Proto-West-Caucasian: *ṗƛ̣a
Meaning: 1 leaf 2 foliage
Adyghe: ṗč̣́ā-ś 2
Kabardian: ṗṣ́ā-śa 2
Ubykh: ṗć̣a-pá 1
Comments: PAK *ṗč̣á-śa (the second component is not quite clear; without it cf. probably Kab. ṗṣ́i-j 'plane seeds' = "belonging to leaves", see Shagirov 2, 53; despite Abdokov 1983, 107 it is hardly a separate WC root). In Ub. cf. also ṗć̣á-wa 'leaf', ṗć̣ā́-d(ǝ)ʁa 'paper'. The correspondence PAK *č̣́: Ub. ć̣ points unambiguously to PWC *ƛ̣.
