Grammar Rule in 30 Seconds
Use 'haven't' or 'hasn't' followed by a past participle to talk about things that didn't happen in an unfinished time period.
- Use 'haven't' for I, you, we, they (e.g., I haven't eaten).
- Use 'hasn't' for he, she, it (e.g., She hasn't arrived).
- Always use the Past Participle (V3), never the base form or past simple.
Overview
Present Perfect Negativeが活躍する場面だ。これは、まだ人生で起こっていないことについて話したいときに必要な文法ツールなんだ。あるいは、今日まだ終えていないこととかね。過去と現在の「未達成」な自分をつなぐ架け橋のようなもの。「まだ〜ない」とか「一度も〜ない」の時制だと考えてみて。これは単なる否定文じゃなくて、それ以上の意味を持っている。期待の重みが込められているんだよ。「I haven't eaten」（まだ食べていない）と言えば、今おなかが空いているんだろうなって伝わる。「I didn't eat」（食べなかった）と言えば、それは単なる歴史の本だ。一方は生きていて、もう一方は閉じられた章なんだ。Zoomでの就職の面接ではひっきりなしに使うだろうし、ドラマについて友達とメッセージをやりとりするときにも使う。まだ届いていない注文についてフードデリバリーアプリに文句を言うときでさえね。まさに究極の「まだ〜ない」時制なんだ。これは、過去に始まって、今この瞬間まで続いている期間を表す。もしコーヒーを飲み終えていなければ、カップはまだ君の手の中にある。もしパリに行ったことがなければ、パスポートはそのスタンプをまだ待っている。これは可能性の時制であり、FOMO（取り残されることへの恐怖）の時制でもある。だって、何かをしたことがないなら、まだするチャンスがあるってことだからね！ただ、このルールを学ぶのを次の世紀まで待たないように。How This Grammar Works
Present Perfect Negativeは、今現在の結果や物事の状態に焦点を当てるんだ。何かが起こらなかったのが*いつ*だったかは気にしない。今この時点までそれが起こっていないということだけが重要なんだ。人生が巨大なチェックリストだと想像してみて。この時制は、まだ空っぽのチェックボックスに印をつけるようなものだね。「未完了の時間」という概念と一緒に使われる。これは「今日」「今週」、あるいは「人生全体」かもしれない。その期間が終わっていなければ、この時制を使うんだ。Past Simpleとは違う。なぜならPast Simpleは行き止まりだからだ。Present Perfectは開かれたドアなんだ。「今日、お母さんに電話してないんだ」と言えば、今日はまだ続いている。いい子でいる時間はまだある！でも、「昨日、お母さんに電話しなかった」と言えば、まあ、昨日はもう過ぎ去ってしまった。チャンスを逃したんだね。これは最近の出来事にも使う。だから、ちょうど起こっていないようなことにも使うんだ。まだ受信トレイに届いていないメールのようにね。これは、過去の非行動が現在に及ぼす結果についてなんだ。もしhaven't slept（寝ていない）なら、今疲れている。この文法は、「しなかったこと」と「今の状態」を結びつけるんだ。
Formation Pattern
Legoのセットを組み立てるようなもの。正しい順番で3つの特定のピースが必要なだけ。文を作るには、次のステップに従ってね：
Subject（主語：I, you, we, they, he, she, it）で始める。
have か has を加える。he/she/it には has を、その他すべてには have を使う。
not を加える。
Past Participle（過去分詞）で締めくくる。
Past Participle は過去形とまったく同じ見た目（-edで終わる）。不規則動詞の場合は、まあ、ちょっと厄介な形を覚える必要があるね！
have not は haven't に
has not は hasn't になります。

When To Use It
- Life Experiences: 人生で一度もやったことがないことについて話すとき。「I
haven'tever been to a rave.」（レイブには一度も行ったことがないんだ。） - Unfinished Time: 時間の期間がまだ続いているとき。「I
haven'tchecked my email *this morning*.」（*今朝は*まだメールをチェックしていない。） - Recent Events (with 'yet'): 何かがすぐに起こると期待しているとき。「The
Uberhasn'tarrived yet.」（Uberがまだ着かない。） - Changes Over Time: 何も変わっていないと言うため。「The weather
hasn'timproved at all.」（天気は全く良くなっていない。） - Current Result: 行動しなかったことが現在の結果につながっているとき。「I
haven'tdone my laundry, so I have no clean shirts.」（洗濯をしていないから、きれいなシャツがない。）
Instagramのキャプションで：「I haven't been this happy in years!」（ここ数年でこんなに幸せだったことはない！）。職場のSlackメッセージで：「The client hasn't sent the feedback.」（クライアントがまだフィードバックを送ってきていない）。これは現代社会の言葉なんだ。DoorDashの配達員やFortniteのアップデートが終わるのを待っているときに言う言葉だね。それに、とても丁寧な言い方でもある。「You didn't send the file」（あなたがファイルを送らなかった）と言うより、「I haven't received the file」（ファイルを受け取っていません）と言う方がずっと柔らかく聞こえる。人の失敗ではなく、欠けている結果に焦点を当てるんだ。1時間も鳴きやまない猫に話しかけている場合は別だけどね。その時は、どんどん焦点をずらしちゃえ！
Common Mistakes
- The
DidTrap: 多くの人がPresent Perfectでdidを使おうとする。✗ "I haven't did it.と言ってしまう。正しくは ✓
Ihaven'tdone it." だ。覚えておいて、haveの後には常にPast Participle（動詞の3番目の形）が来るのであって、単純な過去形は絶対に来ない。 - The
Has/HaveMix-up: he/she/it にhaven'tを使ってしまう。✗ "He haven't seen it.は間違いで、✓
Hehasn'tseen it." でなければならない。 - Missing Participles: 動詞を変えるのを忘れてしまう。✗ "I haven't see the movie.
最後に
I-nが必要だ。✓haven'tseen the movie." - Wrong Time markers: 完了した時間表現を使ってしまう。✗ "I haven't seen him yesterday.
特定の過去の時間には
I didn't see him yesterdayPast Simpleを使う。✓と言うか、✓
Ihaven'tseen him since yesterday." と言おう。 - The 'Yet' Overload: すべての文に 'yet' をつけてしまうこと。「I
haven'teaten.」で全く問題ない。期待を強調したい場合を除いて、必ずしも 'yet' は必要ないんだ。
Contrast With Similar Patterns
Past Simple Negative（didn't + 動詞の原形）だ。どうやって選べばいい？didn'tを使う。「I didn't go to the gym *on Monday*.」（*月曜日に*ジムに行かなかった）。これは過去についての事実だ。haven'tを使う。「I haven't gone to the gym *this week*.」（*今週は*ジムに行っていない）。週はまだ終わっていない！君の筋肉にはまだ希望がある。never だ。「その映画を見たことがない」は "I haven't seen that movie« とも »I have never seen that movie" とも言える。never の方がずっと強い。人生で一度も、ゼロ回だという意味。haven't はもっと中立的。never を使うなら、not は使わないで。✗ "I haven't never seen it" は二重否定だ（ラップの曲ならクールかもしれないけど、英語の試験ではダメだよ）。Quick FAQ
ずっと昔に起こったことにも haven't は使えますか？
時間の期間がまだ開いている場合だけね。「I haven't seen my childhood friend in 20 years.」（幼なじみとは20年間会っていない）。20年という期間が今も続いているんだ！
hasn't より has not の方が良いですか？
WhatsApp や Instagram のコメントで？いや、hasn't の方がずっと自然だよ。大学のフォーマルなエッセイでは？ has not の方が無難だね。
Past Participle の形がわからない場合はどうすればいいですか？
迷ったら検索して！またはパターンを探してみよう。ほとんどの動詞は規則動詞だから。でも 'go' や 'see' で推測しないでね。'gone' と 'seen' であって、'goed' や 'seed' ではない。Google Translate は文脈によってはこれを間違えることがあるから、ちゃんとした辞書で確認しよう！
否定文ではいつも yet が必要ですか？
いいえ。yet は「これがすぐに起こることを期待している」というニュアンスを付け加えるだけ。「I haven't finished」は単なる陳述。「I haven't finished *yet*」は「今取り組んでいる最中です」という約束になる。上司とのトラブルを避けるのに最適だね！
haven't と ever を一緒に使っても大丈夫ですか？
実は、haven't と ever は普通、疑問文で一緒に使うんだ。否定文では haven't か have never を使う。「I haven't ever been there」も可能だけど、「I've never been there」の方がずっと一般的。シンプルに考えよう！脳が感謝するよ。
*たった今*起こらなかったことについて話すにはどうすればいいですか？
just は肯定的なことによく使うけど、否定的なことには haven't + yet か still haven't を使うのが普通だよ。「I *still* haven't received the code.」（*まだ*コードを受け取っていない）。この still は、ちょっとしたイライラ感を加える。なかなか表示されない二段階認証コードを待っている時みたいにね。
否定文での gone と been の違いって何ですか？
いい質問だね！否定文では、しばしば同じ意味になることがある。「I haven't been to London」は、一度も訪れたことがないという意味。「He hasn't gone to work」は、彼が今、家にいるという意味だ。一つは経験についてで、もう一つは今現在の場所についてなんだ。

Smart Tips
Use 'I haven't yet' instead of 'I didn't'. It sounds like you are still working on it.
Check if the verb is in the Present Perfect. These words are almost always a signal for this tense.
Remove the 'n't' from 'haven't'. 'Never' already makes the sentence negative.
Always use 'haven't' if you are still alive! Your life is an unfinished time period.
発音
Contraction Stress
In the negative, the contraction 'haven't' or 'hasn't' usually receives more stress than the positive 'have' or 'has'.
The 't' sound
In fast speech, the final 't' in 'haven't' is often unreleased or 'glottalized' before a consonant.
Falling Intonation

Story
Meet Bob. Bob is a procrastinator. Today, Bob has a long list. It is 5:00 PM. Bob says, 'I haven't washed the car, I hasn't cooked dinner, and I haven't called my mom.' Because the day isn't over, Bob uses the Present Perfect Negative.

文化メモ
British speakers use the present perfect negative much more frequently than American speakers for recent actions.
Americans often substitute the Past Simple Negative ('I didn't eat yet') where British speakers would strictly use the Present Perfect.
In AAVE, 'ain't' is a common substitute for 'haven't' or 'hasn't'.
The 'have' + past participle construction emerged in Old English, originally meaning 'I possess [something] in a completed state'.

よくある質問 (8)
No. You cannot use specific past time markers like `yesterday` with the present perfect. Use the past simple: `I didn't see him yesterday`.
Use `hasn't` only for the third person singular (`he`, `she`, `it`). Use `haven't` for everything else (`I`, `you`, `we`, `they`).
No. `I haven't got` usually means 'I don't possess' (Present Simple meaning), while `I haven't had` is the negative of 'I have had' (Present Perfect).
In American English, the Past Simple is often used for recent actions where British English would use the Present Perfect. Both are understood, but the Present Perfect is more 'standard' globally.
No, that's a double negative. Say `I have never been` or `I haven't ever been`.
Yes, you must use the Past Participle (V3). For example, `haven't gone`, not `haven't go` or `haven't went`.
Use `have not` in formal writing, like business reports, academic essays, or legal documents.
Not necessarily. It usually implies that the action hasn't happened *up to now*, but it might happen in the future.
