COMMENT: Correspondences are regular. This etymology for PAK *ʡʷǝ 'mouth' is phonetically preferable to Trubetzkoy's comparison with Av. abize 'say' (see Trubetzkoy 1930) or Balkarov's comparison with Av. ḳal 'mouth' (Balkarov 1964, 101). Abdokov (1983, 76) correctly compares the WC form with Gin. haqu (misspelled as haq̇u), but adds also Av. ḳal and other unrelated EC forms.
