Comments:ССЕ 198. The Pump. form oksɨ (Срсл., Кл.) is in reality Yug. The key to the etymology is probably the Kottish paradigm: atči 'tree', plur. ak / ax, āx. The plural form here undoubtedly reflects PY *xaʔq 'tree, wood' (q.v.). One can therefore suppose that PY *xɔksi is a transformation of the original compound *xaʔq-sV or *xaʔq-xusa, lit. "one tree" (a compound analogous to *de-s 'eye' etc.) - cf. a similar later formation in Arin kus-ošče. The transformation of vocalism, however, is still to be explained.
