Extremely surprising or shocking in a way that leaves you speechless.
The present participle form of astony, formed by adding -ing to the verb. It preserves the archaic verb form while creating an adjective meaning 'causing astonishment or shock.'
This is the kind of word Shakespeare might have used—it means something is so surprising it actually stuns you into silence, which is much more dramatic than just 'amazing.'
