Relative Clauses

Relative clauses give more information about a person, thing, or place without starting a new sentence. They usually begin with words like who, which, or where.

Explanation

What Are Relative Clauses?

Relative clauses help connect ideas or add interesting details without starting a new sentence.

Example: The girl who lives next door is my friend.

Relative Pronouns

We use relative pronouns to join sentences together.

Refers to

Relative Pronoun

Example

People

who / that

I met a man who plays the guitar.

Things

which / that

I have a bike that is very fast.

Possession

whose

She is the girl whose dog is lost.

Places

where

That’s the café where we met.

Two Types of Relative Clauses

Defining Relative Clause

Gives important information about the noun. We do not use commas.

Example: The students who study hard pass the test.
(If we remove the clause, the meaning changes.)

Non-defining Relative Clause

Gives extra information that is not necessary to understand the main idea. We use commas around the clause.

Example: My uncle, who lives in Canada, is visiting us next month.
(If we remove the clause, the sentence still makes sense.)

Relative Pronouns in Action

  • When the pronoun is the subject

The dog that barks every night is mine.
The woman who teaches English is very kind.

  • When the pronoun is the object

We can often leave it out.
The book (that) I read was amazing.
The man (who) you saw is my boss.

Using “Whose” for possession

We use whose to show that something belongs to someone.
Examples:
The boy whose phone rang was embarrassed.
That’s the artist whose paintings are famous.

Prepositions in Relative Clauses

Some verbs need prepositions (like to, for, with). In relative clauses, the preposition often comes at the end.
Examples:
The town (that) I was born in is very old.
The people (who) I work with are great.
The chair (that) she is sitting on is broken.
