Apostrophe

Apostrophes are hard-working little punctuation marks that can indicate a number of different things.

They are mainly used to show possession and in contractions. Let's take a look at how that works.

Possession

Apostrophes indicate when something belongs to someone. With singular nouns, you add -'s to show possession:

  • Ann's bag is full.

Adding the -'s shows that the bag belongs to Ann.

Here are a few more examples:

  • That must be my dog's bone.
  • Andy's plan will not succeed.
  • Meg's favorite game is Settlers of Catan.

If you want to show that a plural noun has possession, then the apostrophe goes at the end of the word:

  • The kids' books are in the library.

Contractions

Contractions are two words that are joined together, often used to show a more casual or colloquial way of writing. Apostrophes take the place of the missing letters that occur when the two words are joined:

  • do not = don't
  • could not = couldn't
  • will not = won't
  • they are = they're
  • should have = should've

Remember, the apostrophe takes the place of the missing letters and words.
