astounding

Astounding is an adjective that describes something bewildering, like the astounding sight of a dog walking on two legs.

When something is astounding, you might find yourself unable to speak — after all, astounding comes from the Middle English word astouned, meaning "to stun." If you see something that's astounding, you might just stare and stare, speechless. Astounding also describes something so surprisingly impressive that it overwhelms, like the astounding news that you just won the lottery.
