Apostrophe Usage

Writers may forget to use apostrophes or may use them incorrectly. Apostrophes are used to (a) indicate possession or ownership and (b) to form a contraction. If the noun is singular, place the apostrophe before the “s”. If the noun is plural, the apostrophe is placed after the “s”.

Tip: 

Make the noun plural first and then show possession.
