      英文詞源


      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 ?tzen ‘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.)
