Dialects
There is also a considerable difference between the spoken and written forms of the language. Spoken Kannada tends to vary from region to region. The written form is more or less consistent throughout Karnataka. The Ethnologue reports "about 20 dialects" of Kannada. Among them are Kundagannada (spoken exclusively in Kundapura), Nadavar-Kannada (spoken by Nadavaru), Havigannada (spoken mainly by Havyaka Brahmins), Are Bhashe (spoken by Gowda community mainly in the Sullia region of Dakshina Kannada), Soliga, Gulbarga Kannada, Dharawad Kannada etc. All of these dialects are influenced by their regional and cultural background.
Ethnologue also classifies a group of four languages related to Kannada, which are, besides Kannada proper, Badaga, Holiya and Urali.
