Tofa is most closely related to the Tuvan language[4] and forms a dialect continuum with it. Tuha, and Tsengel Tuvan may be dialects of either Tuvan or Tofa. Tofa shares a number of features with these languages, including the preservation of *d as /d/ (as in hodan "hare" - compare Uzbek quyon) and the development of low tones on historically short vowels (as in *et > èt "meat, flesh").
