Proto-North Caucasian: *HVq̇V
Meaning: down, below
Notes: Reconstructed for the PEC level. Archi q̇a-t:u is an exact parallel for Av. ʕo-do-. The root is not very widely spread, and the first syllable is often reduced (because of suffixes and its adverbial character), so the vocalism is hard to reconstruct.
