Frequently Asked Questions

1. Can I use ‘ameliorate’ instead of ‘improve’?

Yes, but only in very formal academic writing. “Ameliorate” means to make something bad better. For example: “The policy aims to ameliorate poverty.” In most situations, “improve” or “enhance” is clearer and more natural.

2. What is the difference between ‘improve’ and ‘better’ as verbs?

“Improve” is slightly more formal and general. “Better” as a verb is more direct and informal. For example: “I want to improve my grades” (standard) vs. “I want to better my grades” (conversational). Both are correct.

3. Is ‘progress’ a good synonym for ‘improve’?

No, “progress” is usually a noun, not a verb. You can say “make progress” but not “progress something.” For example: “The project is making progress” (correct) vs. “We need to progress the project” (incorrect). Use “advance” instead: “We need to advance the project.”

4. When should I avoid using ‘improve’ altogether?

Avoid “improve” when you need to be specific about the type of change. If you are writing a research paper, a business report, or a cover letter, choose a more precise word like “enhance,” “strengthen,” or “refine.” In everyday conversation, “improve” is usually fine.
