We use relative clauses to define the thing we are talking about. Take a look at the lesson and test yourself with the quiz to develop your knowledge on relative clauses.
We use relative clauses to give some extra information about the related object/person.
There are 2 types of relative clauses, non-defining and defining relative clauses. The defining relative clauses gives us very important information about the thing we are talking about.

We usually use who, which, that, when, where or whose to start the relative clause.

Leaving out a clause
We often leave out the relative pronoun when using a relative clause.
