Definition of unforeseeable. : not able to be reasonably anticipated or expected : not foreseeable an unforeseeable event/problem.
Something unforeseen is something that could not be predicted and was not expected. It's a surprise. If something was foreseen, you saw it coming and it wasn't a surprise. Something unforeseen is the opposite: no one saw it coming. Accidents are usually unforeseen events: no one expects to get in a car or bike accident on a given day. Winning the lottery, since it's so unlikely, would be an unforeseen event.
