n. an unexpected or astonishing event, fact, or feeling

The word "surprise" originates from Middle French surprendre ("to overtake"), composed of sur- (Latin super, meaning "over") and prendre ("to take"). It entered English in the 15th century with the sense of "unexpected seizure or attack." Over time, the meaning softened to emphasize the emotional reaction to the unexpected, retaining the core idea of "taking over" someone's expectations.
