Another kind of pronoun is the relative pronoun.

Relative pronouns are used to introduce subordinate or dependent clauses. A relative pronoun connects a subordinate clause or an independent clause to its antecedent in the sentence.

A clause is a group of words with a subject and a verb. An independent clause can stand on its own and has a complete thought.

However, a dependent clause does not convey a complete thought and needs other words to complete the meaning of the sentence.

The book The Little Prince teaches its readers lessons that they will always cherish.

The book The Little Prince teaches its readers lessons - main or independent clause

that they will always cherish - subordinate or dependent clause

When referring to people the relative pronouns who, whom, whoever, and whomever are used.

This is the boy who introduced me in class.

Who introduced me in class is the clause and who is the relative pronoun that connects boy, its antecedent, to the phrase introduced me in class.

When referring to a place, thing, or idea, use the relative pronouns which and that.

The flower shop that you are looking for is two blocks away.

A clause introduced by a relative pronoun may function as an adjective or a noun.
