rehearse: [13] To rehearse something is etymologically to ‘rake it over’. The word comes from Old French rehercer ‘repeat’, a compound verb based on hercer ‘harrow’. This was a derivative of the noun herce ‘large agricultural rake’, from which English gets hearse. At first in English too rehearse meant simply ‘say over again, repeat, recite’; not until the late 16th century did the modern theatrical meaning begin to emerge. => hearse[rehearse etymology, rehearse origin, 英语词源]
