Adjective clauses with and without commas
Defining adjective clauses (without commas)
Sometimes the adjective clause is necessary to tell us which thing / person we are talking about. In this case, there are no commas.- That's the man who offered me a lift home.
- I've just finished the book you gave me for Christmas.
In both cases, we need the adjective clause to know which man / book we are talking about.
Non-defining adjective clauses (with commas)
Sometimes the adjective clause gives us extra information. It is not necessary to tell us which thing / person we are talking about. In this case, there are commas before and after the clause.
- Christmas Day, which is on a Thursday this year, is always a public holiday.
- He gave me a photograph, which I keep in my wallet.
Some rules:
* You cannot use that.
- Christmas Day, t
* You cannot leave out the relative pronoun.
- He gave me a photograph, which I keep in my wallet.
* Prepositions can go either at the beginning or at the end of the clause.
- His greatest hobby was motor racing, on which he spent a great deal of money.
