Have you ever heard someone say “Neither do I” and wondered whether “Nor do I” would work just as well? These two expressions often confuse English learners and even native speakers because they seem to mean the same thing.
The good news is that both phrases are correct in the right context. However, understanding when to use nor do I or neither do I can make your English sound more natural and grammatically accurate. In this guide, you’ll learn their meanings, differences, examples, common mistakes, and practical usage tips.
Quick Answer
“Neither do I” and “Nor do I” are both used to agree with a negative statement.
Example:
- Person A: “I don’t like spicy food.”
- Person B: “Neither do I.”
- Person B: “Nor do I.”
In modern English, “Neither do I” is much more common and natural in everyday conversation. “Nor do I” is usually used after a sentence containing nor or in more formal writing.
What Does “Neither Do I” Mean?
The phrase “Neither do I” means:
“I also do not.”
It is used when you want to agree with someone who has made a negative statement.
Examples
- “I don’t watch horror movies.”
- “Neither do I.”
- “I can’t swim.”
- “Neither can I.”
- “I wasn’t invited.”
- “Neither was I.”
In each example, the second speaker shares the same negative experience or opinion.
Why It Is So Common
Native English speakers frequently use “Neither do I” because it sounds natural, polite, and concise. Instead of repeating the entire negative sentence, the phrase expresses agreement in just three words.
What Does “Nor Do I” Mean?
“Nor do I” also means:
“I do not either.”
It expresses agreement with a negative statement, just like “Neither do I.”
Examples
- “I don’t enjoy loud parties.”
- “Nor do I.”
- “She doesn’t eat meat.”
- “Nor do I.”
- “They weren’t ready.”
- “Nor were we.”
Although grammatically correct, “Nor do I” often sounds more formal or literary than “Neither do I.”
Nor Do I or Neither Do I: What’s the Difference?
The main difference is not meaning but usage and style.
| Feature | Neither Do I | Nor Do I |
| Meaning | I don’t either | I don’t either |
| Common in conversation | Yes | Less common |
| Formality | Neutral | More formal |
| Everyday speech | Very common | Less frequent |
| Writing | Common | Often used in formal writing |
| Sounds natural to most speakers | Yes | Sometimes more literary |
In most daily situations, “Neither do I” is the safer and more natural choice.
When to Use “Neither Do I”
Use “Neither do I” when responding to a negative statement and showing agreement.
Examples
- “I don’t drink coffee.”
- “Neither do I.”
- “I can’t understand this lesson.”
- “Neither can I.”
- “I wasn’t expecting that.”
- “Neither was I.”
Common Situations
You can use it when discussing:
- Preferences
- Opinions
- Experiences
- Abilities
- Feelings
Because it is versatile and widely accepted, it appears frequently in spoken and written English.
When to Use “Nor Do I”
Use “Nor do I” when:
- Responding to a negative statement in a formal style.
- Continuing a sentence that already contains nor.
- Writing in a literary or professional context.
Examples
- “I don’t support the proposal.”
- “Nor do I.”
- “She didn’t call, nor did she send a message.”
- “He wasn’t informed, nor was his manager.”
In these situations, nor creates a smoother grammatical connection.
Grammar Rule Behind Both Expressions
Both phrases use subject-auxiliary inversion, which means the helping verb comes before the subject.
Structure
Neither/Nor + Auxiliary Verb + Subject
Examples
- Neither do I.
- Neither can she.
- Neither was he.
- Nor do we.
- Nor have they.
- Nor will I.
The auxiliary verb must match the tense and form used in the original statement.
Examples
Original statement:
- “I don’t like tea.”
- “Neither do I.”
Original statement:
- “I can’t drive.”
- “Neither can I.”
Original statement:
- “I wasn’t aware.”
- “Neither was I.”
Using the correct auxiliary verb is essential for grammatical accuracy.
Common Mistakes to Avoid
Many learners misuse these expressions. Here are some frequent errors.
Mistake 1: Using a Double Negative
❌ I don’t like it either neither.
✅ I don’t like it either.
✅ Neither do I.
Avoid combining multiple negative forms unnecessarily.
Mistake 2: Wrong Word Order
❌ Neither I do.
✅ Neither do I.
The auxiliary verb must come before the subject.
Mistake 3: Using the Wrong Auxiliary Verb
❌ I can’t swim.
Neither do I.
✅ I can’t swim.
Neither can I.
Match the auxiliary verb from the original sentence.
Mistake 4: Mixing Positive and Negative Agreement
❌ I like pizza.
Neither do I.
✅ I like pizza.
So do I.
Use so do I for positive agreement and neither do I for negative agreement.
Neither Do I vs So Do I
Understanding this distinction is important.
| Expression | Purpose |
| So do I | Agree with a positive statement |
| Neither do I | Agree with a negative statement |
| Nor do I | Agree with a negative statement |
Examples
Positive:
- “I love traveling.”
- “So do I.”
Negative:
- “I don’t enjoy long flights.”
- “Neither do I.”
Negative:
- “I don’t enjoy long flights.”

American vs British English
There is no major grammatical difference between American and British English regarding these expressions.
However, usage patterns vary slightly.
American English
