mantle: [13] Mantle comes via Old French mantel from Latin mantellum ‘cloak’, a word of uncertain (possibly Celtic) origin. Related forms to find their way into English from other languages include mantilla [18] (a Spanish diminutive of manta ‘cape’, which came from Latin mantus, a shortened form of mantellum) and mantua, a term used in the 17th and 18th centuries for a woman’s loose gown, which arose from the association of modern French manteau with the name of the Italian city of Mantua, once famous for its silks. And the mantel [15] of mantelpiece is a variant spelling of mantle. => mantel[mantle etymology, mantle origin, 英语词源]
