What does astonishing mean?
Astonishing describes something so surprising, remarkable, or unexpected that it provokes wonder or disbelief. Used almost exclusively as an adjective, it typically qualifies achievements, facts, quantities, or abilities — an astonishing recovery, an astonishing amount of money, an astonishing feat of engineering. The word carries a strongly positive connotation in most contexts, signaling admiration as much as mere surprise, though it can occasionally flag something shocking or dismaying, such as an astonishing degree of negligence. It derives ultimately from the Latin verb tonare, meaning 'to thunder,' via Old French, so its earliest sense involved being stunned as if deafened by a thunderclap — a vivid history that still echoes in its forceful tone today. Related forms include the verb astonish and the noun astonishment.

Astonishing traces back to the Latin word for thunder — to be astonished was originally to be struck senseless, as if by a bolt from the sky.

Etymology of astonishing
Astonishing comes from the verb astonish, which entered English in the early modern period via Middle English from Old French estoner ('to stun, daze'), itself derived from Vulgar Latin *extonare, formed from ex- ('out of') plus tonare ('to thunder'). The original sense was thus literally to be struck senseless as if by thunder, before softening over time into its modern meaning of causing great surprise. It shares this thunderous root with words such as stun and detonate.
