Proto-West-Caucasian: *(Pǝ)č̣́V
Meaning: to cut, to incise
Adyghe: wǝ-ṗč̣́a-ta-n
Kabardian: wǝ-ṗṣ́a-ta-n
Ubykh: q́ǝ-č̣́-
Comments: PAK *wǝ-ṗč̣́a-ta-; there are also other compounds like *pǝ-wǝ-ṗč̣́ǝ- (Ad. pǝwǝṗč̣́ǝ-n, Kab. pǝwǝṗṣ́ǝ-n) 'to cut off'. Ub. a-s-q̇ǝ-č̣́ǝ́-n (q̇ǝ- < q̇a-, preverb meaning 'hand'). Despite Shagirov 2, 53 PAK *ṗč̣́a-/ *ṗč̣́ǝ- 'to cut, incise' should be kept apart from the homonymous *ṗč̣́a- 'to weed', which has its own etymology (q.v.). We should note that the semantic development 'to cut' > 'to weed', proposed by Shagirov, is highly unlikely (the basic idea of weeding is doing it by hand, not by knife or any other instrument).
