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.

Ludwig's WRAP-UP

In summary, while the phrase "is but not" appears frequently in various contexts, Ludwig AI flags it as grammatically incorrect when used in isolation. It serves to introduce a contrast or qualification to a preceding statement. To ensure clarity and grammatical correctness, "is but not" should always be integrated into a complete sentence. 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.

FAQs

How can I correctly use the phrase "is but not" in a sentence?

The phrase "is but not" should always be part of a larger sentence structure to be grammatically correct. For example, you can say, "The movie is entertaining, but not very original" or "He is talented, but not always reliable."

What are some alternatives to "is but not" that I can use?

Depending on the context, you can use phrases like "is however not", "is though not", or "is yet not". These alternatives provide similar contrasting meanings while maintaining better grammatical structure.

Is it grammatically correct to start a sentence with "is but not"?

No, it is not grammatically correct to start a sentence with "is but not". This phrase requires a preceding clause to make sense and be grammatically sound. Starting a sentence this way results in a sentence fragment.

How does the meaning change when using "is however not" instead of "is but not"?

Using "is however not" instead of "is but not" adds a stronger emphasis to the contrast. "However" signals a more significant divergence or qualification than a simple "but".
