6. Pronouns

Pronouns are words used in the place of nouns.

Example:

Rita is going to school. Rita will come back by afternoon.

Here, the noun 'Rita' is used repeatedly.

Hence, we substitute it with the pronoun 'she' in the second sentence.

Rita is going to school. She will come back by afternoon.

Thus, pronouns:

1. Convey the same meaning as the original noun.
2. Help in shortening the sentence by avoiding repetition. 

There are 10 different kinds of Pronouns.
