Dumbfound means to leave someone so astonished that they cannot find words to respond. It is a transitive verb, commonly used with a person or group as its object: a result may dumbfound scientists, or a visitor may be dumbfounded by a dramatic view.

Where does dumbfound come from?
Dumbfound is an early 18th-century English formation commonly understood as a blend of dumb and found, probably influenced by confound. Dumb comes from Old English and originally referred to a lack of speech or hearing. The precise development of the second element is less certain, but the compound clearly follows the expressive pattern of confound, meaning to confuse or overwhelm. Confound itself ultimately derives through Old French from Latin confundere, a verb meaning to mix together or confuse.
