etch 蚀刻

来自词根ed, 吃，词源同eat, edible.

etch: etch: [17] A line that has been etched has been literally ‘eaten’ away by acid or other corrosives. The word was borrowed from Dutch etsen, which in turn came from German ätzen ‘corrode, etch’. This can be traced back to a prehistoric Germanic *atjan ‘cause to eat, feed’, a relation of *etan ‘eat’ (from which English gets eat).
=> eat
etch (v.): 1630s, "to engrave by eating away the surface of with acids," from Dutch etsen, from German ätzen "to etch," from Old High German azzon "give to eat; cause to bite, feed," from Proto-Germanic *atjanan, causative of *etanan "eat" (see eat). Related: Etched; etching. The Etch A Sketch drawing toy was introduced 1960 by Ohio Art Company.
