Cleft sentences

It was … that…, It wasn't until…, What I need is…, All I want is…

Finn says

Cleft sentences help you emphasise the most important part of a sentence. You split one sentence into two parts to put the focus where you want it.

It-clefts

It + is / was + the focus + that / who + the rest.

A person or thing
It was + person + who / that…
Tom broke the window. → It was Tom who broke the window.
A time or place
It was + time / place + that…
It was in 2010 that we first met.

Not until / only when

Very common in Part 4. They stress the moment something happened.

Not until
It wasn't until + time / clause + that…
She didn't arrive until midnight. → It wasn't until midnight that she arrived.
Only when / after / later
It was only when / after + clause + that…
I realised when I got home. → It was only when I got home that I realised.

What-clefts and similar

What + clause + is / was + the focus.

What
What + subject + verb + is…
I need a holiday. → What I need is a holiday.
An action
What + subject + did + was (to) + infinitive
She called the police. → What she did was (to) call the police.
All / The thing / The reason
All I want is… / The reason why… is…
All I want is some peace and quiet.

How it comes up in Part 4

In Part 4 you complete the second sentence with the key word, so that it means the same as the first one (3–6 words).

I only understood the problem after I had spoken to the manager.
UNTIL
It wasn't until I had spoken to the manager that I understood the problem.

It wasn't until + clause + that. Note: 'wasn't' counts as two words.

The noise from the street really annoys me.
WHAT
What really annoys me is the noise from the street.

What + clause + is + focus.

Jane, not Mark, found the keys.
WHO
It was Jane who found the keys.

It was + person + who: the focus is on Jane.

Common mistakes

  • ✗ What I need it is a holiday.✓ What I need is a holiday.No 'it' before 'is'.
  • ✗ It was until midnight that she arrived.✓ It wasn't until midnight that she arrived.'Not until' needs the negative.
  • ✗ It were my parents who helped me.✓ It was my parents who helped me.Always 'it is' / 'it was', even with a plural focus.

Finn's exam tip

If the key word is WHAT, UNTIL, ONLY, WHO or ALL, think about emphasis. The meaning of the sentence doesn't change – only the focus does.

Quick check

Complete the second sentence so that it means the same as the first. Use the key word and write 3–6 words.
