What is a relative clause?
A relative clause adds information about a noun, so you can say two things in one sentence. It starts with who, which, that or where.
Why use it
- To say which person or thing you mean.
- To sound more natural than many short sentences.
Pattern
noun + who / which / that + rest of the clause
Examples
- The woman **who** lives next door is a nurse. — who → a person
- The bag **that** I bought is red. — that → person or thing
The rule
Join information about a noun: who for people, which for things, that for both. where for places.
Two sentences → one: I have a friend. She lives in Rome. → I have a friend who lives in Rome.
Common mistakes
- Not:
the man which called— But: the man who called - Not:
the book who I read— But: the book that / which I read
