Why is the ninth month called September?
"thick cotton cloth," c.1200, from Old French fustaigne, from Medieval Latin fustaneum, probably from Latin fustis "staff, stick of wood," probably a loan-translation of Greek xylina lina "linens of wood" (i.e. "cotton"), but the Medieval Latin word also is sometimes said to be from Fostat, town near Cairo where this cloth was manufactured. [Klein finds this derivation untenable.] Figurative sense of "pompous, inflated language" recorded by 1590s.
fabric originally made by weaving two sets of cotton wefts, or fillings, on a linen warp, popular during the European Middle Ages. The word has come to denote a class of heavy cotton fabrics, some of which have pile surfaces, including moleskin, velveteen, and corduroy.
