A pronoun is a word that is used in the place of a noun. A relative pronoun is one which is used to refer to nouns mentioned previously, whether they are people, places, things, animals or ideas. Relative pronouns can be used to join two sentences or to connect a clause/phrase to a noun or pronoun. Therefore, a relative clause is a part of a sentence that has a verb in it and is joined to the rest of the sentence with relative pronouns.
The most common relative pronouns are who, whom, whose, which and that.
