Pronoun is that parts of speech which acts as a pillar to the foundation laid by the Noun that is, it represents a Noun in a sentence. One must be wondering, when we have a noun in the sentence then why do we require a pronoun. Well, it’s simple! In a sentence like ‘Tom had Tom’s breakfast with Tom’s friends and went to visit Tom’s parents’ using Tom for multiple times is kinda repetitive hence, we use pronoun in such situations to avoid this repetition.
Eg: Tom had his breakfast with his friends and when to visit his parents.
