waste: [12] The etymological notions underlying waste are ‘emptiness’ and ‘desolation’. Its main modern sense, ‘squander’, is a comparatively recent development, first recorded in English in the 14th century. Its ultimate source is Latin vāstus ‘empty’, which has also given English devastate and vast. From this was formed the verb vāstāre ‘devastate, lay waste’, which passed into English via Old Northern French waster. The derivative wastrel dates from the 16th century. => devastate, vast[waste etymology, waste origin, 英语词源]
