About This Root

From Old English lēoht (bright) and līht (not heavy), two originally distinct words that merged. The brightness sense produces lighthouse, daylight, sunlight, moonlight, spotlight, flashlight. The 'not heavy' sense gives lightly, lighten, lighthearted. This dual meaning is a distinctive feature of the English word.
