Answer 3

Okay, but what exactly is an antecedent? Still have a hard time to grasp that.

Answer 4

In grammar, an antecedent is an expression (word, phrase, clause, etc.) that gives its meaning to a pro-form (pronoun, pro-verb, pro-adverb, etc.). A proform takes its meaning from its antecedent, e.g. Susan arrived late because traffic held her up.
