What does astonished mean?
Astonished describes the state of being filled with sudden, overwhelming surprise or wonder, typically in reaction to something entirely unexpected. It functions as an adjective — historically the past participle of the verb astonish — and appears most often after linking verbs: she was astonished, they seemed astonished, he stood astonished. The word conveys a stronger reaction than mere surprise but stops short of outright disbelief, placing it between surprised and astounded on the spectrum of amazement. Common collocations include utterly astonished, visibly astonished, and astonished to learn or discover. Its tone is neutral to positive, making it suitable for both formal writing and everyday speech. What makes the word especially interesting is its origin: it derives ultimately from the Latin tonare, meaning to thunder, so to be astonished is, etymologically speaking, to be struck as if by thunder. This vivid history gives the word a dramatic force that modern usage still preserves.
adjectiveFilled with sudden great surprise or wonder; greatly amazed by something unexpected.

"The scientists were astonished by the telescope's images of a galaxy forming just 400 million years after the Big Bang."
"'You mean you've never seen snow before?' he asked, visibly astonished."
Astonished literally traces back to Latin 'tonare' — to thunder — so when you say you're astonished, your ancestors would have said the news hit them like a clap of thunder.

Etymology of astonished
Astonished comes from the verb astonish, which entered English in the late Middle English period from the Old French estoner, itself derived from the Vulgar Latin extonare, formed from ex- ('out of') plus tonare ('to thunder'). The earliest sense was closer to 'to strike senseless' or 'to stun,' which survives in the related word stun, and it gradually shifted toward its modern meaning of overwhelming surprise. Words sharing this thunderous root include astound, stun, thunder, and detonate.
