A pronoun is a part of speech that is used to replace a noun or noun phrase in a sentence. It is used to avoid repetition and make sentences less cumbersome. Pronouns stand in for nouns to refer to people, places, things, or ideas without having to repeat the noun itself.
Pronouns help to maintain sentence flow, clarity, and efficiency in language by referring back to nouns previously mentioned or understood within the context.
