A relative pronoun makes a connection between an antecedent  an a subordinate clause that gives information about the  antecedent.   The relative pronouns are: who, whomâ¦, whose, which, that.    Examples:   The teacher who assigned the work should answer your  questions.
Relative pronouns introduce subordinate clauses functioning as adjectives. Use commas to set off nonrestrictive subordinate clauses, and do not use commas to set off restrictive clauses. The choice of relative pronouns is determined by the way the pronoun is used and the noun or pronoun to which it refers. Who, which, and that take verbs that agree with their antecedents.
