Attested since the 1610s, from the earlier form trouzes (attested since the 1580s), extended from trouse (1570s), with plural ending typical of things in pairs, from Middle Irish triubus (“close-fitting shorts”), from Old Irish tribus, of uncertain origin. The unexplained intrusive second -r- is perhaps due to the influence of drawers. Doublet of trews (“trousers”). Old Irish tribus is probably a borrowing of Anglo-Norman tribuz, trebuz, from Old French trebus, from Old Occitan trebucs, trabucs, from Late Latin trabrugi, tribuces, tubruci (“leg-coverings”), from an early Germanic language, perhaps Gothic *𐌸𐌹𐌿𐌷𐌱𐍂𐍉𐌺𐍃 (*þiuhbrōks) or Old High German diohbruoh (“loincloth, trousers”), ultimately from Proto-Germanic *þeuhabrōks (“loincloth, trousers”), a compound of Proto-Germanic *þeuhą (“thigh”) + *brōks (“leggings, trousers”), equivalent to thigh + breeches. Compare obsolete Modern German Diechbruch (“short legwear, knee breeches, loincloth”).
