Комментарии: PTsKh *ʔɨs / *ʔɨseju; PGB *ʔɨs / *ʔɨsi(j). In all modern Tsezian languages except Bezhta the stem denotes both 'brother' and 'sister' (the difference being only in agreement: 'brother' belongs to the 1st class, 'sister' - to the second). It is possible, however, that Bezht. preserves the old PTs opposition between *ʔɨs: 'brother' and *ʔɨs:Vju 'sister' (confused in all other languages).
The oblique stem of the word is well reconstructable for PTs as *ʔɨs:-ṭi-: Inkh. ɨsṭi-, Bezht. isṭi-, Gunz. ɨsṭi-.
