This paper seeks to throw new light on the origin of the Kiev Leaflets by comparing the toponyms in Pannonia and the toponyms in the northern Tisa region. In the northern Tisa region, the Uh-Sotak dialect has been spoken. This dialect seems to be very archaic and able to preserve old linguistic features, including accent. The accent of the Sotak dialect of Koromľa, recorded by O. Broch in 1899, is very similar, maybe identical to one in the Kiev Leaflets. Moreover, in the Uh-Sotak dialect we can find all the important phonetic and morphological features of the Kiev Leaflets, such as *tj/kt > c, *dj > (d)z, *sk/*stj > šč, *dl > l, epenthetic l, roT-, dobrajego > dobraego > dobraago > dobrago, as well as *jь- > *iand then prīmi/primi, I sg. m. -ъmь/-emь, D sg. teb-, G pl. f. -ach, maybe *vьch- > vьs-, and no G sg., A pl. f. of ja-stems -ě. The toponyms of the northern Tisa region seem to be in accordance with the dialect of the Kiev Leaflets, too.
