A Fall into the Pit

This paper argues that Tocharian B koṣko, koṣkīye does not mean ‘hut’, as was taken for granted, but ‘pit, hole’; and that it is not an inherited Indo-European word, but an Iranian loanword in Tocharian B. Although the possibility of a borrowing from an unknown Middle Iranian language cannot be excluded, an unattested (Pre-)Bactrian form *kōškā is demonstrated to be the most likely source of this loanword.
