Comments: PTsKh *ʔoc̣ǝ-(no); PGB *ʔɔc̣ǝ-n(ɔ) (for Gunzib Bokaryov has recorded oc̣ǝn: the correct form is probably ɔc̣ǝn or ɔc̣c̣ǝn with emphatic gemination). Most languages have not preserved nasalisation of the first vowel (lost by dissimilation to the nasal suffix -nɔ); the Khvarsh. and Inkh. form, however, speak strongly in favour of nasalised *ɔ̃ in PTs.
