People often get confused about nor do I and neither do I because both are used to show agreement with a negative statement, and both can sound correct in everyday speech. The trouble is that they are not always interchangeable in every context, and the word order can change depending on the verb and subject. That matters in writing, speaking, exams, interviews, and professional communication, because even a small grammar mistake can make your English sound unnatural or less confident.
In simple terms, both expressions are used when you want to say that something negative also applies to you. For example, if someone says, “I don’t like tea,” you may reply, “Neither do I” or “Nor do I,” depending on the style and structure. This guide explains the difference clearly, with examples, tables, and easy rules so you can use both forms correctly.
Meaning of “Nor Do I” and “Neither Do I”
Both nor do I and neither do I are used to agree with a negative statement.
They mean:
- “I also do not…”
- “The same negative thing applies to me”
- “I agree with the negative idea”
Basic meaning
If someone says:
- I don’t smoke.
You can respond:
- Neither do I.
- Nor do I.
Both responses mean:
- I also do not smoke.
Simple comparison
| Phrase | Main meaning | Tone |
| neither do I | I also do not | common, natural, neutral |
| nor do I | I also do not | slightly formal, literary, or emphatic |
Quick idea
Use neither do I in most everyday situations.
Use nor do I when the style is a little more formal or when you want a stronger or more polished sound.
Examples
- She doesn’t want to go, and neither do I.
- He cannot drive, and nor can I.
- They did not agree, and neither did we.
Notice that nor is often used with inversion, just like neither in formal structures.
Correct Usage: When to Use Each Expression
The first thing to understand is that these expressions usually come after a negative statement.
Use “neither do I” when:
- you are agreeing with a negative statement
- you want a natural, common response
- you are speaking or writing in everyday English
Examples
- I don’t like mushrooms.
Neither do I. - She hasn’t finished the report.
Neither have I. - They won’t come to the meeting.
Neither will I.
Use “nor do I” when:
- you want a slightly more formal style
- you want to sound polished or emphatic
- the sentence structure already contains a negative idea and you want to continue it elegantly
Examples
- He was not invited, nor was I.
- She cannot attend, nor can I.
- They did not approve of the plan, nor did we.
Important note
In many cases, nor is more common in full sentence structures than as a short response.
For example:
- I don’t like the idea, nor do I enjoy the process.
This sounds fine in formal writing.
But as a short answer in conversation:
- I don’t like the idea.
Neither do I.
This is more natural.
Best practical rule
| Situation | Preferred choice |
| short spoken reply | neither do I |
| formal writing | nor do I / neither do I |
| negative addition in a sentence | nor often works well |
| casual conversation | neither do I |
Grammar Rules: Word Order and Agreement
This topic becomes easier once you understand the grammar pattern.
Both expressions usually use subject-auxiliary inversion. That means the helping verb comes before the subject.
Pattern with “neither do I”
Neither + auxiliary verb + subject
Examples:
- Neither do I.
- Neither can I.
- Neither have I.
- Neither will I.
Pattern with “nor do I”
Nor + auxiliary verb + subject
Examples:
- Nor do I.
- Nor can I.
- Nor have I.
- Nor will I.
Why the auxiliary verb changes
The auxiliary verb depends on the tense or modal verb in the original negative sentence.
| Original sentence | Correct reply |
| I don’t like coffee. | Neither do I. |
| She didn’t call me. | Neither did I. |
| We aren’t ready. | Neither are we. |
| He can’t swim. | Neither can I. |
| They won’t agree. | Neither will I. |
Grammar table: subject-verb order
| Negative sentence | Short agreement reply |
| I don’t know. | Neither do I. |
| She isn’t coming. | Neither is he. |
| They haven’t left. | Neither have we. |
| He can’t help. | Neither can I. |
Rule to remember
The helper verb in the answer should match the helper verb in the original sentence.
- don’t → do
- doesn’t → does
- didn’t → did
- can’t → can
- won’t → will
- isn’t → is
- hasn’t → has
Correct examples
- I don’t watch that show.
Neither do I. - She can’t attend.
Neither can I. - They haven’t finished.
Neither have we.
Incorrect examples
- I don’t watch that show.
Neither I do. ❌ - She can’t attend.
Nor I can. ❌ - They haven’t finished.
Neither do we. ❌
The word order matters. English does not usually allow free rearrangement here.
“Nor” vs “Neither”: Similar, But Not Identical
These two words are related, but they are not used exactly the same way.
“Neither”
Neither is commonly used in short responses and in paired negative structures.
Examples:
- Neither of the answers is correct.
- Neither John nor Mary called.
- Neither do I.
- Neither can we.
“Nor”
Nor often appears in more formal or literary writing, especially after a negative clause.
Examples:
- He did not call, nor did he explain why.
- She has never been late, nor has she ever complained.
- They did not agree, nor were they willing to discuss it.
Side-by-side comparison
| Word | Common use | Example |
| neither | short negative agreement, pair structures | Neither do I. |
| nor | continuation after a negative clause | He did not call, nor did he write. |
A useful distinction
- Neither often starts a short reply.
- Nor often joins two negative ideas in a sentence.
Examples in context
- I am not interested. Neither am I.
- I was not invited, nor was my brother.
Both are correct, but they feel slightly different in style.
British vs American English
This is one of those grammar points where both British and American English use the expressions, but the tone and frequency can vary a little.
General pattern
- Neither do I is widely used in both British and American English.
- Nor do I is also correct in both varieties, but it often sounds a bit more formal or careful.
- In casual speech, many native speakers prefer me neither, which is common but less formal.
Comparison table
| Expression | British English | American English | Formality |
| Neither do I | common | common | neutral |
| Nor do I | correct, slightly formal | correct, slightly formal | formal/polished |
| Me neither | common in speech | very common in speech | informal |
Examples
- I don’t like crowded places.
Neither do I.
Nor do I. - I can’t hear anything.
Neither can I. - I don’t want dessert.
Me neither.
This is common in conversation, but it is not the best choice in formal writing.
Practical advice
If you are writing:
- an essay
- a report
- an email to a client
- an exam answer
then neither do I or nor do I is the safer choice.
If you are speaking casually, me neither may sound more natural in informal conversation, though it is best to understand the grammar behind it.
Pronunciation
1Pronunciation is simple, but the stress can affect how natural your speech sounds,
Pronunciation guide
| Phrase | Approximate pronunciation |
| neither do I | NEE-ther do I / NYEE-ther do I |
| nor do I | nor do I |
In British English, neither is often pronounced /ˈnaɪðə/ or /ˈniːðə/ depending on accent. In American English, /ˈnaɪðər/ is common. Both are acceptable.
Say it naturally
- Neither do I

Common pronunciation issues
Some learners overemphasize the “th” sound or rush the phrase too quickly. Try speaking it slowly first:
- Neither do I
- Nor do I
Pronunciation tip
Keep the stress on the first part of the phrase, not on the final “I.”
- NEI-ther do I
- NOR do I

Common Mistakes Learners Make
This grammar point is easy once you learn the pattern, but certain mistakes appear again and again.
Mistake 1: Using the wrong word order
Incorrect:
- Neither I do
- Nor I do
Correct:
- Neither do I
- Nor do I
The auxiliary verb must come before the subject.
Mistake 2: Using the wrong auxiliary verb
Incorrect:
- I don’t like tea. Neither does I. ❌
Correct:
- I don’t like tea. Neither do I. ✅
Why? Because the subject is I, so the helper verb should be do.
Mistake 3: Mixing “neither” with a positive sentence
Incorrect:
- She likes coffee. Neither do I. ❌
Correct:
- She doesn’t like coffee. Neither do I. ✅
These expressions are used to agree with a negative statement.
Mistake 4: Using “nor do I” in every situation
Incorrect:
- I don’t want to go. Nor do I.
This is not wrong, but it may sound less natural than Neither do I in casual conversation.
Better:
- I don’t want to go. Neither do I.
Mistake 5: Using “me neither” in formal writing
Incorrect in formal style:
- I do not agree with the decision. Me neither.
Better:
- I do not agree with the decision. Neither do I.
Mistake 6: Forgetting tense agreement
Incorrect:
- She didn’t call. Neither do I. ❌
Correct:
- She didn’t call. Neither did I. ✅
The auxiliary must match the tense of the original negative sentence.
Common mistake table
| Mistake | Correct form |
| Neither I do | Neither do I |
| Nor I do | Nor do I |
| Neither does I | Neither do I |
| Neither do I with a positive sentence | Use it after a negative statement |
| Me neither in formal writing | Neither do I |
