“Neither do I” is the natural, everyday way to agree with a negative statement. “Nor do I” is also correct, but it sounds more formal and literary.
In most conversations, native speakers prefer “neither do I.” “Nor do I” is more common in formal writing or when linking two negative ideas within the same sentence. Both express the same meaning — the difference is primarily one of tone and style.
Both are correct. The difference is formality, context, and how naturally each one lands on the ear.
What Do “Neither Do I” and “Nor Do I” Actually Mean?
Both phrases serve the same purpose — they allow a speaker or writer to agree with a negative statement made by someone else. They are negative agreement expressions — the opposite of saying “So do I” in response to a positive statement.
Someone says: “I don’t enjoy early mornings.” You respond: “Neither do I.” or “Nor do I.“
Both responses are grammatically valid. But they feel different — and knowing why helps you choose the right one every time.
What Does “Neither Do I” Mean?
“Neither do I” is the most natural, widely accepted, and commonly used way to agree with a negative statement in everyday English. It functions as a short-form negative agreement — signaling that whatever the speaker just said does not apply to you either.
Example: “I don’t drink coffee.” — “Neither do I — I switched to tea years ago.”
The word “neither” comes from Old English nahwæther — meaning “not either of two.” In modern English it acts as a determiner, pronoun, and adverb — and in the construction “neither do I,” it functions as a negative adverb that inverts the subject and auxiliary verb, just like so does in positive agreement.
Common uses of “neither do I” in conversation:
- “I don’t like crowded places.” — “Neither do I — I always avoid rush hour.”
- “I haven’t seen that film.” — “Neither have I, but everyone keeps recommending it.”
- “I can’t work in complete silence.” — “Neither can I — I always need background noise.”
“Neither do I” Across Different Verb Forms
The auxiliary verb in “neither do I” always mirrors the auxiliary verb in the original statement. “Do” is used only when the original statement uses do/does/did. Every other auxiliary verb replaces it accordingly.
What Does “Nor Do I” Mean?
“Nor do I” carries exactly the same meaning as “neither do I” — but it is more formal, literary, and slightly old-fashioned in tone. It appears more frequently in written English, formal speech, and as a connector between two negative clauses in a single sentence.
Example: “I don’t enjoy small talk, nor do I find it easy to initiate conversation.”
The word “nor” comes from Middle English — a contraction of ne (not) and or. It has always been associated with the neither…nor construction in formal grammar. Used alone as “nor do I,” it functions as a negative coordinating conjunction — linking the previous negative thought to a new one, or simply echoing it in agreement.
Common uses of “nor do I” in formal writing:
- “The policy does not serve the public interest, nor do I believe it was designed to.”
- “She has never apologized for her conduct, nor do I expect she ever will.”
- “The evidence does not support that conclusion, nor do I find the reasoning persuasive.”
“Nor do I” Across Different Verb Forms
Like “neither do I,” the auxiliary verb in “nor do I” mirrors the auxiliary verb in the original statement. The grammatical inversion rule is identical — only the tone and formality differ.
Neither Do I vs. Nor Do I — Key Differences That Actually Matter
Both phrases are grammatically correct. But choosing between them affects the tone, register, and flow of your writing and speech — and in certain sentence structures, only one of them works correctly.
Neither Do I vs Nor Do I — Formality and Natural Sound
When “Nor Do I” Works Better Than “Neither Do I”
“Nor do I” is the stronger choice in one specific situation — when it is connecting two negative clauses within the same sentence. In this role it functions as a coordinating conjunction, linking the negative thought that came before it to a new negative thought.
“She does not trust the process, nor do I believe the outcome will be fair.”
Using “neither do I” in this position is grammatically acceptable — but “nor do I” flows more naturally and reads as more structurally precise in formal writing.
“Neither do I” works better as a standalone response in conversation — agreeing with what someone else just said without adding a new clause.

The “Me Neither” and “Me Either” Alternatives
In casual American English, both “neither do I” and “nor do I” are frequently replaced by much shorter informal alternatives.
“Me neither” is the most popular and widely accepted casual form. It is conversational, warm, and immediately understood.
“Me either” is a common spoken American English variation — though some grammarians consider it less standard than “me neither.” In formal writing, neither of these casual forms is appropriate.

Same Meaning, Different Register — How the Choice Signals Tone
Casual: “I don’t enjoy formal dinners.” — “Neither do I — they always feel so stiff.”
Formal: “I do not find formal occasions particularly comfortable, nor do I feel they bring out the best in most people.”
Same sentiment. Same negative agreement. But “neither do I” feels like a conversation between friends — and “nor do I” reads like a sentence from an essay or a formal speech.

Frequently Asked Questions
Is it you all or y’all?
“You all” is the grammatically standard form — two words used to address a group of people. “Y’all” is a contracted form of “you all” widely used in Southern American English and increasingly common in casual American speech. In formal writing, use “you all.” In casual and regional writing, “y’all” is natural and widely understood.
When should I use neither and nor?
Use “neither” when introducing a negative choice between two things — often paired with “nor” in the neither…nor construction: “Neither the manager nor the team was informed.” Use “nor” alone when connecting a second negative clause to a previous negative statement — “She did not attend, nor did she send an explanation.” In everyday agreement, use “neither do I” for speech and “nor do I” for formal writing.
What is the meaning of “nor do I”?
“Nor do I” means “I also do not” — it agrees with a negative statement made by someone else or extends a negative thought in the same sentence. It is the more formal equivalent of “neither do I.” Example: “The proposal was not approved, nor do I expect it to be reconsidered.”
When should I use “neither do I”?
Use “neither do I” whenever you want to agree with a negative statement in natural, everyday English. It is the most common and conversational choice — appropriate in both speech and writing. Use it as a standalone response: “I don’t enjoy long meetings.” — “Neither do I.“ For formal written English or when connecting two negative clauses in one sentence, consider “nor do I” instead.
Conclusion
“Neither do I” and “nor do I” mean the same thing — but they belong in different contexts. “Neither do I” is the natural, conversational choice for everyday agreement. “Nor do I” is the formal, literary choice — strongest when connecting two negative clauses in a single sentence.
Match your auxiliary verb to the original statement, pick the phrase that fits your register, and remember that in casual speech “me neither” is always waiting as the quickest and most natural option of all.
