An clever person is someone who thinks quickly and comes up with good ideas.
When we say someone is clever, we usually mean they are smart or resourceful. We might praise a child for being clever if they figure out how to solve a tricky problem on their own. A clever person is often good at thinking on their feet and coming up with creative solutions to unexpected situations.
