Comments: PAT *ṭǝ; PAK *t:ǝ-ʁʷrǝʁʷǝ́. Despite the irregularity (ṭ : t:) the comparison of PAT and PAK is quite probable (see Шагиров 1, 154), especially because in Abkh there also exists a compound a-ṭǝ́-ʕʷarʕʷar 'eagle-owl' ( = PAK *t:ǝ-ʁʷrǝʁʷǝ́); etymology of the second part see under *ʁʷVrǝʁʷǝ.
Ub. tǝʁʷrǝʁʷ 'owl', because of its t-, is probably not genuinely related, but borrowed from Adygh. However, despite Abdokov (1983, 122), Ub. dǝma 'hen' is hardly related.
