köken: Uncertain, presumably a loan from an unidentified Mediterranean substrate according to Treccani. Note, however, similarities to grano (“grain”) and mola (“grindstone, millstone”), suggesting that the word may be a dialectal blend of the two.
köken: From Middle Dutch brâke (“fallow land”), from Proto-West Germanic *brāku. Cognate with German Brache (whence also the adjective brach), Old English brǣc (“plowed land”). Related with breken (“to break”), so called because the field is plowed (“broken”) and then left in this state.
köken: From Proto-Celtic *kanxstikā, from Proto-Indo-European *ḱonḱ-, *ḱonk- (“horse”); compare Dutch hengst (“stallion”), Lithuanian šankùs (“nimble”), Persian خنگ (xeng, “gray horse”). Matasović also compares this word to Proto-Celtic *kengeti (“to step”).
