Comments: PAT *ɣ́a / *ɣ́ǝ (the latter form is used in compounds, cf. Abkh. a-tǝ́-ʁ́, Abaz. tǝ-ʁ́ 'ram', Abkh., Abaz. abǝ-ʁ́ 'he-goat'; also in the meaning "seed, egg", e.g. Abkh. a-ḳʷṭá-ʁ́, Abaz. ḳʷṭaʁ́ '(hen's) egg'). PAK *ɣa.
Ub. has also a word ɣa 'testiculus', but it is obviously an AK loanword. The genuine reflex of PWC *Ł́A is Ub. -źa in tʷá-źa 'he-goat' ( = Abkh. abǝʁ́), ṭǝ-źá 'ram' ( = Abkh. a-tǝ́ʁ́) and ba-źá 'penis'.
