Grammar Rule in 30 Seconds
Use 'nor' to link two negative ideas by flipping the subject and auxiliary verb in the second clause.
- Start with a negative statement like 'I don't smoke.'
- Add 'nor' followed by an auxiliary verb: 'nor do I.'
- The second part must look like a question: 'nor does he' (not 'nor he does').
Overview
nor inversion（norを用いた倒置）は、まさにその一歩先へ進むための重要な文法要素です。nor inversion とは、先行する否定的な内容に対して、さらに別の否定的な情報を付け加える際に使われる形式的な構造です。日本語では「〜もまた、〜ない」という表現に相当しますが、英語では nor という接続詞が文頭に来ることで、その後の語順が「疑問文と同じ形」にひっくり返る（倒置が起きる）という特徴があります。and...not either（〜もまたない）という表現に比べ、nor inversion は非常に洗練された、説得力のある響きを持つからです。ビジネス文書、学術論文、あるいは格調高いスピーチなどでこの構造を使いこなせれば、あなたの英語は一気に「教養あるネイティブスピーカー」のレベルへと引き上げられます。日本語には「語順を疑問文の形にすることで否定を強調する」というルールが存在しないため、日本人学習者にとっては非常に意識的な練習が必要な箇所です。本稿でその仕組みを完璧にマスターしましょう。nor は 「否定の極性を持つ等位接続詞（coordinating conjunction with negative polarity）」 です。これは、前の文で述べられた「否定的なトーン」を引き継ぎ、次の節へと繋げる役割を果たします。- 日本語の場合： 「彼は肉を食べないし、魚も食べない。」のように、文末の動詞を否定形（〜ない）にすることで否定を表します。語順は基本的に変わりません。
- 英語（nor inversion）の場合：
He doesn't eat meat, nor does he eat fish.のように、norが現れた瞬間に、後ろの主語と助動詞が入れ替わります。
does he という語順になるのは、聞き手に対して「これからもう一つの否定的な事実を述べますよ」という強力なシグナルを送っているのです。nor は単なる and ではありません。and は情報を「追加」するだけですが、nor は前の否定文と後ろの否定文を論理的に等価なものとして強固に結びつける働きがあります。これにより、文全体にリズムとバランスが生まれ、修辞的（レトリック的）な美しさが加わるのです。nor inversion を正しく作るための黄金律は、「nor + 疑問文の語順」 です。具体的には、以下の構成になります。[最初の否定文] , nor + [助動詞/be動詞/完了形のhave] + [主語] + [動詞の原形など] ...nor 節の構造 | 例文 |She doesn't like... | nor + does/do + S + 原形 | She doesn't like coffee, nor does she like tea. |They didn't call... | nor + did + S + 原形 | They didn't call, nor did they send an email. |He isn't rich... | nor + is/are/am/was/were + S | He isn't rich, nor is he famous. |We cannot accept... | nor + can/will + S + 原形 | We cannot accept this, nor can we ignore it. |I haven't seen... | nor + have/has + S + 過去分詞 | I haven't seen him, nor have I heard from him. |nor 自体に否定（not）の意味が含まれているため、倒置した後の節の中で not を繰り返してはいけません。これは日本語の「〜もない」という感覚に引っ張られると間違えやすいポイントです（詳細は Common Mistakes セクションで解説します）。nor inversion は、いつでも使えば良いというわけではありません。その「重み」を理解し、適切な場面で使うことが B2 レベルの賢明な選択です。and...not either よりも nor を使った方がプロフェッショナルな印象を与えます。The results were not conclusive, nor were they consistent with previous studies.
We will not falter, nor will we fail.
The night was not cold, nor was there any wind.
nor を使うことでその強調が際立ちます。I do not know the answer, nor do I care to find out.
nor inversion を使うと、少し「堅苦しすぎる」あるいは「芝居がかっている」と思われる可能性があります。日常会話では、後述する and neither... や ...not either を使うのが自然です。しかし、会議の席や公式なプレゼンであれば、積極的に nor を使ってみてください。nor の後を普通の語順にしてしまいがちです。- ❌ Incorrect:
The hotel wasn't clean, nor it was comfortable. - ✅ Correct:
The hotel wasn't clean, nor was it comfortable. - 解説:
norは「倒置のスイッチ」です。norを言った瞬間に、脳を「疑問文モード」に切り替える訓練をしましょう。
nor の後に再び not を入れてしまうミスです。- ❌ Incorrect:
He didn't apologize, nor did he not explain. - ✅ Correct:
He didn't apologize, nor did he explain. - 解説:
norはand + notの合体形だと考えてください。すでに否定が含まれているので、後ろにnotを置くと「説明しなかったわけではない（＝説明した）」という逆の意味になってしまいます。
do で受けてしまうミスです。- ❌ Incorrect:
I cannot swim, nor do I dive. - ✅ Correct:
I cannot swim, nor can I dive. - 解説: 前の文が
cannot（助動詞）なら、後ろもcanを使うのが原則です。これは英語の「並行構造（Parallelism）」という美学に基づいています。
...nor + 倒置 | 高 (Formal) | nor + 疑問文の語順 | 非常に格調高く、強調が強い。 |Neither...nor... | 中〜高 | Neither A nor B | AとBの両方を否定。名詞や句を繋ぐことが多い。 |and neither + 倒置 | 中 (Neutral) | and neither + 疑問文の語順 | nor よりは少し柔らかいが、まだ丁寧。 |...not...either | 低 (Informal) | 文末に either を置く | 最も一般的で、日常会話向け。 |- 1
I don't like it, and she doesn't either.(カジュアル：彼女も好きじゃないんだ。) - 2
I don't like it, and neither does she.(標準的：そして彼女もまた好きではない。) - 3
I do not like it, nor does she.(フォーマル：私はそれを好まず、彼女もまた同様である。)
Neither...nor... との違い：Neither...nor... は「相関接続詞」と呼ばれ、最初から「AもBも〜ない」とセットで提示する場合に使います。一方、今回の nor inversion は、まず一つの否定文を完結させた後、そこに「さらに言えば...」と付け加えるニュアンスが強いです。nor で文を始めることはできますか？"I don't believe him.« »Nor do I."（「彼を信じない」「私もだ」）nor は使えますか？nor はあくまで否定の継続です。肯定文の後に「〜もまた」と続けたい場合は、and so + 倒置（例：I like it, and so does she.）を使います。do/does、過去形なら did を補ってください。例：He never smokes, nor does he drink.nor の前にコンマを置くのが正しい句読法です。ただし、節が非常に短い場合は省略されることもあります。Inversion Patterns by Auxiliary Verb

Meanings
A grammatical structure used to connect two negative clauses where the second clause undergoes subject-auxiliary inversion to emphasize the addition of the second negative point.
Standard Negative Addition
Adding a second negative action or state to a previous negative statement.
“She doesn't eat meat, nor does she eat dairy.”
“They haven't arrived, nor have they sent a message.”
Emphatic/Literary Denial
Used in formal speeches or literature to strongly negate multiple possibilities.
“Never had he seen such beauty, nor would he ever again.”
“The king would not surrender, nor would his people lose hope.”
Correlative Pairing
Used as the second half of the 'neither... nor' construction, though the inversion is most striking when 'nor' starts a new clause.
“Neither did he apologize, nor did he show any remorse.”
“Neither will the price go down, nor will the quality improve.”

Smart Tips
Use 'nor' instead of 'and also... not'. It makes your writing look more professional.
Remember that 'be' verbs (am, is, are, was, were) invert directly without needing 'do'.
Stop! 'Nor' already has the 'not' inside it. Just use the positive auxiliary.
Link 'nor' to the auxiliary verb. Say 'nor-did-I' as if it's one word.
発音
Stress on 'Nor'
In speech, the word 'nor' is often slightly stressed to signal the addition of a new point.
Auxiliary Reduction
The auxiliary verb (do, does, did) is often spoken quickly and linked to the subject.
Rising-Falling
He didn't ↗call, nor did he ↘write.
The first clause rises slightly at the comma, and the 'nor' clause falls at the end to show completion.
暗記しよう
記憶術
NOR stands for 'Negative, Order Reverse'.
視覚的連想
Imagine a mirror placed after the comma. The subject and the helping verb look at the mirror and see themselves swapped on the other side.
Rhyme
When 'nor' begins the second part, flip the verb to make it smart!
Story
A detective named Nor always finds two clues. If the first clue is 'He didn't do it,' the second clue must be flipped: 'Nor did his friend.' He never says 'not' twice because he's too efficient.
Word Web
チャレンジ
Write three things you didn't do yesterday using 'nor' inversion (e.g., 'I didn't cook, nor did I clean').
文化メモ
Nor inversion is a staple of academic writing. Using it correctly can significantly improve the 'academic tone' score in essays.
In some British dialects, 'nor' is used more frequently in casual speech than in American English, though inversion is still the standard rule.
Contracts use 'nor' to ensure that multiple conditions are clearly negated, leaving no room for ambiguity.
Derived from Middle English 'nother', which was a contraction of 'ne' (not) and 'other'.

What is a food you don't like, and what is another food you also don't like?
Think of a famous person you don't admire. What are two things they haven't done well?

よくある質問 (8)
No. 'Nor' is a coordinating conjunction that requires a negative context to follow. If the first sentence is positive, use 'and' or 'but'.
Not exactly. 'Neither' is often used as an adjective or at the start of a pair. 'Nor' is the conjunction that links the second negative idea.
It is a rhetorical device in English called 'negative inversion'. It helps emphasize the negation and is a standard rule for the word 'nor'.
No, that is grammatically incorrect. You must say `nor do I`. The auxiliary must come before the subject.
Mostly, yes. In casual speech, people usually say 'and I don't either'. However, 'nor' is not 'wrong' in speech; it just sounds more educated.
Yes, when 'nor' is joining two independent clauses (full sentences), a comma is typically used before it.
If it's a simple tense like 'I don't like', the auxiliary is 'do/does'. If it's 'I wasn't', the auxiliary is 'was'. You must always find or provide an auxiliary.
Yes! 'I never saw him, nor did I want to.' 'Never' provides the negative context needed for 'nor'.
