fustian Look up fustian at Dictionary.com
"thick cotton cloth," c.1200, from O.Fr. fustaigne, from M.L. fustaneum, probably from L. fustis "staff, stick of wood," probably a loan-translation of Gk. xylina lina "linens of wood" (i.e. "cotton"), but the M.L. word is also derived from Fostat, town near Cairo where this cloth was manufactured. Figurative sense of "pompous, inflated language" first recorded c.1590.
