word
Definition
A genius is a person with extremely great natural ability, especially in thinking, creating, or solving difficult problems. It can also be used informally for someone who has a very clever idea or does something surprisingly smart.
Usage & Nuances
Often very positive and strong, so don't use it for ordinary intelligence. Common patterns: 'a musical genius', 'a genius at math', 'a stroke of genius'. In casual speech, people also say 'You're a genius' for a clever practical idea, sometimes sincerely and sometimes jokingly.
