What Is a Cleft Sentence? A Simple Explanation With Examples

"It was Sarah who won the competition" and "Sarah won the competition" say the same thing — but they don't emphasize the same thing. The second sentence is neutral; the first one puts a spotlight on Sarah, as if answering "who won?" directly. That spotlighting structure is called a cleft sentence, and it's one of the most useful tools in English for controlling what a listener or reader focuses on, once you know how to build one.

What is a cleft sentence?

A cleft sentence takes a normal sentence and splits ("clefts") it into two parts to push one specific piece of information into focus. Instead of "Sarah won the competition," you get "It was Sarah who won the competition" — same facts, but now "Sarah" (not the winning, not the competition) is the part the sentence is built around.

This matters most in writing and formal speech, where you can't rely on vocal stress to signal emphasis the way you can in casual conversation. Say "SARAH won the competition" out loud and the stress does the work; on the page, a cleft sentence does the same job with word order instead of your voice.

The two types of cleft sentences

English has two main cleft patterns, and they emphasize slightly different things.

It-cleft: "It + is/was + [the focus] + that/who + [the rest]."

• It was Sarah who won the competition. (focus: Sarah, not someone else)
• It wasn't his technique but his dedication that made him successful. (focus: dedication, not technique)
• It was in 1969 that the first moon landing happened. (focus: the date)

The it-cleft is the more common pattern and works for people, things, times, and reasons — whatever you put right after "it was" becomes the focus.

Wh-cleft (also called a pseudo-cleft): "What + [clause] + is/was + [the focus]."

• What I need is a good rest. (focus: a good rest, not something else)
• What surprised me most was her reaction. (focus: her reaction)

The wh-cleft tends to sound more natural in speech than the it-cleft, and it's especially useful for emphasizing what someone wants, needs, or feels, rather than who did something.

Why use a cleft sentence instead of a normal one?

A plain sentence treats every part more or less equally. A cleft sentence tells the reader "pay attention to this part specifically" — useful whenever you're correcting a misunderstanding, contrasting two things, or just want one fact to land harder.

• Correcting: "It wasn't the traffic that made me late — it was the meeting running over." The cleft makes the contrast explicit instead of burying it in a longer explanation.
• Answering a specific question: If someone asks "who broke the vase?", "It was the cat" is a tighter, more natural answer than "The cat broke the vase" — the cleft matches the shape of the question.
• Formal or persuasive writing: journalism and academic writing use clefts constantly for rhetorical weight — "What the data shows is a clear decline" reads more deliberate than "The data shows a clear decline."

How to build your own cleft sentences

Start from a plain sentence and decide what you actually want to emphasize — that choice determines which word goes into the cleft frame.

1. Take a normal sentence: The manager approved the budget.
2. Pick the part to emphasize — say, the manager, not the budget.
3. Drop it into the it-cleft frame: It was the manager who approved the budget.
4. Or, if you want to emphasize an action or need instead of a person, use the wh-cleft frame: What the manager did was approve the budget.

A quick sanity check: if your sentence sounds like it's specifically ruling out an alternative ("it was X, not Y"), you're using a cleft correctly. If nothing is being singled out, a plain sentence is usually the more natural choice — clefts used everywhere read as over-emphatic rather than precise.

Cleft sentences show up early on English writing and speaking assessments, and they're worth building active recall for rather than just recognizing when you see one — see our deeper Cleft Sentences reference for the full formula, more examples, and how clefts compare to related emphasis structures like inversion. If sentence-level grammar patterns like this are hard to hold onto, spaced repetition is the same mechanism that works for vocabulary — build a grammar-focused set with example sentences on one side and the pattern name on the other, and let the review timing do the remembering for you.
