COMMENT: Reconstructed for the PEC level. The verb has class prefixes only in Lak. and Darg. Several languages have an interesting opposition 'to eat (objectless)' : 'to eat (smth.)': Av. Chad. kuná-ji : kʷén-ži; Darg. Chir. =erkʷVn- / =uk- : =uk- / =uk-; Arch. kúm-mus (dur. kúkin, term. kúnni) : kum-mús (dur. kʷan, term. kunné).
