Relative Clauses

video

As the name suggests, these clauses give essential information to define or identify the person or thing we are talking about. Obviously, this is only necessary if there is more than one person or thing involved.

Example

• Dogs that like cats are very unusual.

In this sentence we understand that there are many dogs, but it is clear that we are only talking about the ones that like cats.

Punctuation

• Commas are not used in defining relative clauses.

Relative pronouns

The following relative pronouns are used in defining relative clauses:

	Person	Thing	Place	Time	Reason
Subject	who/that	which/that
Object	who/whom/that/	which/that/	where	when	why
Possessive	whose	whose

Notes:

1. The relative pronoun stands in place of a noun.

This noun usually appears earlier in the sentence:

The woman	who/that	spoke at the meeting	was very knowledgeable.
Noun, subject of main clause	relative pronoun referring to 'the woman', subject of 'spoke'	verb + rest of relative clause	verb + rest of main clause

1. Who, whom and which can be replaced by that. This is very common in spoken English.
2. The relative pronoun can be omitted when it is the object of the clause

The woman	that	the man loved	was living in New York.
Noun, subject of main clause	relative pronoun, referring to 'the woman', object of 'loved'	verb + rest of relative clause	verb + rest of main clause.

(You can usually decide whether a relative pronoun is an object because it is normally followed by another subject + verb.)

4. Whose is used for things as well as for people.

Example

• Dogs that like cats are very unusual.

In this sentence we understand that there are many dogs, but it is clear that we are only talking about the ones that like cats.

Punctuation

• Commas are not used in defining relative clauses.
