Etymology
It is Middle English sope, inherited from Old English sāpe (“soap, salve”),[2][3][4] from West Germanic *saipō,[5][2] source also of Dutch zeep and German Seife,[2][3] perhaps from PIE Proto-Indo-European *seyb- (“to pour out, drip”), also perhaps the source of Latin sebum (“tallow”).[3][4] Late Latin sapo, first mentioned by Pliny as a hair dye, is a Germanic loanword and gave French savon and Italian sapone.[3][2]
Earliest recorded meaning
A substance of oils or fats combined with alkali, used for washing: about 1000.[6][2] Etymonline says it was anciently a reddish hair dye used by Germanic warriors.[3]
Semantic evolution
The verb, to rub with soap, is from 1585.[2][4] Flattery is from 1853–54, compare soft soap,[3][6] and money, especially for bribery, is American slang from 1860.[6] No soap, a refusal or failure, is from 1926.[6] The soap opera, a radio or television serial, is American, from 1939, named after the soap manufacturers who sponsored early programmes,[2] and is shortened to soap.[7][8] The soapbox is recorded from 1660.[2]
