What is the purpose of pronouns in the English language?

The purpose of pronouns in the English language is to replace nouns. This function serves to avoid repetition and streamline communication. For instance, instead of saying "Jessica went to Jessica's car," one can say "Jessica went to her car," where "her" is the pronoun that replaces the noun "Jessica." Pronouns help in making sentences less cumbersome and easier to follow, enhancing clarity and fluidity in speech and writing.

By substituting various types of nouns (such as proper nouns, common nouns, and even noun phrases), pronouns maintain the coherence of discourse while allowing speakers and writers to keep the focus on the action or description rather than the subjects themselves. This ability is fundamental in both spoken and written English, making pronouns an essential component of the language.
