Etymology
Origin of aghast
1225–75; Middle English agast frightened, past participle of agasten, equivalent to a- a- 3 + gasten, Old English gǣstan to frighten, earlier *gāstjan < Germanic causative *gaistjan; see ghost
Explanation
Would you be aghast, or shocked, to find out that your friends believe in ghosts, or would you share their frightened, or aghast, looks when a floating white being hovers over the campfire? Aghast comes from Old English gasten, "frighten," which comes in turn from gāst, "ghost." If you've seen a look of absolute shock or terror on someone's face — like when your mom (or dad) sees a mouse — you can describe the look with the adjective aghast. If someone says "You should have seen the look on your face!" after sneaking up on you, you probably looked aghast yourself. "Boo!"
