Read the following sentences.

• The bag of Jasmine is on the chair.

• The car of my sister-in-law was stolen.

These sentences show possession in a rather long way. Now, read the following:

• Jasmine's bag is on the chair.

• My sister-in-law's car was stolen.

Jasmine's and sister-in-law's are possessive nouns. A possessive noun shows possession.

It changes its form to show that it owns or is closely related to something else.
