Etymology
Origin of astonish
First recorded in 1525–35; Middle English astonyen, astonen, probably from unattested dialectal Old French astoner, Old French estoner, from unattested Vulgar Latin extonāre, for Latin attonāre “to strike with lightning,” equivalent to ex- ex- 1, at- at- + tonāre “to thunder”; extended by -ish 2, perhaps reflecting unattested Anglo-French astonir, from dialectal Old French; see thunder
Explanation
Things that might astonish you: the discovery of life on another planet, a death-defying performance, and the number of dinosaurs a six-year old child can name. To astonish is to amaze and astound. Remember that astonish means more than surprised. It carries with it a feeling of being truly impressed. Astonish derives from the Latin tonare 'thunder.' When you are astonished, you're thunderstruck. If you plan to astonish someone, you might say before hand, "Wait until you see this. It's going to knock your socks off."
