A language is a language but anybody can speak it and ever race, and all the sub-races underneath had a main language of political and religious prestige. This isn't mean to be exhaustive, I'm not an expert at every race:
Asian Zevists: Mandarin Chinese for daily use, Classical and Zhou Chinese for religious uses (China, Japan, Korea, Singapore and Vietnam), Old Turkic (Central Asia and Mongolia), Malay (Indonesia, Malaysia, Philippines, Brunei, East Timor)
White Zevists: Russian for bussiness & Church Slavonic for religious (Russia, Ukraine, Yugoslavia, Bulgaria and etc.), German and Norse (for Central/Northern Europe), Latin (for Romance speakers), Aramaic (Middle Eastern)
Black Zevists: Egyptian (Nile River and Libya)....that's all I can say because Black civilization isn't in my forte
