Relative clauses are used to provide extra information about a person, thing, or place without starting a new sentence. There are different relative pronouns used depending on what is being referred to: who is used for people, which is used for things and animals, and where is used for places. Relative clauses with who or that can be used when referring to people as the subject. They can also be used to provide additional information about things, animals, and places.
