普遍的な強調: 「All」を使った焦点化(All-Cleft)
only よりもドラマチックに one thing を際立たせることができますよ。
Grammar Rule in 30 Seconds
Use 'All' at the start of a sentence to show that something is the ONLY thing that matters.
- Start with 'All', then a subject and verb: 'All I need...'
- Follow with the verb 'be' (is/was): 'All I need is...'
- End with the focus: 'All I need is a coffee.'
- Never use 'what' after 'all' in this structure.
Overview
All-cleft(All分裂文)です。All-cleft は、文の要素を分解し、特定の情報を際立たせるために再構築する「分裂文(Cleft sentence)」の一種です。C1レベルの学習者にとって、この構文を使いこなすことは、単に文法的に正しい英文を作る以上の意味を持ちます。それは、聞き手の注意を自在に操り、文脈の中に「排他性」や「完結性」を吹き込む、いわば「言葉の演出家」になるためのスキルです。日本語では「〜なのは、〜だけだ」や「〜さえすればよい」といった助詞や特定の言い回しで表現されるニュアンスを、英語ではこの All を使った独特の構造で実現します。本稿では、この構文が持つネイティブスピーカー特有の直感から、日本人が陥りやすい文法的な罠まで、徹底的に掘り下げて解説していきます。All-cleft の仕組みを理解する鍵は、文頭の All の機能にあります。ここでの All は、単なる「すべて」という意味を超え、the only thing(唯一のこと)や the sum total of what...(〜することのすべて)という、限定的かつ包括的な代名詞として機能します。日本語の感覚で言うと、「私が欲しいのは〜だけだ」という時の「〜なのは」という「主題化」に近い働きをします。All-cleft は文全体の構造を作り変えます。I only want peace. | All I want is peace. |He just apologized. | All he did was apologize. |All-cleft では、All という「入れ物」を文頭に置き、その中に説明文(関係節)を流し込み、最後に be 動詞を使って「焦点」となる要素と結びつけます。この構造により、聞き手は All I want... と聞いた瞬間に、「あ、これから『唯一の望み』が提示されるんだな」と心の準備をすることができるのです。これは、英語が「結論(焦点)を後出しにして際立たせる」という戦略をとっていることを示しています。All に続く節の中で that や which といった関係代名詞が省略されるのが一般的であることです。これにより、All I need is... のようにリズムが良くなり、口語でも非常に好んで使われます。上級者としては、この「リズム感」こそが、単なる強調を超えた「説得力」を生むことを理解しておく必要があります。All-cleft を正しく組み立てるためのパターンは非常に厳格です。特に be 動詞の形や、焦点となる動詞の形には、上級者でも見落としがちなルールが存在します。All + (Subject + Verb) + is/was + [Focus]- 1
All(文頭): 文の主語として機能します。 - 2関係節 (S + V):
Allが何を指すのかを説明します。例:I need,she did,they are looking for。 - 3
be動詞: ここが最大の注意点です。Allは常に単数として扱われるため、後に続く焦点が複数形であっても、原則としてisまたはwasを使います。 - 4焦点 [Focus]: 強調したい名詞、動詞(不定詞)、あるいは
that節を置きます。
do / did / done を使い、be 動詞の後に動詞の原形(裸不定詞)を置くのが一般的です。- Pattern:
All+S+do/did+is/was+ (to) Verb - Example:
All he did was complain.(彼は文句を言っただけだった。)
to complain としても間違いではありませんが、現代英語の口語および標準的な書面語では to を省略した 裸不定詞 が圧倒的に好まれるという点です。これは、did という動詞の響きが、後の動詞と直接結びつこうとする心理的メカニズムが働くためだと言われています。All | 「唯一のこと」という枠組みを提示 |I can tell you | 範囲を限定する説明 |is | 主語と焦点をイコールで結ぶ(常に単数形) |the truth | 最も伝えたい核心的な情報 |only を使うよりも、All-cleft はよりドラマチックで、意図的な響きを持ちます。All we ask for is a fair chance.
- 日本語訳のポイント:「〜さえあれば」「〜だけでいい」というニュアンスが含まれます。
All I did was touch the button, and the whole system crashed!
- コンビニの店員に少し注意しただけなのに、大騒ぎになった……というような日常の「釈明」シーンでもよく使われます。
All I got for my birthday was a pair of socks.
- ここでは、
Allが「たったそれっぽっち」というネガティブなニュアンスを帯びています。
After hours of discussion, all they achieved was another delay.
All-cleft を使う際に陥りやすい、特有のミスを3つ紹介します。これらは日本語の干渉(L1 Transfer)や、英語の基本的な一致のルールに対する誤解から生じます。be 動詞を複数形にしてしまう (Number Agreement Error)are や were を使ってしまうミスです。- Incorrect:
All I need are your signatures. - Correct:
All I need is your signatures. - 解説: 英語の感覚では、
All I needは「私が必要とする『一連の事柄』」という一つのパッケージ(単数概念)として捉えられます。日本語でも「必要なのは、署名です」と言い、「署名らです」とは言わない感覚に似ていますが、英語では視覚的に複数名詞が直後に来るため、引きずられやすいのです。
only と All の重複 (Redundancy)only を混ぜてしまうミスです。- Incorrect:
All I want is only peace. - Correct:
All I want is peace. - 解説:
All自体にthe only thingという意味が含まれているため、onlyを付け加えるのは意味の重複(冗長)になります。ネイティブには非常に不自然に聞こえます。
be 動詞の時制をバラバラにしてしまうミスです。- Incorrect:
All he does was smile. - Correct:
All he did was smile.またはAll he does is smile. - 解説: 文全体が一つの出来事を描写しているため、時制は統一する必要があります。特に過去の出来事を釈明する際には、
didとwasのセットを意識しましょう。
All-cleft は他の強調構文とどう違うのでしょうか? 似た構造を持つ It-cleft や What-cleft と比較することで、その独自の立ち位置が明確になります。I want a coffee. | 単なる事実の伝達。 |All I want is a coffee. | 「それ以外はいらない」という排他性が最も強い。 |What I want is a coffee. | 「私が欲しいもの、それはね…」という、情報の提示に重点がある(中立的)。 |It is a coffee that I want. | 他の選択肢(紅茶など)との対比。「欲しいのは(紅茶じゃなくて)コーヒーだ」。 |What I want is...は、プレゼンテーションなどで「これから重要なことを言いますよ」と注目を集める際に使われる、やや「説明的」な響きです。All I want is...は、より「感情的」あるいは「切実」な響きを持ちます。例えば、喧嘩をしている最中にAll I want is an apology!と言うと、「謝罪さえしてくれればいいんだ(他には何も望まない)」というニュアンスが強く出ます。
Everything を使って Everything I want is you と言えますか?All は「〜だけ(限定)」に焦点がありますが、Everything は「〜のすべて(網羅)」に焦点があります。告白のシーンで All I want is you と言えば「君さえいればいい(他は不要)」となりますが、Everything I want is you は「私の欲しいものリストの全項目が君だ」という、少し理屈っぽい、あるいは過剰な響きになります。通常、この構文では All が好まれます。All I did was crying のように ~ing 形を使ってもいいですか?All I did was... の後は、動詞の原形(裸不定詞)か to 不定詞です。doing に対応するのは to do または do であるという文法的な照応関係があるためです。ただし、主語側の動詞が -ing 形(例:All she is doing is crying)であれば、整合性が取れます。All you need to do is sign the attached document.(添付書類に署名していただくだけで結構です)という表現は、相手の手間が少ないことを強調する、非常に洗練された丁寧な依頼方法です。that を省略しない方がいい場合はありますか?All that is required is... のように that を残すことがありますが、現代英語では、日常会話からビジネス文書まで、省略するのが一般的です。省略した方がリズムが生まれ、強調したい「焦点」に素早く到達できるため、上級者としては積極的に省略して「こなれた」英語を目指すべきでしょう。Structure of the All-Cleft

よくある質問 (8)
Yes, 'All that I want' is perfectly correct and slightly more formal than 'All I want'. Both are much better than 'All what'.
Because 'All' is treated as a single concept meaning 'the only thing'. In English, we often prioritize the singular nature of the 'only thing' over the plurality of the items.
It is neutral. You can use it in a job interview (`All I seek is a challenge`) or with friends (`All I want is a beer`).
Usually, no. The All-Cleft requires a form of the verb 'to be' (is, was, will be, has been) to link the 'All' clause to the focus.
They mean exactly the same thing. 'All I want' is just a shorter, more common way to say it.
Yes, absolutely. It's very common in romantic contexts.
Some non-standard dialects might use it, but in any professional, academic, or standard learning context, it is considered a mistake.
Usually, you negate the focus: 'All I want is NOT to go.' You can also negate the 'All' clause: 'All I don't need is more work,' but this is less common.
