Imagining is the act of making mental pictures or scenarios. It's like having a movie playing inside your head.
When we talk about imagining, we often mean using our imagination to think about something that isn't real yet, but could be. For example, when you're planning a trip to a new country, you might start imagining what the food will taste like, how the cities look, or even what language people will speak there. You can also imagine different futures for yourself or others - maybe you'll become a famous artist, or your best friend will get married someday. People often use their imaginations when they're reading a book or watching a movie to think about what would happen if they were in the story themselves. Sometimes imagining is just a way to relax and let your mind wander, without worrying too much about reality.
Something imagined; a figment of the imagination.
