Opinions regarding origin and functions of Megrelian-Chan suffixes
k- and r- differ in special literature:
The Chan r- and Megrelian k- suffixes could be connected to
each other on the basis of morphological function (Arn. Chikobava,
1936, p. 112, 115, 135).
The Megrelian k- and Chan r- suffixes have the same origin.
Their function, similar to the auxiliary verbs is Abkhazian and Kabardinian,
included expression of static nature, state and existence. k- and r-
suffixes represent a remainder of ore(n) "is" auxiliary verb (koren >
with ko particle added in Megrelian and without this particle in Chan),
which, similar to the Georgian verb, must be added to a verb in perfect
in Megrelian. From here it must be shifted to Present – first in the static
passive, and then to certain middle-voice verbs (K. Lomtatidze, 1946, p. 134).
Megrelain k- must be derived from the affirmative ko- particle
following the loss of a vowel, resulting in enclitic combination with a
verb form: ko-v-ĉarun-k< ko-v-ĉarun-ko... (T. Putkaradze).
The formation of the imperfect screeve is based on the same rule
in Kartvelian sub-systems: it uses the present stem as a basis to which a
screeve extention and marker are added. Suffix -d is common for all
Kartvelian dialects. There is some specificity regarding the screeve
markers (especially in Svan dialects).
In Literary Georgian suffix -i is added as a screeve marker to both
transitive and intransitive verbs in imperfect screeve in the 1st and 2nd
person (the screeve marker is omitted in the 3rd person). -d occurs as a
screeve extention in transitive verbs: v-ċer-d-i "I was writing", ċer-d-i
"you were writing", ċer-d-a "s/he was writing"...
The verbs with -av, -am thematic markers similarly conjugate in
modern Georgian literary language: v-ķl-av-d-i "I was killing", ķl-av-d-i
"you were killing", ķl-av-d-a "s/he was killing"... cf.: Old Georgian: v-ķlev-d(i),
ķl-ev-d(i), ķl-v-i-d-a...
In dialects the verbs with -av, -am thematic markers conjugate
differently:
a) -av, -am remains unaltered in Kartlian, Kakhetian, Her, Mokhevian,
Mtiul-Gudamakarian, Pshavian, Imeretian dialects: ķl-av-s "s/he
