Relative clauses
|
||
Defining relative clauses are used to specify which person or
thing we mean. We don't put commas between the noun and a defining relative
clause.
Who or that are used for people. Which or that are used for things. |

five languages.

|

she had bought.

||
Non-defining relative clauses (extra information clauses) are used to
add extra information to a sentence. We put commas between the noun and a
non-defining relative clause.
Who is used for people. Which is used for things. That cannot be used. |
The area, which has very high unemployment, is in the north of the country. |
