sur·priser n.
sur·prising·ly adv.

Synonyms: surprise, astonish, amaze, astound, dumbfound, flabbergast
These verbs mean to affect a person strongly as being unexpected or unusual. To surprise is to fill with often sudden wonder or disbelief as being unanticipated or out of the ordinary: "Never tell people how to do things. Tell them what to do and they will surprise you with their ingenuity" (George S. Patton).
Astonish suggests overwhelming surprise: The sight of such an enormous crowd astonished us. Amaze implies astonishment and often bewilderment: The violinist's virtuosity has amazed audiences all over the world. Astound connotes shock, as from something unprecedented in one's experience: We were astounded at the beauty of the mountains. Dumbfound adds to astound the suggestion of perplexity and often speechlessness: His question dumbfounded me, and I could not respond. Flabbergast is used as a more colorful equivalent of astound, astonish, or amaze: "He was utterly flabbergasted by the accusation and for a few moments he was quite unable to reply" (Alexander McCall Smith).
