Defining and non defining relative clauses
Defining relative clauses
Clauses that contain key information. The information contained in the relative clause is essential and cannot be left out.
We can use “that” to introduce a defining relative clause, but also “who”, “which”, “whose”, “whom”.
This clause helps us define what we are talking about.
No commas are used in defining relative clauses.
There the people who/that will be moving in next door.
You should give this to someone who/that is in need.
You will see some areas which/that have been affected.
They’re the patients that/who are showing the symptoms.
Non defining relative clauses
Clauses that describe or explain further but doesn’t contain key information.
Non-defining relative clauses are used to give further information about the person or thing mentioned in the main clause. It is not important information. We do not need it to understand whom or what is being referred to.
We always use a relative pronoun (who, which, whose or whom) to introduce a non-defining relative clause.
We don’t use “that” to introduce a non-defining relative clause.
In writing, we use commas around non-defining relative clauses.
In spoken English, we often pause at the beginning and end of the clause.
