Relative Pronouns

A relative clause is a phrase that adds information to a sentence. All relative clauses describe a noun, and they begin with one of these relative pronouns or relative adverbs.

who (to describe people – subject)

whom (to describe people – object)

whose (to describe possession)

that (to describe things – defining relative clauses)

which (to describe things – non-defining relative clauses)

You can see if a relative clause is defining or non-defining by removing it from the sentence.

If you remove a non-defining relative clause, the sentence still has the same meaning. - My brother, who lives in California, is an engineer.

If you remove a defining relative clause, the sentence has a different meaning or is incomplete. - That’s the student who failed English class three times
