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; thunder
