Definition: Ante (not anti) means before. The root cedere means to go. The antecedent goes before the pronoun. It is the noun that the pronoun replaces. A pronoun must match, or agree, with its antecedent in number, person, and gender.
Hint:You can be sure a noun is the antecedent if you can use that noun in place of the pronoun.
