| Usage notes | Used in both formal and informal contexts. Often refers to organizations or individuals in positions of power. | Use 'expert' to describe someone's high skill or knowledge in a specific area. More suitable in formal contexts, but can also be used informally when discussing hobbies or practical skills. | Use 'specialist' when referring to someone with expertise in a particular field, like medicine or technology. It's appropriate in both casual and professional contexts but may sound overly formal in everyday conversation. |
