imaginative
Able to think of new, creative ideas and pictures.
Imaginative means having a strong ability to form new and original ideas, images, or possibilities in your mind. An imaginative person doesn't just see what's already there: they envision what could be, creating mental pictures of things that don't yet exist.
When a child builds an elaborate fort out of couch cushions and declares it a castle on Mars, that's imaginative thinking. When an inventor sketches out a machine that nobody has built before, she's being imaginative. Writers are imaginative when they create entire worlds with their own rules, creatures, and histories.
Imaginative people often ask “What if?” questions. What if animals could talk? What if you could travel through time? What if we solved this problem in a completely different way? This quality helps artists create paintings that make you see the world differently, helps scientists develop breakthrough theories, and helps engineers design solutions to problems nobody has solved before.
Being imaginative is different from just daydreaming randomly. It means actively using your mind to generate creative possibilities and new combinations of ideas. The most imaginative thinkers take familiar elements and recombine them in surprising ways, like someone who imagines a story about a school for young wizards, or an architect who designs a building shaped like a sailing ship.
