Repeating full noun phrases quickly becomes clumsy. A pronoun is a word that substitutes for a noun or noun phrase, allowing reference to continue without constant repetition.

Personal, demonstrative, possessive, reflexive, interrogative, and relative pronouns serve different discourse jobs. Pronoun systems encode person, number, gender, politeness, and case to varying degrees. Some languages allow or prefer zero pronouns when reference is clear.

Pronoun resolution is essential for coherence and for computational language understanding. Social debates around gendered pronouns show how tightly these small words bind to identity. Children acquire basic personal pronouns early as they navigate participant roles in conversation.
