Expert writing Tips
Best practice
Avoid repeating "one" directly after "but" as it often creates redundancy. Review your sentence to ensure clarity and conciseness by removing the extra word.
Common error
Ensure that you're not unintentionally repeating words. In most contexts, "but one" is sufficient. Repeating "one" immediately after "but" adds no additional meaning and can make your writing appear less polished.
