Comment: In the adverbial use the root *ƛ̣:i- is preserved only in Archi and Budukh (Arch. ƛ̣:i-r, Bud. ko-rǝ with a not quite clear vowel reflex). All languages reflect the stem in the function of the locative suffix (in Udi - only within the adverb o-q:a 'below', formed from a pronominal stem). Most languages also reflect the same morpheme as a preverb (meaning 'below'): Lezg. ḳ(ʷ)-, Tab. k:-, Ag. k:-, Rut. g-, Tsakh. g-, Kryz. k-.
See Alekseyev 1985, 55, 119 (Alekseyev lists also the Bud. preverb č-, which is probably different in origin: cf. Bud. ače, Kryz. äčä 'below').
