|Linguistic classification:||Northwest Caucasian|
The literary dialects of Abkhaz and Abaza are two ends of a dialect continuum. Grammatically, the two are very similar; however, the differences in phonology are substantial, and are the main reason many linguists prefer to classify them as distinct languages. Most linguists (see for instance Viacheslav Chirikba 2003) believe that Ubykh is the closest relative of the Abazgi dialect continuum.
