قورساق

The possibility of the latter being a derivation of *kūr�k or *kūr�gak ( “dry” ) was proposed already by Kashgari, who connected it with قُرُغْسٖیماقْ‎ ( kuruɣs�māq, “to dry” ) ( "This is why 'stomach' is called قُرُغْساقْ‎ ( kuruɣsāq ) , since it dries out for every hour that passes and a hunger for food arises in it. " ) . There is, however, a possibility that the Karakhanid form is metathesized under the influence of a folk etymology, which also found its way into Dīwān Lughāt al - Turk.
R�s�nen held that the word is derived from *kur ( “belt” ) * - sak ( as in bağırsaq ) .
Yet another view, that of Sevortjan, held that *kur in *kursak is synonymous with *kar, as in *kar�n ( “stomach” ) , this view is, however, not supported anymore.
