Прасинокавказский: *nHǟ́ƛ̣wV̆
Значение: dark, blue
Комментарии и ссылки: The semantic connection of 'blue' and 'iron' is found in PNC *nHǟƛ̣_wV̆ 'blue; (blue metal) > iron' and Bsq *urdi-n 'blue, gray', *burdina 'iron'. It is uncertain whether this association existed already in the ancestor of Bsq and NC, or developed independently. If original, the word may have referred to rare, and expensive, meteoric iron.
