Origins

Meanings 1–21, 23

Old English took lagu ("law") from Old Norse lǫg ("law"), whose literal sense was "things laid down or firmly established", and it became Middle English lawe. The Norse word goes back to Proto-Germanic *lagą, meaning "that which is laid down", and a Proto-Indo-European root meaning "to lie". Though it looks similar, it is not usually thought to share an origin with legal or French loi, both of which come from Latin lēx.
