Notes: Reconstructed for the PEC level. Correspondences are basically regular with following comments: in PN there occurred a dissimilation in glottalisation (*ḳ- > *k- before the following ḳ); in PTs we should expect -ɔ̃- in the 1st syllable, but it was probably assimilated by the following vowel (nasalisation being replaced by pharyngealisation, cf. the Inkh. form?). All these processes are typical for EC reduplicated roots and roots with two stops.
EC > Osset. ḳax 'foot, leg' (see Abayev 1958, 619).
