the word 'thunderstruck' is a transparent english compound formed from two native germanic elements. its literal, archaic meaning is 'hit by a thunderbolt,' a concept with deep roots in indo-european mythology where thunder was seen as a weapon of the gods. the figurative sense of being 'struck with amazement or terror' as if by a divine force emerged naturally from this powerful physical image. over time, the physical meaning receded, and the word solidified in modern english primarily to describe a state of profound shock or astonishment, perfectly preserving the metaphorical impact of its original components.

Structure: thunder + struck thunder: from old english 'þunor', of germanic origin, related to dutch 'donder' and german 'donner'. the noun refers to the loud noise that follows a lightning flash. struck: past participle of the verb 'strike', from old english 'strīcan', meaning to go, move, or hit sharply. in this compound, it means 'hit' or 'affected by'.
