A “charm” may be an object believed to bring good luck, a small decorative item, or an appealing quality. “Works like a charm” means something works perfectly or as intended; “charming” describes a person or thing that attracts or pleases others.

Cultural note: A lucky charm is a matter of personal belief or tradition; do not present it as a guarantee of results. “Charming” can be praise, but context and tone matter, particularly when describing someone’s behavior.

Keep exploringSome words have literal, cultural, and figurative meanings. Practise using context to tell whether “charm” refers to luck, jewelry, or an appealing quality.
