Expert writing Tips
Best practice
Avoid using "is but not" as a standalone phrase. Ensure it's part of a complete sentence for grammatical correctness. For example, "The idea is interesting, but not practical."
Common error
Do not use "is but not" as a fragment. Always ensure it's connected to a main clause to form a complete thought. A common mistake is using it as a short, choppy response, which lacks clarity and grammatical integrity.

News & Media sources show a greater prevalence of its use, though it is not common in formal writing. Alternatives such as ""is however not"" and ""is though not"" can offer more grammatically sound alternatives while maintaining a similar meaning.
