ennoble

The word 'ennoble' entered English in the late 15th century from the Old French ennoblir, which itself was built from the Latin elements in- (a causative prefix) and nobilis. The Latin nobilis originally meant "knowable, well-known," from the root gnoscere (to know), as aristocratic families were the prominent, known families in society. Over time, this association with high social rank blended with ideals of moral excellence. Thus, the literal construction "to cause to be noble" perfectly captures both the historical act of granting a noble title and the figurative act of elevating in dignity or character.
