What is pronoun antecedent agreement?

Pronoun-antecedent agreement is a grammatical concept that ensures that pronouns and their antecedents (the Words they refer to) match in number and gender. This agreement is crucial for clarity and coherence in writing, as it helps readers understand the relationships between pronouns and the nouns they represent. When there is a lack of agreement, it can lead to confusion or ambiguity in a sentence.
