An intellect is someone's ability to think deeply and solve problems.
When we talk about someone having high intellect, we usually mean they're smart and can learn quickly. We might say "She has a great intellect" when we mean she's really good at understanding complicated ideas or finding creative solutions. This could be because she did well in school, is great with puzzles, or just seems to figure things out easily. Some people use the word intellect to talk about how smart someone is naturally - like a genius.
(uncountable) The faculty of thinking, judging, abstract reasoning, and conceptual understanding; the cognitive faculty.
Example: Intellect is one of man's greatest powers.
