A free CEFR A2 grammar lesson from Virtuous English Academy · 4 key rules · 10-question check · 60 exercises

Relative clauses add information to a noun using who (people), which (things) and where (places). This lesson shows how to join two ideas into one clear sentence.

Written and reviewed by Vugar Novruzov, Founder & Publisher · How we write our lessons

A main clause, the woman is a doctor, with a dashed gap after the subject and the clause who lives next door arriving in it from below, an arrow running from the relative pronoun back to the woman. Underneath, two worked columns: a defining clause written without commas, which cannot be removed, and a non-defining clause fenced by two commas, which can be lifted out leaving my sister is a doctor.
Start with the top half and leave the commas until later. A relative clause is a whole second sentence posted into a gap in the first, and the pronoun is the thread tying it back to the noun in front of it — who for people, which for things, where for places. Every question in this set is that one move.

How to form Relative Clauses

Choose the pronoun according to what kind of noun it refers back to.
PronounRefers toExample
whopeopleThe woman who called is my aunt.
whichthings and animalsThe film which won the prize was Italian.
thatpeople or things (defining only)The car that broke down is mine.
whereplacesThe town where I grew up is small.
whentimesThe year when we met was 2018.
whosepossessionThe man whose dog barks lives here.

Relative Clauses explained

Relative clauses are clauses with who, which or where that add information about a noun without starting a new sentence. Instead of The man lives next door. He is a doctor, you say The man who lives next door is a doctor. This is how English builds longer, more connected sentences, and it is a genuine step up from the short sentences of A1.

The relative pronoun you choose depends on what you are describing. Who is for people, which is for things and animals, that works for both, where is for places, when is for times, and whose shows possession. Getting the right one is mostly a matter of asking what kind of noun came before it.

The relative pronoun always comes immediately after the noun it describes, and it replaces the subject or object of the clause. This means you never repeat the noun or add another pronoun: The book which I bought it is wrong, because which already stands for the book.

Relative Clauses: the key rules

  1. Who refers to people, which to things and animals, where to places.

    the woman who lives upstairs; the film which won; the café where we met

  2. That can replace who or which in defining clauses.

    the book that changed my life

  3. The relative pronoun replaces the repeated noun — don't say it twice.

    the man who called (not: the man who he called)

  4. Defining clauses add essential information and take no commas.

    Students who arrive late miss the quiz.

When to use Relative Clauses

Defining vs. non-defining clauses

The commas are not decoration — they change the meaning of the sentence.

Defining — no commas

Essential information identifying which one. That can replace who or which. Cannot be removed.

The students who passed will get certificates. (only those students)

Non-defining — with commas

Extra information about something already identified. That is not allowed. Can be removed.

The students, who passed, will get certificates. (all of them passed)

Relative Clauses in example sentences

Relative Clauses in a real conversation

In this conversation, several relative clauses could drop the relative pronoun. See if you can spot which ones.

Eva:Do you know the man who runs the bakery?

Jan:The one whose son plays in the band? Yes.

Eva:He sold me a cake that was completely stale.

Jan:That's the shop where I stopped going last year.

Eva:My sister, who lives nearby, said the same thing.

Jan:The bread I bought there was fine, but that was months ago.

Practise Relative Clauses today

Combining sentences is the most useful exercise here, because it mirrors what the structure is for.

  1. Combine these pairs: I met a woman. She works in publishing. / This is the house. I grew up in it.
  2. Write six sentences about people you know, each with a who clause.
  3. Add commas where the clause is non-defining and explain why.
  4. Correct these: The book which I read it was good. — The man which called. — My friend who lives in Rome, is a chef.

Relative Clauses: frequently asked questions

When can I leave out the relative pronoun?

You can omit it when it is the object of the relative clause and the clause is defining: The film I saw was excellent, where which or that has been dropped. You cannot omit it when it is the subject — The man who called is wrong as The man called, which means something else. A quick test: if a noun or pronoun follows immediately, the relative pronoun is the object and can go.

What is the difference between who and that?

Both work for people in defining clauses, and both are correct: The man who called and The man that called. Who is generally preferred for people in careful writing, and some readers dislike that for humans. In non-defining clauses with commas, only who is possible — My boss, that lives nearby is wrong. Using who for people and which for things is always safe.

Why do the commas matter so much?

The commas matter because they change what the sentence claims. My sister who lives in Rome is a lawyer implies you have more than one sister and are identifying which. My sister, who lives in Rome, is a lawyer implies you have one sister and are adding a detail. The comma converts essential identification into optional extra information, so it genuinely alters the meaning.

Can I use where for anything other than a place?

In careful English, no — where refers to physical or conceptual locations: the town where I live, a situation where nobody wins. For times use when, and for possession use whose. You will hear where used loosely in speech, but in writing keeping the three separate makes your sentences noticeably clearer and is expected in exams.
