun.
• To form the plural of a singular noun.
