noun词源
early 16th cent. （as emprowe or improwe）： from Anglo-Norman French emprower （based on Old French prou 'profit'， ultimately from Latin prodest 'is of advantage'）; -owe was changed to -ove under the influence of PROVE. The original sense was 'make a profit， increase the value of'; subsequently 'make greater in amount or degree'.
