Dialects
The Hurrian of the Mitanni letter differs significantly from that used in the texts at Hattusha and other Hittite centres, as well as from earlier Hurrian texts from various locations. The non-Mitanni letter varieties, while not entirely homogeneous, are commonly subsumed under the designation Old Hurrian. Whereas in Mitanni the vowel pairs i/e and u/o are differentiated, in the Hattusha dialect they have merged into i and u respectively. There are also differences in morphology, some of which are mentioned in the course of the exposition below. Nonetheless, it is clear that these represent dialects of one language. Another Hurrian dialect is likely represented in several texts from Ugarit, but they are so poorly preserved that little can be said about them, save that spelling patterns used elsewhere to represent Hurrian phonemes are virtually ignored in them. There was also a Hurrian-Akkadian creole, called Nuzi, spoken in the Mitanni provincial capital of Arrapha.
