Comments: PAK *wǝgǝ- (also a noun *wǝgǝ́ > Ad. wǝǯ́ǝ, Kab. wǝǯ 'round dance with singing'); Ub. sǝ-wǝ́ǵǝ-n (qualified as an Adygh loanword in Vogt 1963, but possibly genuine). *wǝ- is a common WC morpheme with the meaning 'to do, to make (smth.)'; PAT *aga (Abaz. laga is perhaps influenced by lǝg 'slave'?). The same root (reduplicated, or at least constituting the first part of a compound) can be found in PAK *gagʷǝ- 'to play' (Ad. ǯ́agʷǝ-n, Kab. ǯagʷǝ-n), *gágʷǝ 'play, feast, wedding' (Ad. ǯ́agʷ, Kab. ǯagʷ).
The semantic correlation "to dance, play" - "to be silly" recurs in the same root in EC languages as well, thus the relationship between AT and other WC forms seems secure enough.
