astounding
UK: əˈstaʊndɪŋ | US: əˈstaʊndɪŋ
adj. causing astonishment or amazement; extremely surprising or impressive
The word "astounding" derives from the verb "astound," which originated in the late 16th century from the Middle English "astounen" (to stun or bewilder). "Astound" itself combines the prefix "a-" (intensifying) + "stound" (an Old English term for a moment of shock or pain). Over time, "astound" evolved to mean overwhelming surprise, and the suffix "-ing" was added to form the adjective, emphasizing a state of causing amazement.
