When you foresee something, you predict or realistically envision it happening. Did you foresee your team winning the playoffs, or were you surprised?
Think of foresee as “to see before.” Prophets in literature are able to foresee events that come to pass; in Greek mythology Tiresias is known for his ability to foresee the future. But foresee is not always linked to a supernatural sense. Regular people can foresee events by imagining them taking place — and sometimes we use this as a way of prevention. If you foresee yourself failing geometry if you don’t study more, you will probably hit the books.
