What I need is…: cleft sentences for focus

Use what-clauses, it-clefts and all / the reason / the thing to put the focus where you want it

What you'll be able to do

Highlight the key point in presentations, meetings and writing: correct a misunderstanding, stress what matters most, or say what you really mean.

What-clefts

What + clause + be + focus:

  • What I need is a long holiday.focus on a long holiday
  • What surprised me was how calm she stayed.focus on her calm

It-clefts

It + be + focus + who / that + rest: often to correct someone.

  • It was Ana who found the error, not Tom.focus on Ana
  • It's the cost that worries me.focus on the cost

For people, both who and that are correct: It was Ana who / that found it.

Other patterns

  • All I want is a quiet weekend.only this
  • The reason I left is that the hours were too long.focus on the reason
  • The thing is, we don't have enough time.introducing the main problem (spoken)

Common mistakes

  • That I need is a holiday. → What I need is a holiday.
  • What I need it is a holiday. No extra it: What I need is…
  • The reason is because… In careful English: The reason is that…
