平叙文のまま上げる疑問(You're leaving?)Asking Without Flipping Anything
疑問文 / Questions
語順をまったく変えず、語尾を上げるだけでも疑問になります。You're leaving? / He said that?。ただしこれは中立の質問ではありません。「すでにそうだと思っている」ことを前提にした確認や、驚きの表明です。何も知らない状態から尋ねるなら、ひっくり返した Are you leaving? を使います。
You can ask a question without touching the word order at all — just lift your voice at the end. "You're leaving?" "He said that?" But this isn't a neutral question. It confirms something you already believe, or registers surprise. To ask from a standing start, flip it: "Are you leaving?"
Inversion is a signal that you're about to ask for information. Skip the signal and lift only your voice, and the sentence implies you already hold half the answer. That's why these turn up after someone has spoken, or when the situation in front of you suggests the answer. Without the rise it's just a statement, so this belongs mainly to speech.
すでに察している場面When you already suspect it
You'reこの文の組み立て【現在進行】いま進行中のことを言う形。日本語の「〜している」と重なるが、英語では「一時的である」ことを示す働きも持つ。leaving? It's only eight.
帰るの? まだ8時だよ。
相手が席を立った様子を見ての確認。驚きが乗る。Prompted by seeing the person stand up, and it carries surprise.
"I quit my job." "You quit?"
「仕事やめたんだ」「やめたの?」
相手の発言をそのまま返す聞き返し。An echo, handing the speaker's own words back.
"I saw Tom yesterday." "You saw who?"
「きのうトムに会った」「誰に会ったって?」
聞き取れなかった箇所に疑問詞を置く。前には出さない。The wh- word stays where the missing piece was; it doesn't move to the front.
倒置する(中立の質問)
前提を置かずに情報を求める。初めて尋ねるときはこちら。Asks for information without assuming anything. The choice for a first ask.
Are you coming to the party?
パーティー来る?
倒置しない(確認・驚き)
そうだろうと見込んだうえでの確認。驚きや疑いが乗ることもある。Checks something you expect to be true, sometimes with surprise or doubt attached.
A statement-shaped question assumes you already believe the answer. Use one before you've heard anything and it lands as a presumption. Pairing it with a negative makes that worse, since it signals you expect the person to stay away. When you want a neutral ask, flip the order. Save the statement shape for confirming something you've just been told or just observed.
You did what?何したって?聞き返しの定型。疑問詞をその場に残して驚きを出す。The standard echo, keeping the wh- word in place to carry the shock.
He said that?彼がそう言ったの?相手の発言を受けた確認。倒置しないので驚きが残る。Confirms what you've just been told, and the missing flip leaves the surprise in.
Sorry, you're going where?ごめん、どこに行くって?聞き取れなかった部分にだけ疑問詞を置く。Sorry を添えると丁寧。Marks only the part you missed. Adding Sorry keeps it polite.
Wait, really?え、ほんとに?驚きの聞き返しをさらに短くした形。会話で頻出。The shortest form of the surprised echo. Extremely common in speech.
