| Usage notes | Use 'expertise' in professional or academic contexts. It sounds formal, so avoid it in casual conversations. Saying someone has expertise conveys respect for their knowledge. | Use 'knowledge' in both formal and casual contexts. It's appropriate in academic settings, discussions, and everyday conversations, but avoid using it in overly casual slang situations. | Use 'skill' to talk about abilities in various contexts, from sports to arts.
