1. Relative clauses

2. Relative clauses begin with a question word (who, which, where, …) and are used to modify a noun that appears in the main clause.
They can:
a) tell us which person or thing is meant:
Do you know the people who live next door?
There’s a TV series tonight that I want to see.
b) give more information about the person or thing:
This is my brother, who wants to meet you.
My new computer, which I bought online, is really fast.
There are several grammatical and stylistic differences between the two kinds of relative clauses.
