This document discusses pronouns and antecedents. It defines a pronoun as a word that replaces a previously mentioned noun, and an antecedent as the original noun being replaced by the pronoun. It then provides examples of pronouns and antecedents. Finally, it discusses three potential problems with pronouns: missing or faraway antecedents that cause confusion, anticipatory antecedents where the reader must finish the sentence to understand the referent, and ambiguous antecedents where it is unclear which previous noun is being referenced.
