Etymology

edit

From Middle English Milky Wey, a calque of Latin Via Lactea (literally “milky road”), a calque of Ancient Greek γαλαξίας (galaxías), referring to its appearance as a pale band of stars across the sky. Compare also Old English Īringes weġ (“Milky Way”), Old Norse Mjólkrhringr (“Milky Way”, literally “milk-ring, milk-circle”). The reference to the galaxy is an extension of the second sense.
