Бесплатный урок английского с Notes – Грамматика – Defining and Non-Defining Relative Clauses (B2-C1)

Use it right!

1. We can use that instead of who and which when talking about people or things in defining relative clauses.
   
   I have a friend who/that knows how to speak Japanese.
   This is the car which/that I told you about.

2. Relative pronoun whom is used when the person is the object of the action, but not its subject. In spoken English who is also acceptable instead of whom.
   
   This is the person whom I told you about.
   Where is the officer whom we need to give our complaints to?
