shift [shift 词源字典]: shift: [OE] Old English sciftan meant ‘arrange’ (it came from a prehistoric Germanic base *skip-, which also produced German schichten ‘arrange in layers, pile up’, and traces of its original meaning survive in make-shift [16], denoting something arranged or contrived for lack of anything better). Its modern meaning ‘move’ emerged in the 14th century, via an intermediate ‘change’. The notion of ‘change’ underlies the use of the noun shift for ‘woman’s slip’, which evolved from an earlier ‘change of clothing’, and also its use for a ‘particular working period’, marked by a ‘change’ of workers at beginning and end.
