Etymology
Origin of improve
First recorded in 1425–75; late Middle English improuen, emprouen from Anglo-French emprouer “to turn (something) into profit,” derivative of phrase en prou “into profit,” equivalent to en ( en- 1 ) + prou, Old French prou, preu from Late Latin prōde (est), by reanalysis of Latin prōdest “(it) is beneficial, of use,” with prōde taken as a neuter noun ( proud ); the sound v was made by association with prove, approve
