From a Chuvash-type Turkic language before the times of the Hungarian conquest of the Carpathian Basin (at the turn of the 9th and 10th centuries), compare Cuman Kipchak (učuχ, “chaff”), Turkmen (uǰuq, “refuse grain”), and Tatar (očoq, “chaff”), ultimately from Proto-Turkic *uč- (“to fly”). For the development of the ending in Hungarian, compare apró, borsó.[1] Originally it referred to the part of grain left over after riddling, sifting, or sprinkling (hence “flying”).[2]
