Word Origin & History
soap
O.E. sape "soap" (originally a reddish hair dye used by Gmc. warriors to give a frightening appearance), from W.Gmc. *saipo- "dripping thing, resin" (cf. M.L.G. sepe, W.Fris. sjippe, Du. zeep, O.H.G. seiffa, Ger. seife "soap," O.H.G. seifar "foam," O.E. sipian "to drip"), from PIE base *seib- "to pour out, drip, trickle" (cf. L. sebum "tallow, suet, grease"). Romans and Greeks used oil to clean skin; the Romance language words for "soap" (cf. It. sapone, Fr. savon, Sp. jabon) are from L.L. sapo (first mentioned in Pliny), which is a Gmc. loan-word, as is Finnish saippio. The meaning "flattery" is recorded from 1853. The verb is first attested 1585. Soapstone (1681) is occasionally used for cleaning.
