Emma: Did you see the news about the new policy at work?

Mark: Yes, I did! It was the HR manager who sent the email this morning.

Emma: Exactly. What surprised me is that they didn’t consult us first.

Mark: I know. We’ve been working so hard lately. What we need is a break, not more rules.

Emma: I agree. My supervisor said we just have to accept it. But it feels unfair.

Mark: Well, it was in the meeting last week that they hinted at some changes.

Emma: Yes, but they made it sound like a minor update. What they actually did was completely rewrite the guidelines.

Mark: It’s going to cause a lot of frustration among the team.

Emma: Definitely. It is the lack of communication that bothers me the most.

Now the rules behind what you just saw — explained simply, with examples. Underlined words open a short definition — hover on desktop, tap on a phone.

When we want to focus on a specific part of a sentence, we can use a cleft sentence. “Cleft” means divided. We divide a simple sentence into two clauses to give extra focus to one part of it.

It-cleft sentences

We use It is / was + emphasized part + that / who / which + rest of the sentence to emphasize nouns, pronouns, or prepositional phrases.

format_quoteEXAMPLE

Normal: I lost my keys in the park.

Emphasis on the object: It was my keys that I lost in the park.

Emphasis on the place: It was in the park that I lost my keys.

lightbulbTIP

We usually use “that” in cleft sentences, but “who” is also common when emphasizing a person.

What-cleft sentences

We use What + clause + is / was + emphasized part to emphasize an action or an entire clause. These sentences often use the verb do.

format_quoteEXAMPLE

Normal: I need a long holiday.

Emphasis: What I need is a long holiday.

Normal: He ignored the warning.

Emphasis: What he did was ignore the warning.

warningWARNING

Don’t forget the verb “to be” (is/was) after the what clause. Incorrect: What I want a coffee. Correct: What I want is a coffee.

Emphasizing emotions and reactions

Cleft sentences are very useful to express strong feelings or describe how an outcome surprised you.

format_quoteEXAMPLE

What surprised me most was his reaction.

It was her resilience that inspired us all.

boltQUICK REVIEW
  • It-cleft: It is/was + [focus] + that… (e.g., It was the weather that ruined the trip.)
  • What-cleft: What [clause] + is/was + [focus] (e.g., What we need is more time.)
  • Use It-clefts mainly for nouns and prepositional phrases.
  • Use What-clefts mainly for actions (using do) and whole clauses.
