0.2. The Kartvelian languages may be viewed as descendants of a common language that existed in the past, of which different transformations yielded historically attested cognate linguistic systems.

1 The theory of which this article presents the essential conclusions has been set forth in Th. V. Gamkrelidze and G. I. Machavariani, The system of sonants and ablaut in Kartvelian languages, Tbilisi, 1965 (in Georgian and Russian).
2 In the following formulas the symbol C stands for any consonant, V for any vowel;
