No one or Noone: Which Is Correct?
Updated · Which One Is Correct editorial team

Quick answer: When asking about the existence of people, you must use "no one" as two separate words to be grammatically correct. While some prefer the hyphenated version in British English, the one-word spelling "noone" is a common misspelling that should be avoided in standard writing. Understanding this distinction ensures your text remains clear and professional.
The Short Answer
No one written as two words is the standard correct form, though no-one serves as an accepted variant in British English. You should never use the single word noone as it is a misspelling.
People often confuse these forms because the words sound identical when spoken. The visual difference between two words or a hyphen versus a single block of letters is crucial for correct literacy.

| no one | Correct | Standard American and international English. |
| no-one | Accepted | Formal British English usage only. |
| noone | Incorrect | Never, as this is a spelling error. |
| type | Interjection | Always used as an indefinite pronoun. |

A Quick Test You Can Use

If you replace the phrase with someone or everybody, the sentence structure remains the same, proving that the two-word version is the standard choice.

Frequently Asked Questions
When can I use no-one?
You may use no-one with a hyphen only in British English. It acts as an acceptable variant of the two-word form no one. This usage is rare in American English and often considered outdated.
Why do people write noone?
People often type noone because they hear the word as a single unit. Since there is no space between the sounds when spoken, they assume the spelling should match, but English grammar requires two distinct words.
Is no one singular or plural?
No one is grammatically singular even though it implies a group of people. Verbs following it must be singular, for example, saying he is not saying they are.
