In Case You’re Interested
Comes from Old English zefferus, which comes from Latin zephyrus, which comes from Greek ζέθυρος, all of which mean and are pronounced the same. Historically used for the god of the west wind, Zephyrus, or for the west wind itself, by the early 1600’s it was being used (notably by Shakespeare) as a poetic word for any light breeze or wind. There is also a light fabric called zephyr, the sort of thing you might wear in one.
