Wa-an, or the Wa language, was a language spoken by the Wanese, inhabitants of Wa in Kara-Tur. Wa-an descended from the ancient Han language, as did Koryo and Kozakuran, and possibly others. Wa-an and Kozakuran were closely related; some considered them only different dialects of the same language. There was perhaps 65% comprehension between the two. Wa-an was abundant with polite expressional and flowery terminology. Etiquette rather than grammar regulated the proper usage of many phrases.
