Proto-West-Caucasian: *(pǝ-)ʒ́ʷǝ
Meaning: 1 dusk 2 evening
Abaza: ala-bǝǯ 1
Adyghe: pč́ǝ-ħa 2
Kabardian: pśǝ-ħa-śħa 2
Ubykh: zʷa-psǝ́-ǯ́
Comments: The basic meaning of the root *(Pǝ-)ʒ́ʷǝ is "dusk, evening (or morning) dawn". In Abkh. it was lost, and in Abaz. stayed only within a compound with (a)la- 'light' (same as in la-šara 'light', historically = "eye").
In PAK the root *pćV ( < *P-ʒ́ʷǝ with devoicing) is used in compounds *pćǝ-ħa 'evening' (listed above) and *pća-dǝ- 'morning, tomorrow' (Kab. pśa-dej 'tomorrow', pśa-dǝ-ǯǝz 'morning', Ad. pč́a-dǝž́ 'morning'). Finally, in Ub. the root -ǯ́ is also used only in compounds: zʷapsǝ́-ǯ́ 'evening' (with zʷapsǝ́ id.) and sʷǝ-ǯ́ '(morning) dawn' (with sʷǝ id.).
