No one, Noone, or No-one

No one, Noone, or No-one?

"No one," "noone," and "no-one" are often confused by writers, but the guidance is simple. Use "no one" (i.e., the two-word version). "No-one" and "noone" are spelling mistakes.

• No one. "No one" is the correct spelling. Even though "no body," "some body," and "some one" have become "nobody," "somebody," and "someone," "no one" has not followed this trend, most probably because "noone" looks unwieldy and would cause pronunciation errors.
• No-one. Outside North America, the hyphenated version "no-one" is occasionally used as an alternative spelling to "no one," but "no-one" remains about 20 times less common than "no one." In North America, most readers would consider the hyphenated version to be a spelling mistake.
• Noone "Noone" is never right. It's a spelling mistake.

The "no one" version is about 20 times more popular than the "no-one" version.

"No-one" Is Becoming More Common

Since the mid 1940s, the hyphenated version "no-one" has been growing more popular (particularly outside North America). Of note, some grammarians condone the hyphenated version, claiming it eliminates ambiguity in sentences like the following:

• No one person can overcome her power.
(This sentence causes a reading stutter. When readers reach "person," most readers would backtrack to read "no one" as "no single."
• No one can will work.
(Although contrived, this sentence is ambiguous. Is the subject "No one can" or "No one"?)

"No One" Is Always Right

There is some leniency on how to write "no one." Outside North America, using a hyphen is acceptable...just. If you've come to this page looking for justification for the hyphenated version, then I'm afraid you've failed. Here's the bottom line: Use "no one."

"Noone" Is Never Right

"Nobody," "somebody," "someone," and "nowhere" have become single words. "No one" has not. "Noone" is wrong.
This sign has the correct spelling of "no one."
