Nouns form the possessive in two ways: (1) they become the object of the preposition of, or (2) they add the ending -’s (apostrophe plus -s). Look at these examples:
|the roar of a lion||a lion’s roar|
|the color of the book||the book’s color|
|the children of Mrs. Diaz||Mrs. Diaz’s children|
|the prey of the wolves||the wolves’ prey|
The possessive is used to show to whom or to what something belongs:
- This is Ginny’s car.
- The kittens of an alley cat have a hard life.
