An improvement that makes something better, more attractive, or more valuable; the action of intensifying or increasing the quality of something.
From Old French enhaucier, meaning 'to raise up,' combining en- (in) and haut (high). The word evolved from the physical sense of raising something higher to the abstract sense of improving quality.
Enhancement makes things 'haute' (high-class) - the French root 'haut' means high, so enhancement lifts something up to a higher level of quality or value!
