Ambiguous Antecedents
An ambiguous antecedent happens when a pronoun like he, she, or they could logically point back to more than one noun in the sentence, so the reader can't tell who did what. The fix is to replace the pronoun with the actual noun it should mean.
Take 'When Rosa met Ana, she was nervous.' There are two women in that sentence, and 'she' could be either one. Your ear doesn't flag this as broken the way a subject-verb mismatch does, because the grammar is fine. The sentence is a complete, correctly built sentence that simply fails to say what it needs to say. That's the trap: ambiguity is a meaning problem wearing a grammar costume, so you have to read for who-did-what, not just for matching verb endings.
Picture two arrows leaving the pronoun, one pointing at each candidate noun. If both arrows land on a noun that fits logically and grammatically, the sentence is ambiguous, and no amount of rereading settles it, because the sentence itself refuses to choose. Word order doesn't decide it either. In 'The lawyer told the client that he had made an error,' 'he' sits closer to 'client' than to 'lawyer,' but closeness isn't proof; either one could plausibly have made the error. The only real fix is to delete the pronoun and name the noun: 'the lawyer told the client that the lawyer had made an error,' or recast so one candidate drops out entirely, as in 'the lawyer admitted the error to the client.'
This sits right next to misplaced modifiers in the same family of problems, because both are about a word losing track of which noun it belongs to. A modifier can drift and attach to the wrong noun the same way a pronoun can point at the wrong noun; in both cases the repair is the same instinct, trace the connection, then rewrite so only one noun is available to receive it.
