语源
  1. Middle English whennes, from earlier whenne (from Old English hwanon, of Germanic origin) + -s (later respelled -ce to denote the unvoiced sound)
用法
  1. Strictly speaking, whence means ‘from what place’, as in whence did you come? Thus, the preposition from in from whence did you come? is redundant and its use is considered incorrect by some. The use with from is very common, though (occurring in more than 20 per cent of citations for whence in the British National Corpus), and has been used by reputable writers since the 14th century. It is now broadly accepted in standard English
