• Defining relative clauses:
 These clauses tell us which person or
thing the speaker means.
 Ex: The woman who lives next door is

a journalist.
• Non-defining relative clauses:
 These clauses give more information
about a person or thing already
identified.
 When we write these clause, we use
“comma (,)” at the beginning and at
the end of the clauses.
 In non-defining relative clauses we
cannot use “that”. We cannot also
leave out “which or who”.
 Non-defining relative clauses are used
in sentences containing proper
name/noun; possessive adjectives (my,
his, her, our, their, its) and
demonstrative pronouns (this, that,
these, those).

: John, who speaks French and
Italia, works as a tour guide.
