An idea that isn't connected to any real, physical thing — a general concept rather than something you can touch, like freedom or justice. It's also the process of leaving out small details to focus on the big general idea, used in art (an abstraction of a landscape, using only shapes) and in fields like computer science. It can also describe being lost in thought, not paying attention to what's around you.
