Overview

As you advance in your English journey to C1 level, simply conveying information isn't enough; you need to express ideas fluently and spontaneously with impact and nuance. This chapter on English using cleft sentences to highlight information is your secret weapon for achieving just that. Far from being a mere grammatical curiosity, mastering cleft sentences – including It-clefts and Wh-clefts – empowers you to take control of your message, focusing your listener's attention precisely where you want it.
Imagine being able to subtly (or not so subtly!) correct a misunderstanding, add dramatic flair to a story, or emphatically state a truth. These advanced structures, like the Emphatic Do/Does/Did, the All-cleft, and those that spotlight 'when' or 'where' something happened, give your English a persuasive edge and C1-level sophistication. They're about more than just correctness; they're about communication strategy, making your points resonate deeply and transforming your speaking and writing from merely clear to truly compelling.

How This Grammar Works

At its heart, this grammar is about shifting the emphasis within a sentence. Instead of a straightforward statement, we restructure it to bring a specific piece of information into the spotlight. Think of it as putting a verbal spotlight on the most crucial part of your message.
We begin with the foundational concept of emphasis: the Emphatic Do/Does/Did. When you say,
I *do* like it!
you're not just confirming; you're often contradicting an assumption or adding sincere warmth, almost like verbal bolding. This simple addition elevates the verb.
Building on this, It-clefts are structures like
It was X that Y
or
It is X who Y.
They allow you to take any part of a sentence – the subject, object, time, or place – and place it directly after 'It is' or 'It was' for maximum impact. For example, instead of
My boss suggested the idea,
you can say,
It was my boss who suggested the idea,
clearly highlighting the person responsible. Similarly,
It was yesterday that the decision was made
puts the focus squarely on the timing.
This is incredibly useful for clarification, contrast, or adding dramatic weight.
Then we have Wh-clefts, often starting with 'What', 'Who', 'Where', 'When', or 'Why'. These are fantastic for spotlighting actions or needs, making your statements more persuasive and dynamic. For instance, instead of
I need a long break,
you can express it more forcefully as,
What I need is a long break.
The All-cleft is a specific type of Wh-cleft that uses 'All' to indicate exclusivity, such as
All I want is a quiet evening,
emphasizing that nothing else matters.
By strategically employing these structures, you're not just speaking English; you're truly shaping your message with C1 precision.

Common Mistakes

  1. 1Overuse in simple contexts: *It is that I went to the store yesterday.*
Correction: *I went to the store yesterday.* (Clefts are for emphasis, not everyday simple statements.)
Explanation: While powerful, cleft sentences add formality and emphasis. Using them unnecessarily can make your speech sound unnatural or overly dramatic. Reserve them for moments when you genuinely want to highlight information.
  1. 1Incorrect verb agreement or pronoun usage in It-clefts: *It was them who arrived late.*
Correction: *It was they who arrived late.* (More formally correct, though 'them' is common informally). Or, *It was I who made the mistake.* (Not *It was me who...*)
Explanation: The pronoun after 'It is'/'It was' should ideally be in the subject form (I, he, she, we, they) in formal contexts, especially when followed by 'who' or 'that'. The verb in the relative clause should also agree with the highlighted subject, e.g., *It is the students who *are* protesting.*
  1. 1Confusing structure of Wh-clefts with direct questions: *What did he do was steal the money.*
Correction: *What he did was steal the money.*
Explanation: Wh-clefts are statements that use a 'wh'-word to introduce the emphasized clause, followed by a form of 'be'. They are not interrogative sentences, so avoid question word order in the first part of the cleft.

I thought Sarah was going to present her findings today.

B

Oh, she *did* present them! You must have stepped out. It was David who forgot to update the schedule.
A

A

This report is a mess. I can't understand the main point.
B

B

I agree. What this report needs is a clear executive summary at the beginning. Otherwise, it's just a wall of text.

So, you're saying the project failed because of budget cuts?
B

B

Not entirely. It was the lack of communication that truly undermined the project, more than anything else.

Quick FAQ

Q

When should I use a cleft sentence instead of a simple sentence?

You should use a cleft sentence when you want to put particular emphasis on one part of your message, to clarify, correct, contrast, or add drama. For example, to correct a misunderstanding or to highlight a specific detail that's crucial to your point.

Q

Are cleft sentences always formal?

While they can lend a more formal tone, especially in writing, many cleft structures, like

What I mean is...
or "It's you I'm talking to," are very common in spoken, informal English to add emphasis or clarity. The choice depends on the specific structure and context.

Q

What's the main difference between It-clefts and Wh-clefts?

It-clefts (e.g.,

It was John who left
) emphasize a specific noun or pronoun (person, object, time, place). Wh-clefts (e.g.,
What John did was leave
) typically emphasize an action or a generalized idea, often focusing on the 'what' of a situation.

Q

Can I use clefts in writing as well as speaking?

Absolutely! Cleft sentences are excellent tools for both written and spoken English. In writing, they can make your arguments more persuasive and highlight key information for the reader. In speaking, they add natural emphasis and allow you to guide your listener's attention dynamically.

Cultural Context

Native English speakers instinctively use these patterns not just for grammatical correctness, but for their communicative impact. They're masters of strategic emphasis. In everyday conversation, you'll hear emphatic do and Wh-clefts (especially
What I need is...
) frequently to express strong opinions or needs.
It-clefts are common for correcting misinformation or adding weight to a statement, often with a slight pause for dramatic effect. While formal writing might prefer
It was I who...
, casual speech often opts for
It was me who...
, showcasing the flexibility and natural evolution of these structures. They are key to sounding truly fluent and spontaneous.

強調が命!

doを声に出して強調しないと、ただ文法がごちゃごちゃしてるだけみたいに聞こえちゃいます。この助動詞を「パンチ」するつもりで発音してみて!
I did tell you!
frontend.learn_grammar.from_rule: 強調:本当に好きなんです! (Emphatic Do/Does/Did)
💡

「これだけ」という感覚

他の可能性をすべて排除して、核心だけを伝えたい時にこの形がベストです。"All I'm saying is that it's complicated."

「What」をどんどん使ってみましょう

It-Cleftの文を完成させるため、正しい関係代名詞を選びましょう。

It was my new phone ___ I lost at the concert.

✓ Correct! ✗ Not quite. Correct answer: that
'my new phone' は物なので、'that' が適切な関係代名詞です。'who' は人、'whose' は所有を表します。

次のAll-cleftの文の間違いを見つけて直してください。

Find and fix the mistake:

All he needed are more time to finish the report.

✓ Correct! ✗ Not quite. Correct answer: All he needed was more time to finish the report.
'more time' が複数のように感じられても、この構造では 'all' を受ける動詞は単数形になります。過去の話なので 'was' が適切です。

frontend.learn_grammar.from_rule: 普遍的な強調: 「All」を使った焦点化(All-Cleft)

Wh-cleft文の間違いを見つけて修正しなさい。

Find and fix the mistake:

What he did was to ran away from the spider.

Find and fix the mistake:

It were the unexpected results that surprised everyone.

よくある質問 (6)

いいえ、否定文ではすでにdoが必要なので使いません。否定を強調したい場合は、通常notを強調するか、reallyを使います。例えば、「I really do NOT want to go.」(本当に、行きたくない!)のように言いますよ。
はい、大丈夫です!タスクが完了したことを明確に伝えたり、謝罪の気持ちを誠実に示したりするのにとても役立ちます。例えば、「We **did** review your application last week.」(先週、確かにあなたの応募書類を確認いたしました。)のように使えます。
特定の行動や物だけに「スポットライト」を当てるためです。the one thing を強調して、それ以外は重要ではないというニュアンスを出せます。
'just' も強調になりますが、'All I did was...' の方が「それしかやっていない」という全否定のニュアンスが強く、よりドラマチックです。
Wh-cleftsの主な機能は、文の特定の部分に鋭い焦点を当て、それを最も重要な情報として際立たせることです。考えやモノ、行動、理由などを強調するのに役立ちます。例えば、「何よりも私が欲しいのは、平和です」という気持ちを表すために
What I want most is peace.
と言えます。
Wh-cleftsは、通常は後に来る情報を前面に出すために文を再構築します。例えば、「I want coffee」というシンプルな文は、「What I want is coffee」となり、「coffee」に強調が置かれます。これにより、「他のものじゃなくて、コーヒーなんだよ」というニュアンスが加わります。
