- musk (n.)
- late 14c., from Old French musc (13c.) and directly from Late Latin muscus, from Late Greek moskhos, from Persian mushk, from Sanskrit muska-s "testicle," from mus "mouse" (so called, presumably, for resemblance; see muscle). The deer gland was thought to resemble a scrotum. German has moschos, from a Medieval Latin form of the Late Greek word. Spanish has almizcle, from Arabic al misk "the musk," from Persian. Applied to various plants and animals of similar smell (e.g. musk-ox, 1744).
