possessives

Possessives show possession or belonging, and are formed with the addition of an apostrophe + s to the end of a noun; e.g., “Sarah’s house”; “Tim’s car”.

Some of the most common mistakes with possessives is to confuse them with contracted words; i.e., words that have been shortened through the removal of certain letters. Who’s, for example, is a contraction of either who + is or who + has.
