Consonant clusters

In a syllable onset, a stop or affricate may be followed by a liquid (*l, *r). Any consonant except a labial may be followed by *w (possibly, these were labialized consonants rather than clusters). A stop/affricate+liquid cluster may also be followed by *w.

In a syllable coda, no clusters may appear.

Vowels

	Front	Central	Back
High	*i		*u
Mid	*e		*o
Low		*a

The position of the vowel *o is marginal. It occurs only in very few words, though some of these are quite common. None of these words appears to have a Kartvelian cognate; most of them are similar to some Eteonoric words. Hence, it is believed that these words were borrowed from a (Mesolithic?) language related to Eteonoric, or both families borrowed them from an unknown third source.
