What Is a Cleft Sentence?

Clear and expressive writing in English will mainly apply the active voice, in which a lead subject performs an action by means of the verb. In developing style and voice, writers will become proficient in facets such as mood and tone and nimble variation as well.

At times we also may find ourselves wanting or needing to emphasize a sentence element other than the main subject and verb. For example, we use the passive voice when we wish to stress the object:

Active: Quasimodo rang the tower bell. (emphasis subject)

Passive: The tower bell was rung by Quasimodo. (emphasis object)

Another method for shifting grammatical weight is the cleft sentence, which is a complex sentence that moves a component from its normal position into a different clause to draw greater attention to it.

Cleft Sentences: It

The “it” cleft sentence is perhaps the most common. You’ll recognize it by its structure:

introductory word > form of to be > emphasized element > defining relative clause

Standard sentence: Tamil solved the complex equation this morning.

Cleft sentence: It was this morning that Tamil solved the complex equation.

introductory word It
form of to be was
emphasized element this morning
defining relative clause that Tamil solved the complex equation

We might use this construction in a context where we know that Tamil solved the complex equation (understood information), but we are not aware of when he did (new information). The cleft sentence links what is understood to what is new while drawing extra attention to the new information.

The same “it” cleft sentence can be written in other ways to cast different emphasis:

Cleft sentence: It was the complex equation that Tamil solved this morning.
Understood: Tamil solved something this morning.
New: It was the complex equation.

Cleft sentence: It was Tamil who solved the complex equation this morning.
Understood: Someone solved the complex equation this morning.
New: It was Tamil.

Cleft Sentences: Wh-words and How

In addition to the common “it” cleft sentence, you’ll recognize others that start with words such as who, what, when, where, and why as well as how.

Standard: We need to find out who put salt instead of sugar in the coffee.
Cleft: Who put salt instead of sugar in the coffee is what we need to find out.
Cleft Understood: We need to find out something.
Cleft New: Someone put salt instead of sugar in the coffee; we don’t know who did it.

Standard: No one knows where she goes.
Cleft: Where she goes is what no one knows.
Cleft Understood: There’s something no one knows.
Cleft New: Something = where she goes

Standard: They don’t understand how to change the tire.
Cleft: How to change the tire is what they don’t understand.
Cleft Understood: The tire is broken or flat; they don’t understand something.
Cleft New: Something = how to change the tire

Note that these cleft constructions also can be inverted to flip the emphasis:

What we need to find out is who put salt instead of sugar in the coffee.
What no one knows is where she goes.
What they don’t understand is how to change the tire.
