Usage Celtic Mythology
Meaning & History
Probably from early Celtic meaning "light", ultimately from the Indo-European root *leuk "light, brightness". This was the name of a Celtic (Gaulish) god of commerce and craftsmanship, who was equated by the Romans with Mercury. He probably forms the basis for the characters and names of Lugh (Irish) and Lleu (Welsh).
