Apostrophes are punctuation marks used to indicate possession or ownership. The placement of an apostrophe depends upon the word that you are making possessive. Most words will require the addition of an apostrophe and an "s" to make the word possessive; however, there are a few exceptions, such as when the word is already plural with an "s."

Singular nouns ending in "s" still take an apostrophe and an additional "s" (e.g., Jones's theory).

Apostrophes are also used to create contractions, combinations of two words such as "can" and "not" combined to form "can’t." However, you should avoid using contractions in APA style.
