Usage notes

A separate Late Latin muscus, “musk”, is borrowed from Ancient Greek μόσχος (móskhos), a word the TLL calls of Asian origin; it is found first in Jerome.[5][4][2] Medieval Latin also used it of muscatel wine.[6] English musk came partly from it, and muscat from a Vulgar Latin derivative.[7]
