well the Aztecs from tenochtitlan called themselves Mexica Tenochca so a sinification might be something like Meixike Tenosha, or perhaps just Tenosha or perhaps the P'urhepecha (the Tarascans, a people who lived on the western half of Mexico and the other empire to the Aztecs) or some other western peoples name for the Aztecs. No idea what those would be, as many of those languages are dead or highly obscure.So the sinified name of the Empire would be "Mei Xi 'Ke" then....![]()
