Possessives

A possessive demonstrates ownership of something. Use the following guidelines to correct spelling errors that involve possessives.

To create a possessive with a singular noun or a plural noun that does not end in s, add an apostrophe and an s. Remember that if you add only an s without an apostrophe, your reader will think the word is a plural noun rather than a possessive singular noun.

• Incorrect: The dogs fur looked nice and shiny after his bath.
  Correct: The dog’s fur looked nice and shiny after his bath.

• Incorrect: I noticed this morning that my boss’ car had a huge dent.
  Correct: I noticed this morning that my boss’s car had a huge dent.

• Incorrect: My families lake house is the best place in the world.
  Correct: My family’s lake house is the best place in the world.

To create a possessive with a plural noun that ends in s, just add an apostrophe. This includes plural nouns that end in ies.

• Incorrect: I can’t find the boys’s pajamas.
  Correct: I can’t find the boys’ pajamas.

• Incorrect: The recipes should list all the different drinks ingredients.
  Correct: The recipes should list all the different drinks’ ingredients.

• Incorrect: All the different companies’s parking lots are on the south side of the building.
  Correct: All the different companies’ parking lots are on the south side of the building.

With possessive pronouns (his, hers, ours, yours, whose, theirs, its), you do not need to use apostrophes. When preceding a noun, his, her, our, your, whose, and their, you don’t need an s because they are already possessive.

• Incorrect: My mom told me she wants her car back in it’s normal spot in the garage by midnight.
  Correct: My mom told me she wants her car back in its normal spot in the garage by midnight.
