Common error
Avoid assuming that the audience understands the group you are referring to. Always provide enough context so the reader knows exactly who or what is being excluded by "not one of".

FAQs
How can I use "not one of" in a sentence?
Use "not one of" to indicate that someone or something does not belong to a particular group. For example: "He is "not one of" the invited guests".
What's the difference between "none of" and "not one of"?
"None of" and "not one of" are often interchangeable, but "not one of" emphasizes the individual exclusion from a group while "none of" focuses on the group as a whole. For example: "None of the students passed the exam" versus "Not one of the students passed the exam".
What can I say instead of "not one of"?
You can use alternatives like "no member of", "not included in", or "none among" depending on the context.
Is it correct to say "not one of them are" instead of "not one of them is"?
While grammatically, "is" is more correct because "one" is singular, "not one of them are" is sometimes used colloquially, particularly when emphasizing the collective aspect of "them". However, using "is" maintains formal correctness.
