Hurrian language
Within a few centuries of the fall of Washukanni to Assyria, Mitanni became fully Assyrianized and linguistically Aramaized, and use of the Hurrian language began to be discouraged throughout the Neo-Assyrian Empire. However, Urartean, a dialect closely related to Hurrian seems to have survived in the new state of Urartu, in the mountainous areas to the north in their Armenian Highlands.
