c.1300, clarte “brightness,” from Old French clarté “clarity, brightness,” from Latin claritas “brightness, splendor,” also, of sounds, “clearness;” figuratively “celebrity, renown, fame,” from clarare “make clear,” from clarus “clear” (see clear (adj.)). Modern form is early 15c., perhaps a reborrowing from Latin. Meaning “clearness” is from 1610s.
