Common Mistakes When Using Synonyms for ‘improve’

Even advanced students make errors when choosing synonyms. Here are the most frequent mistakes and how to avoid them.

Mistake 1: Using ‘ameliorate’ in everyday conversation

Wrong: “I need to ameliorate my breakfast.”
Right: “I need to improve my breakfast.” or “I need to make a better breakfast.”

Mistake 2: Confusing ‘boost’ with long-term improvement

Wrong: “I want to boost my English level in one week.”
Right: “I want to boost my confidence in speaking English this week.”

Why: “Upgrade” implies replacing something, while skills are usually developed or strengthened.

Mistake 4: Overusing ‘enhance’ in every context

Wrong: “I want to enhance my grades.”
Right: “I want to raise my grades.” or “I want to improve my grades.”
Why: “Enhance” is best for adding quality or value, not for numerical increases like grades.
