Make singular nouns possessive
Add an apostrophe and an s to the end of singular nouns, such as "book," and to indefinite pronouns, such as "another," to make them possessive. Do this even if the word ends in s.
Form the possessive plural of nouns
Make plural nouns ending in s, such as "cars," possessive by adding only an apostrophe. For irregular plurals that don't end in s, such as fish, add an apostrophe and s to the end.
Add apostrophe and s to compound nouns
Place an apostrophe and an s on the end of compound words, such as "father-in-law," to make them possessive.
Indicate ownership for two or more items by adding an apostrophe and s. For separate ownership, add an apostrophe and an s to each noun; for joint ownership, add an apostrophe and an s to the last noun.
Form contractions to combine two words by using an apostrophe where the omitted letters would go. For example, change do not to don't.
Form plurals of letters
Use an apostrophe and s in a few rare cases to form plurals of lowercase letters, such as in the phrase "p's and q's."
Avoid common errors
Avoid the common error of using apostrophes for personal pronouns such as "its," or plural nouns that are not possessive.
