lather

Etymology and origin of the English word lather

History Permalink

Pronunciation

  • IPA: /ˈlɑː.ðə/, /ˈlæð.ə/ (UK); /ˈlæð.ɚ/ (US)[1]

Etymology

The noun goes back to Old English lēaþor “washing soda, soap, foam”,[2][3][4][5][6] from Proto-Germanic *lauþrą,[3][4] related to Old Norse lauðr (“foam, washing soap”).[3][4][6] Watkins traces it to a Proto-Indo-European root *leue- “to wash”, the source of Latin lavo (“to wash”).[4][5] The verb comes from Old English lēþran “to cover with lather”.[2][3][4]

Earliest recorded meaning

As a verb, to cover with lather (about 950);[3][7] as a noun, a froth of soap and water (about 1000).[7][3]

Semantic evolution

The noun seems to be missing in Middle English and was probably formed again from the verb in the 16th century (1583).[3][4] From 1660 it meant the frothy sweat of a horse,[7][4] and from 1839 a state of agitation such as makes one sweat.[7][4] The verb, to produce a lather, is from 1608,[7][4] and to beat or thrash from 1797.[7]
