The consideration of the languages of the Kartvelian branch, as agglutinating and those pertaining to satellite typology, as morphologically rich languages (MRL) should be based on the following criteria: number of grammatically marked categories; number of free and bound morphemes within a word-form; a number of word-form for each lexemes; fusional morphonology.Kartvelian substantives are inflected only for two grammatical categories, whereas the Kartvelian verb may be inflected for 11-13 categories being classified as those of conjugational and derivational. In the Kartvelian languages, nominal and verbal structures are made of bound morphemes. A general number of morphemic markers in morphological structures of the Kartvelian substantives and verbs are more or less varied; simultaneous representations of combinations are based on morphological rules. Initial patterns of a verbal paradigm vary with respect to the categories of version, voice, causation, to a kind of subject-object order; these also facilitate an occurrence of a great number of inflected verbs. In the verbal structure of the unwritten Kartvelian languages, phonology hardly counts with morphology; therefore, fusional morphemes occur as a result of phonetic transformations at morpheme boundaries. In verbal inflections, numbers of homoforms vary with respect to a language; abundant inflection is a condition for considering the Kartvelian languages as morphologically rich ones.
