Irish

From Middle Irish triubus, probably a borrowing from Old French trebus (“sort of foot covering”), from Late Latin tubrucus, tribuces (“thigh breeches”) (attested by Isidore), ultimately from Proto-Indo-European *bʰreg- (“to split, break”), possibly via Germanic (Old High German theobroch (“gaiters”), Gothic *𐌸𐌹𐌿𐌷𐌱𐍂𐍉𐌺𐍃 (*þiuhbrōks)).^[1]
