1911 Encyclopædia Britannica/Sash

SASH. (1) A framework of wood in which glass is fixed for a window, particularly a framework for large panes of glass in two parts which open and shut by sliding up or down. The word is a corruption of the Fr. châssis, châsse, Lat. capsa, box, case, capere, to hold. The word is, therefore, a doublet of “case” and “cash” (qq.v.) (2) A long band of silk or other fine or ornamented material worn round the waist or over the shoulders as part of a woman’s or child’s dress, or as a sign or badge of office, or as part of an official costume or uniform. The word is an adaptation of the Arab. shāsh, muslin, especially used (of the soft muslin or silken bands used for wrapping round the head in the form of a turban). In its early uses in English it appears as a term used by oriental travellers and writers on the East as an equivalent for a Mahommedan.
