Relative clauses

Relative clauses give us information about the person or the thing mentioned. 

Defining relative clauses:

Defining relative clauses give us essential information.

We usually use a relative pronoun to start a defining relative clause: who, which, that, when, where or whose.

The relative pronoun in some defining relative clauses can be omitted.

        The man who is wearing a leather jacket is very rich.(ü)   

        The man wearing a leather jacket is very rich. (ü) 

Non-defining relative clauses:

Non-defining relative clauses give more detail/ (extra/additional) information about what is being talked about.

Non-defining relative clauses are enclosed between two commas unless completing the sentence.

In non-defining relative clauses, the relative pronoun is never omitted.

      The architect of the tower was Ahmad Ben Baso, who began work in 1184 CE. (ü) 

      The architect of the tower was Ahmad Ben Baso, began work in 1184 CE.(x)
