Kaisen or Kaiseni (žig wezanax [ʑug wɛzanɑx]) is a Milevic language spoken natively by about 23.7 million speakers, primarily in the Kaisen. It is related to other Milevic languages such as Farmoshi, Czisil and Dekkuvi, although as a member of the North Milevic branch it is most closely related to X. Since the early 1800s, Kaiseni has been regulated by the Terminian Institute for the Languages of the East, which introduced a uniform standard of spelling and pronunciation.
