Cleft sentences use a two clause construction and usually start with the empty introductory subjects of what or it.
Cleft is an adjective that means to split or divide something into two parts.
But in grammar, we use this division to add emphasis to the first clause in a sentence. There are many different cleft constructions in English, but the most common are it-clefts and wh-clefts.
You may not use these often in your writing. Yet it is worth understanding how to correctly add more emphasis to certain sentences when the need arises.
How to construct cleft sentences
As its name implies, there are always two parts (clauses) to a sentence.
The two basic constructions of cleft sentences use it or what and the verb to be.
It + Be + That Clause
What Clause + Be + Clause
Let’s take two simple declarative sentences to show you how each form works.
A familiar face on the book cover attracted my attention.
It-cleft: It was a familiar face on the book cover that attracted my attention.
Wh-cleft: What attracted my attention was a familiar face on the book cover.
In the first cleft, the emphasis is placed on a familiar face. In the second, it is on the attraction.
I read the book, but the ending of the story was disappointing.
It-cleft: It was the ending of the story that was disappointing.
Wh-cleft: What disappointed me was the ending of the story.
In the first cleft, the emphasis is placed on the ending. In the second, it is on the disappointment.
With these two forms, you can change any simple sentence and move the most important element to the first clause.
Moving the emphasis
You can take almost any sentence and use a cleft form to move the emphasis to the first clause of a sentence.
Here’s an example of how you can rewrite a sentence in four ways.
Jane went to Rome with her mother last summer.
Emphasis on the subject.
It was Jane who went to Rome with her mother last summer.
Emphasis on the direct object.
It was with her mother that Jane went to Rome last summer.
Emphasis on the adverb of time.
It was last summer that Jane went to Rome with her mother.
Emphasis on the indirect object.
It was to Rome that Jane went with her mother last summer.
Pseudo cleft sentences
Psuedo clefts use the wh-cleft form but don’t have a full second clause.
They are commonly used with verbs such as need, want, like, or dislike.
What you need is a holiday.
What I want is a break from work.
What I like is his smile.
What I dislike is working on the weekend.
You can also add more emphasis by using the auxiliary do/did/doing.
What people do is their business.
What Peter did was unforgivable.
What they are doing to the riverfront is awful.
Other forms of clefts
English is rich in different cleft structures.
We use them from time to time but may not recognize or know the name of the grammatical form.
Here’s a quick list of some of the more common cleft forms complete with example sentences.
Where, when, why, how-clefts
In place of what, you can also create clefts with other wh-words and how.
However, when you use why, how, or whom, there is a possibility that the sentence might sound a little awkward.
She enjoys going to the cinema the most.
Where she enjoys going to the most is the cinema.
She likes to go to the cinema on Fridays.
When she likes to go to the cinema is on Fridays.
She has an annual pass for the cinema.
Why she goes to the cinema is because she has an annual pass.
She paid for her pass with her credit card.
How she paid for her pass was with her credit card.
The only wh-word that can’t be used is whose.
When you use this form, the word all makes the first clause far more important.
He wanted to buy a vintage car.
All he wanted to do was buy a vintage car.
Mona complains about everything.
All Mona does is complain.
An inferential cleft can help clarify something when it might be wrongly assumed.
The structure is usually two consecutive it-that sentences.
The first is negative, but then the second clause makes the clarification.
It’s not that I’m mean with money. It’s that I choose to spend it wisely.
You can also add just to the clarifying clause.
It’s not as if he doesn’t want to get married. It’s just that he would like to save a bit more money first.
In this cleft form, it reverses the standard form and moves the what clause to the second clause in a sentence.
He wanted to buy a new Macbook Air.
A new Macbook Air is what he wanted to buy.
He wanted to find a new job.
A new job is what he wanted to find.
When you use this form, it takes the empty subject word, there to start the first clause.
It most commonly emphasizes the object of a simple sentence.
Mary wants to buy a new car.
There‘s a new car that Mary wants to buy.
I want to watch the new James Bond movie.
There‘s a new James Bond movie that I want to watch.
In this form, you can create a reason for an action.
He wants to leave home to be independent.
If he wants to leave home, it’s because he wants to be independent.
Jane uses social media to become famous.
If Jane uses social media, it’s because she wants to become famous.
Similar to other grammar forms such as inversion, using cleft sentences in your writing can help you add a little more variety.
But you should use them in moderation and only when it’s necessary to create stronger emphasis.
A simple declarative sentence is almost always easier to read than a complex cleft sentence.
However, when you want to add extra weight to one particular part of a sentence, you have the grammar tools to do it.
