borage: borage: [13] The plant-name borage comes via Old French bourrache from Latin borrāgo. Various words have been advanced as an ultimate source, including late Latin burra ‘shaggy cloth’, on account of its hairy leaves, but in view of the fact that the Arabs used the plant medicinally to induce sweating, the likeliest contender is Arabic abū ‘āraq, literally ‘father of sweat’.
behemoth (n.): late 14c., huge biblical beast (Job xl:15), from Latin behemoth, from Hebrew b'hemoth, usually taken as plural of intensity of b'hemah "beast." But the Hebrew word is perhaps a folk etymology of Egyptian pehemau, literally "water-ox," the name for the hippopotamus.
Long before Jumbo was dreamed of, a hippo was exhibited by George K. Bailey, who invented the tank on wheels now used so generally in the circuses. The beast was advertised as "the blood sweating Behemoth of Holy Writ," and he made several men rich. [Isaac F. Marcosson, "Sawdust and Gold Dust," in "The Bookman," June 1910]
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.
stove (n.): mid-15c., "heated room, bath-room," from Middle Low German or Middle Dutch stove, both meaning "heated room," which was the original sense in English; a general West Germanic word (Old English stofa "bath-room," Old High German stuba, German Stube "sitting room").

sudatorium (n.): "room in a bath for sweating," 1756, from Latin sudatus, past participle of sudare "to sweat," from sudor "sweat" (see sweat (v.)) + -orium (see -ory).
