Праенисейский: *ʔapVj (~x-)
Значение: bellows
Кетский: āj (South.), North. āji3; plur. ājeŋ1
Югский: āfej1 / afe:j3, pl. āfejeŋ1
Коттский: afu 'forging', afu-het 'smith', afu-ākŋ 'to forge'
Примечания: ССЕ 182. Medial -f- in Kottish is not quite clear (-p- would be expected); a special development in front of -u- cannot be excluded. Werner (1, 94) treats the word as a compound of *ʔapV 'hotness' + *ʔāχ- 'sack' (q.v.); this may be applicable (as a folk etymology) to the Ket and Yug forms, but cannot explain the Kottish form (something like *afak or *apak would be expected).
