what is relative pronoun

A relative pronoun is a type of pronoun that introduces a dependent clause and connects it to an independent clause. The dependent clause introduced by a relative pronoun provides additional information about the noun or pronoun mentioned in the independent clause. The most common relative pronouns in English are who, whom, whose, which, that, whoever, and whomever. Relative pronouns can function as the subject, object, or possessive of the dependent clause they introduce. The use of a relative pronoun depends on the type of noun being described. Relative clauses introduced by relative pronouns are also sometimes referred to as adjective clauses because they describe the subject of the independent clause. It is important to note that not all languages have relative pronouns, and even within languages that have them, not all relative clauses contain relative pronouns.
