A possessive noun shows who or what owns something. A possessive noun can either be singular or plural. A singular possessive noun shows that one person, place, or thing has or owns something. To make a singular noun show possession, add an apostrophe and s (‘s).
Example: the feathers of the chick – the chick’s feathers the hat that belongs to the man – the man’s hat Other examples: the child’s toy
The fish’s fins
The horse’s tail
Using possessive nouns is shorter and better than other ways of showing possession.
LONGER: The dog belonging to Papa is barking.
BETTER: Papa’s dog is barking.
