Proto-North Caucasian: *ṭHä̆lq̇_wV / *q̇_Hwä̆lṭV
Meaning: part of leg
Notes: Reconstructed for the PEC level. Except for the metathesis (a frequent phenomenon in roots of this structure), correspondences are regular.
It is very tempting to compare also Av. ṭiq̇:ʷá 'horseshoe; sole of foot', Chad. ṭuq̇:é-n 'horseshoe'. However, dialectal forms (Andal. uq̇:a) show that here ṭ- goes back to Proto-Avar *ƛ̣- (*ƛ̣iq̇:ʷa). The comparison is thus possible only if we assume a non-trivial assimilation in Proto-Avar: *ƛ̣iq̇:ʷa < *ṭilq̇:ʷa. The inclusion of the Av. form (paradigm B: ṭiq̇:ʷá-dul, ṭuq̇:-bí, Chad. ṭuq̇éni-l, ṭuq̇-bí/ṭuq̇ná-l) would allow to make the PEC reconstruction more precise: *ṭɦä̆lq̇_wā ( ~ -ǝ̄).
