An apostrophe is a punctuation mark that is used for two purposes.
1.To show possession
We use an apostrophe to show possession when we either want to show that something belongs to someone, or want to describe a relation between two people.
This is Gino’s hat. That is Mary’s sister. The following rules must be kept in mind when using an apostrophe to show possession.
|An apostrophe comes before ‘S’ if the noun is singular.||This car’s design seems modern.|
|An apostrophe comes after the ‘S’ if the noun is plural.||The girls’ dresses look nice.|
|An apostrophe comes before the ’S’ if the noun is an irregular plural.||Let’s go to the children’s nursery.|
