Origin

Early 16th century (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’.
