neither X or Y (neither X nor Y)

Use neither ... nor to exclude two (or more) items: "Neither John nor Mary" is correct; "Neither John or Mary" is not. Below: a short rule, clear examples you can copy, ready rewrites, verb-agreement notes, quick proofreading tips, and related pitfalls to watch for.

Quick answer

After neither, use nor: Neither John nor Mary (not Neither John or Mary).

• "Neither" is negative; pair it with the negative conjunction "nor."
• Quick fix: change "or" → "nor" or rephrase the sentence to remove ambiguity.
• If subjects are long or mixed, a rewrite often improves flow and agreement ("Both A and B were absent").

Is "Neither John or" correct?

In standard written English, "Neither John or" is nonstandard. It appears in speech, but in formal, academic, or professional writing you should use "neither ... nor" or a clear paraphrase.

• Readers usually treat "neither ... or" as a mistake or a typo.
• Use the standard form to avoid distracting your audience.

Why "nor" after "neither"?

"Neither" introduces a negative choice; "nor" continues that negative structure and preserves parallelism. Using "or" breaks that pattern and can muddy the meaning.

Verb agreement note: when subjects are joined by neither ... nor, the verb usually agrees with the noun closest to it (proximity rule): "Neither the teacher nor the students were ready." If that causes awkwardness, rewrite the sentence.

How to fix your own sentence

Don't just swap words-read the sentence aloud and check tone and agreement. If replacing "or" with "nor" feels awkward, rewrite the sentence for clarity.

• Step 1: Identify the intended meaning.
• Step 2: Insert "neither ... nor" or rephrase.
• Step 3: Check verb agreement and flow.

• Rewrite:
  Original: The plan is neither viable or approved.
  Rewrite: The plan is neither viable nor approved.
• Rewrite:
  Original: The assignment feels neither fair or achievable.
  Rewrite: The assignment feels neither fair nor achievable.
• Rewrite:
  Original: Is that meeting neither today or tomorrow?
  Rewrite: Is that meeting neither today nor tomorrow?

A simple memory trick

Link form to meaning: picture "neither ... nor" as a single unit that signals exclusion. When you hear the negative start, expect another negative conjunction to follow.

• Train by scanning past drafts for "neither" and fixing the following word.
• Practice with common pairs: neither/nor, either/or, not only/but also.

Similar mistakes to watch for

Once a writer slips on one conjunction, nearby problems often follow. Scan for related issues like spacing, hyphenation, and verb forms.

• Split or fused words (e.g., "all right" vs "alright").
• Hyphen confusion in compound modifiers.
• Verb-form and agreement errors after compound subjects.
