Possessive Nouns

Possessive nouns show ownership. See the highlighted examples below.

That is Mary's house.  The possessive noun in this sentence shows that the house belongs to Mary.

The book's cover is torn. The possessive noun in this sentence shows that the torn cover is part of, or belongs to the book.

The dog's collar is made of leather. The possessive noun in this sentence shows that the collar belongs to the dog.

The man's shirt is too small. The possessive noun in this sentence shows that the shirt belongs to the man.

To show ownership, add an apostrophe and a /s/ to the noun. Notice that possessive nouns can be common (dog, book, man) or proper (Mary).

To make most nouns plural you add a /s/ only, but  possessive nouns must have an apostrophe and a /s/. That's how the reader will know that the noun is  possessive. Do not add apostrophes to nouns that are not possessive.
