What is the primary function of pronouns in a sentence?

The primary function of pronouns in a sentence is to take the place of nouns. This helps to avoid repetition and provides a more fluid structure when communicating. For instance, instead of saying "Janet went to the store, and Janet bought some milk," one can say "Janet went to the store, and she bought some milk," where "she" is a pronoun that replaces "Janet." This substitution enhances clarity and conciseness in writing and speech.

Using pronouns allows speakers and writers to reference individuals or objects without continuously repeating their names. This is particularly important for maintaining coherence and preventing redundancy in communication.
