lather: [OE] Indo-European *lou- denoted ‘wash’ (from it English gets laundry, lavatory, lotion, etc). Addition of the suffix *-tro- produced *loutrom, which passed via Germanic *lauthram into English as lather. In Old English this is only recorded as meaning ‘washing soda’, and the modern sense ‘soap bubbles’ does not emerge until the late 16th century. => ablution, laundry, lavatory, lotion
lather (n.)
Old English lauþr "foam, washing soda," from Proto-Germanic *lauthran (cognates: Old Norse lauðr "washing soap, foam"), from PIE *loutro- (cognates: Gaulish lautron, Old Irish loathar "bathing tub," Greek louein "to bathe," Latin lavere "to wash"), which is from root *leu(e)- "to wash" + instrumentative suffix *-tro-. The modern noun might be a 16c. redevelopment from the verb. Meaning "violent perspiration" (especially of horses) is from 1650s. Meaning "state of agitation" (such as induces sweating) is from 1839.
lather (v.)
Old English laþran, from Proto-Germanic *lauthrjan (source also of Old Norse leyðra "to clean, wash;" see lather (n.)). Related: Lathered; lathering.
