We use relative pronouns to introduce relative clauses. The relative pronouns are:
- that
- which
- who
- whom
- whose
As in these examples:
- I know the boy who found my dog.
(relative pronoun/who – relative clause/found my dog) - My new dog, which I bought last year, loves chicken.
(relative pronoun/which – relative clause/I bought last year)
