Relative Clauses

who · which · that · where · whose

What are relative clauses?

Relative clauses give more information about a noun. They connect two ideas in one sentence using a relative pronoun.

Two sentences
I have a friend. My friend lives in London.
One with relative
I have a friend who lives in London.
Relative pronouns
who (people) · which (things) · that (both) · where (places) · whose (possession)

who — for people

Replaces he/she/they referring to a person

noun + who + verb    the student who passed

which — for things

Replaces it/they referring to a thing

noun + which + verb    the book which I read

that — for people and things

Informal alternative to who/which

for things

very common spoken
"that" is the most frequent relative pronoun in everyday speech
After superlatives and all/the only/the first/the last, always use "that": the best film that I've seen.

where — for places · whose — for possession

where
the school where I studied · the town where I grew up
whose
the student whose essay won (= the student's essay)
