Word Origin & History

mast  (1)
"long pole on a ship to support the sail," O.E. mæst, from P.Gmc. *mastaz (cf. O.N. mastr, Du., Ger. mast), from PIE *mazdos "a pole, rod" (cf. L. malus "mast," O.Ir. matan "club," Ir. maide "a stick," O.C.S. mostu "bridge"). Masthead is from 1748 as "top of a ship's mast" (the place for the display of flags), hence, from 1838, "top of a newspaper." The single mast of an old ship was the boundary between quarters of officers and crew, hence before the mast in the title of Dana's book, etc.

mast  (2)
"fallen nuts; food for swine," O.E. mæst, from P.Gmc. *mastaz (cf. Du., Ger. mast "mast," O.E. verb mæsten "to fatten, feed"), perhaps from PIE *mazdo-/*maddo- "to be fat, to flow" (cf. Skt. meda "fat," Goth. mats "food," see meat).
