Grammar Rule in 30 Seconds
Use 'Did' + Subject + Base Verb to ask about finished actions in the past.
- Start with 'Did' for all subjects (I, you, he, they). Example: 'Did you go?'
- Use the base form of the verb, NOT the past form. Example: 'Did he see?' (not 'saw')
- Answer with 'Yes, I did' or 'No, I didn't' for short responses.
Overview
Did you went to the party? と聞いて、不思議な顔をされたことはありませんか？あなただけではありません。これは、過去について話すときに人々が犯す一番のミスです。英語では、完了した動作について質問するときに did という言葉を使います。これは、あなたの文章にとって魔法のタイムマシンのようなものです。一度 did が登場すると、メインの動詞は通常の形でリラックスできます。 -ed のような厄介な過去形の語尾や不規則な変化を心配する必要はありません。このルールは、近況を報告し合うときの親友です。Netflixの番組やZoomでの面接、あるいは昨夜Uber Eatsで何を注文したかを尋ねるのに使います。シンプルでパンチが効いており、あらゆる会話に欠かせません。覚えておいてください： did が大変な仕事を代行してくれるので、あなたはする必要がありません。なぜ文法書は医者に行ったのでしょうか？緊張（Tense/時制）した瞬間が多すぎたからです！How This Grammar Works
did を強力なヘルパーと考えてください。文法用語では、助動詞と呼びます。その唯一の仕事は、聞き手に「ねえ、今は過去の話をしているんだよ！」と伝えることです。 did がすでに文の「過去感」を担っているため、メインの動詞は原形のままです。一人が重労働をすべてこなすチームのようなものです。 Did you go? と言えば、 did が過去形の部分です。go はただの普通の言葉です。一つの質問の中に過去形の言葉を二つ入れたいとは思いません。それは、二つの帽子を同時にかぶるようなものです。ただ馬鹿げて見えます。このルールは、英語のほとんどすべての動詞に適用されます。 play のような規則動詞でも、 see のような不規則動詞でも、 did はすべて同じように処理します。唯一の大きな反逆者は to be 動詞（ was と were ）ですが、それについては後ほど説明します。なぜ動詞は did が好きなのでしょうか？若いままでいられて、原形を保てるからです！
Formation Pattern
did という言葉で始めます。
you 、 she 、 they 、または your boss など）を追加します。
-ed なし、不規則変化なし）。
yesterday や to the gym など）を加えます。
Did I leave my keys? | 鍵を置き忘れたかな？
Did you see the news? | ニュースを見た？
Did she call you? | 彼女はあなたに電話した？
Did we win the game? | 試合に勝った？
Did they order pizza? | 彼らはピザを注文した？
Where や Why のような特定の質問をしたい場合は、その言葉を一番最初に置くだけです。例えば： Where did you go? や What did you eat? です。
When To Use It
Did you have fun? や Did you see that movie? と尋ねるかもしれません。仕事で何かを確認するのにも最適です。 Did you send that email? や Did you finish the report? などです。Did you just hear that noise? のようにごく最近のことや、 Did you live in London in 2010? のようにずっと前のことにも使えます。また、旅行のVlogやInstagramのキャプションにもぴったりの構造です。 Did we actually find the hidden beach? は素晴らしいフックになります！覚えておいてほしいのは、動作が完全に完了している必要があるということです。まだ続いている場合は、別のルールが必要です。
Common Mistakes
did と一緒にメインの動詞の過去形を使ってしまうことです。 Did you saw? や Did you went? とは絶対に言わないでください。 Did you see? と Did you go? でなければなりません。 did を、他の動詞から過去形の要素をすべて吸い取るスポンジと考えてください。もう一つの間違いは、 did を完全に忘れてしまうことです。語尾を上げて You went to the store? と言う人がいます。カジュアルなチャットなら通じるかもしれませんが、正式な質問としては文法的に正しくありません。また、 to be 動詞にも注意してください。 Did you be happy? とは言えません。代わりに Were you happy? を使ってください。 did と was/were は油と水のようなものです。同じ単純な質問の中で混ぜてはいけません！以前、霧を捕まえようとしました。霧（Mist）でした（Missed/逃した）。（わかりますか？Mist/霧？Missed/逃した？はい、次へ進みましょう）。Contrast With Similar Patterns
do/does ）と混同しがちです。 do/does は現在の習慣や事実のためのものであることを忘れないでください。 did は厳格に過去のためのものです。- 現在：
Do you like sushi?（一般的に） - 過去：
Did you like the sushi?（昨夜食べた特定の寿司）
- 肯定文：
You went home.（過去形を使用） - 質問：
Did you go home?（didがあるため原形を使用）
did が助けに入り、動詞は休みを取ります。誰が仕事をしているかがすべてです！Quick FAQ
he や she にも did を使いますか？
はい！現在形（ do/does ）とは異なり、 did は誰に対しても同じです。 Did I 、 Did she 、 Did they ― 決して変わりません。
Yes や No だけで答えてもいいですか？
いいですが、 Yes, I did や No, I didn't と言う方が自然です。その方がずっとネイティブスピーカーらしく聞こえます！
was と were はどう使い分けますか？
それらは描写や場所のためのものです。動作には Did を使います。 Were you tired? （描写）対 Did you sleep? （動作）。
テキストメッセージで did を使っても大丈夫ですか？
もちろんです！フォーマルなメールからWhatsAppのグループチャットまで、あらゆる文脈で質問する標準的な方法です。
なぜ英語はこうなっているのですか？
英語は助動詞が大好きだからです！ did をマスターすれば、 will 、 can 、 should もすべて同じように機能することがわかるでしょう。

Smart Tips
Remember: 'Did' is the past tense marker. It's like a sponge that soaks up all the past tense from the other verbs.
Check if the verb is 'to be'. If it is, throw 'did' away and use 'Was' or 'Were'.
Use the 'Did-ja' contraction for 'Did you' in informal settings.
Use the negative question 'Didn't you...?' to show your emotion.
発音

文化メモ
In the UK, people often use the Present Perfect ('Have you finished?') where Americans might use the Past Simple ('Did you finish?').
Americans use 'Did you...' very frequently for recent past actions, even if the result is still relevant.
You might hear 'Did y'all...' when addressing a group of people.
The use of 'do' as an auxiliary (do-support) emerged in Middle English and became standard in Early Modern English (the time of Shakespeare).

No. You must say `Did you go?`. The word `did` already tells us it is the past, so the main verb stays in the base form.
No. For the verb 'to be', you just swap the subject and the verb: `Were you happy?` (not `Did you were happy?`).
Yes! Unlike the present tense (do/does), `did` is the same for every subject in the past tense.
Use a short answer: `Yes, I did` or `No, I didn't`. This sounds more natural than just saying `Yes` or `No`.
Use `Did you see` for a specific time (yesterday). Use `Have you seen` for general experience (ever).
Yes. You can say `Didn't you see the sign?` to express surprise.
When the question word (Who/What) is the subject of the sentence, we don't use `did`. We just use the past tense verb.
No. Modal verbs like `can` (could) and `must` (had to) have their own ways of forming questions and do not use `did` support.

¿Comiste?
English requires an auxiliary ('did'); Spanish does not.
As-tu mangé? / Est-ce que tu as mangé?
French uses the auxiliary 'have' (avoir) more often than English uses 'did'.
Hast du gegessen? / Aßt du?
German uses verb inversion; English uses 'do-support'.
Tabemashita ka? (食べましたか)
Japanese is agglutinative (adds endings); English uses word order and auxiliaries.
Hal akalta? (هل أكلت؟)
In Arabic, the verb still changes to the past form; in English, it stays base.
Nǐ chī le ma? (你吃了吗？)
Chinese uses particles at the end; English uses an auxiliary at the start.
