Different kinds of sound correspondence instances could be explained
by different reasons.
"a process which is not regular to any certain dialects manifests a
common Kartvelian potential… certain facts, occurred in a certain dialect
might historically characterize it or later define its phonetic patterns"
(B. Jorbenadze, 1998, p. 150).
"Something considered as a sound correspondence of current
Kartvelian languages has been historically characteristic to the dialects
of these languages" (B. Jorbenadze, 1995, p. 56).
"Related languages and, at the same time, their own dialects consist
numerous phenomena that have common basis (B. Jorbenadze)" i.e.
there is no substantial difference between a proto language and a modern
variant. We must naturally suppose parallel occurrence of the phonetic
variants of word forms in common Kartvelian similarly to the current
situation (T. Putkaradze, 1996, pp.23-24).
We believe, it is essential to define reasons why the widely
known sound correspondences have been developed. It is an interesting
fact that in the vocabulary by G. Eliava the identical words with an initial
letter ĉ constitute 40%, correspondences - 29%, and 31% is to be
studied. Researchers omit numerous identical words from the vocabularies.
Thus, reconstruction of double ĉ (or double ċ, ĵ, c) consonants in
common Kartvelian, as well as explaining identical forms by means of
borrowings, seems unreasonable. Presumably, regular sound correspondences
originate from the phonetic variants extant in common Kartvelian
itself. This is deduced from similar facts in the Kartvelian subsystems.
Thus, it seems more logical to search for reasons of so-called
Kartvelian correspondences in phonetic cluster and other factors rather
than in "articulation shift backward".
Tendencies of phonetic alterations in the Kartvelian sub-systems
are generally common; for instance, on vowel reduction in the Kartvelian
sub-systems see: I. Kipshidze, 1914; M. Tsikolia, 1950; S. Zhghenti,
1953; M. Tsikolia, 1954; T. Uturgaidze,1976; A. Shanidze, 1981; M.
Nikolaishvili, 1984; B. Jorbenadze, 1998, etc. On transformation of vowel
complexes see: I. Kipshidze, 1914; Arn. Chikobava, 1936; A.
