Why was "tantrum" trending last week?
"feminine finery, sheer silk fabric," 1765, from French chiffon (17c.), diminutive of chiffe "a rag, piece of cloth" (17c.), of unknown origin, perhaps a variant of English chip (n.1) or one of its Germanic cousins. Klein suggests Arabic. Extension to pastry is attested by 1929.
in textiles, lightweight, sheer fabric of plain weave, usually of silk or one of the synthetic fibres. Although delicate in appearance, it is a relatively strong, balanced fabric and can be dyed or printed for use in dresses, millinery, scarves, and lampshades. The word chiffon is also used as a modifier to mean a lightweight or softly draping condition-e.g., chiffon velvet and chiffon taffeta.
