Look at this example sentence:
The woman who lives next door is a doctor. (the relative clause is highlighted in the sentence.)
A clause is a part of a sentence. A relative clause tells us which person or thing (or what kind of person or thing) the speaker means:
Use of “Who” in Sentence
The woman who lives next door . . . (‘who lives next door’ tells us which woman)
People who live in the country . . . (‘who live in the country’ tells us what kind of people)
We use who in a relative clause when we are talking about people (not things):
the woman – she lives next door – is a doctor
The woman who lives next door is a doctor.
we know a lot of people – they live in the country
We know a lot of people who live in the country.
Relative Clause (Who) Examples
An architect is someone who designs buildings.
What was the name of the person who phoned you?
Anyone who wants to apply for the job must do so by Friday.
You can also use that (instead of who), but you can’t use which for people:
The woman that lives next door is a doctor. (not the woman which)
When we are talking about things, we use that or which (not who) in a relative clause:
where is the cheese? – it is in the fridge
Where is the cheese {that/which} was in the fridge?
Relative Clause (Which) Examples
I don’t like stories that have unhappy endings. (or stories which have . . .)
Barbara works for a company that makes furniture. (or a company which makes furniture)
The machine that broke down is working again now. (or The machine which broke down)
Remember that in relative clauses we use who/that/which, not he/she/they/it:
I’ve never spoken to the woman who lives next door. (not the woman she lives)
