attackyoudaoicibaDictYouDict[attack 词源字典]
attack: [16] Attack reached English via French attaquer from Italian attaccare ‘attach, join’, which, like Old French atachier (source of English attach) was based on a hypothetical Germanic *stakōn (from which English gets stake). Phrases such as attaccare battaglia ‘join battle’ led to attaccare being used on its own to mean ‘attack’. Attach and attack are thus ‘doublets’ – that is, words with the same ultimate derivation but different meanings.
