Nor do I vs. Neither do I – Which is Correct?

Both “nor do I” and “neither do I” are grammatically correct and interchangeable phrases used to express agreement with a negative statement. They both serve to indicate that the speaker shares the same negative experience, feeling, or action as previously mentioned by another person. The choice between them often comes down to personal preference or stylistic variation.

Nor do I or Neither do I – Which is Correct?

In American English, both “nor do I” and “neither do I” are perfectly correct and convey the exact same meaning: agreement with a preceding negative statement. For instance, if someone says, “I don’t like broccoli,” you could respond with either “Nor do I” or “Neither do I” to express that you also dislike broccoli. These phrases are examples of negative agreement, where the auxiliary verb “do” (or “am,” “have,” etc.) inverts with the subject “I” after the negative conjunction.

The Best Trick to Remember the Difference

Since both phrases are correct and interchangeable, the trick isn’t in distinguishing correctness, but rather in recognizing their function. Think of them as two sides of the same coin for expressing negative agreement. Just as “me too” is a common way to express positive agreement, “nor do I” and “neither do I” are the standard ways to express negative agreement. If you can use “Me too” for positive, then you know you need “nor/neither do I” for negative.

Phrase	Part of Speech	Meaning	Example
Nor do I	Conjunction + Auxiliary Verb + Pronoun	I also do not; I agree with the negative statement.	“I haven’t seen that movie.” “Nor do I.”
Neither do I	Determiner/Pronoun + Auxiliary Verb + Pronoun	I also do not; I agree with the negative statement.	“She can’t swim.” “Neither do I.”

How to Use Nor do I

“Nor do I” is a common and grammatically sound phrase used to express that the speaker shares a negative experience, opinion, or action with someone else. It functions as a concise way to agree with a negative statement. The structure typically involves “Nor” followed by an auxiliary verb (do, did, am, is, has, have, can, could, will, would, etc.) and then the subject pronoun (I, he, she, they, we, you). It is suitable for both formal and informal contexts.

Example 1: “I don’t think we have enough time to finish this project today.” “Nor do I. We should plan to continue tomorrow.”

Example 2: “He wasn’t happy with the outcome of the meeting.” “Nor was I; it felt quite unproductive.”

Example 3: “They haven’t received the new shipment yet.” “Nor have I heard any updates about it.”

Etymology of the phrase Nor do I

The phrase “nor do I” derives from the conjunction “nor,” which has Old English roots (from nā-hwæther, meaning “not either”). “Nor” itself serves to introduce a further negative statement or clause. When paired with an inverted auxiliary verb and pronoun, as in “nor do I,” it forms a standard idiomatic expression for negative agreement, emphasizing the shared negation.

How to Use Neither do I

“Neither do I” serves the exact same purpose and carries the same meaning as “nor do I.” It is used to indicate that the speaker also does not share a negative sentiment or action. Like “nor do I,” it employs an inverted word order with an auxiliary verb before the subject. This phrase is widely accepted and used across various registers of speech and writing, from casual conversations to more formal documents.

Example 1: “I can’t imagine living without coffee.” “Neither can I; it’s essential for my mornings.”

Example 2: “She didn’t understand the instructions.” “Neither did I, they were quite vague.”

Example 3: “We aren’t going to the party tonight.” “Neither are we; we have other plans.”

Etymology of the phrase Neither do I

The word “neither” comes from Old English nāwther or nāther, meaning “not either.” It functions as a determiner, pronoun, or conjunction. In the phrase “neither do I,” “neither” acts as a negative correlative or conjunction, introducing a statement of mutual negation. The construction with the inverted auxiliary verb and pronoun has been a standard grammatical form for centuries to express this specific type of agreement.

Related Concepts

Understanding a broader grammar concept often helps clarify the nuances of specific phrases like “nor do I” and “neither do I.”

• Negative Agreement: This is the grammatical concept behind “nor do I” and “neither do I.” It refers to the way speakers express that they share a negative sentiment or action with another person or statement. It often involves using negative conjunctions or adverbs with subject-verb inversion.
• Subject-Auxiliary Inversion: This is the grammatical structure at play. In standard English, the subject usually comes before the verb. However, in questions, certain conditional clauses, and expressions of agreement or disagreement (like “nor do I”), the auxiliary verb (do, have, be, can, etc.) comes before the subject.

Examples from Media and Literature

• In a dialogue from a contemporary novel: “I’m not sure I believe his story.” “Nor do I. It sounds far-fetched.”
• From a news report about public opinion: “Many residents don’t support the new zoning laws, and neither do I, as a council member.”
• In a movie script: Character A: “I never thought I’d see the day.” Character B: “Neither did I.”
• From a historical account: “The explorer had no idea what dangers lay ahead, and nor did his crew.”
• In a personal essay: “I couldn’t shake the feeling that something was wrong, and neither could my sister.”
