Notes: Despite some assimilations (quite usual for stems with two stops), the correspondences are quite regular and the PNC reconstruction is quite probable. Not quite clear, though, is -r- in the PA form: *borto may go back to *bot(V)-ro with an original suffixation. It is interesting to note initial ħe- in the Av. form, corresponding to Arch. pharyngealization and speaking in favour of the initial cluster *Hp- in PNC.
Note also Chech. bedar (Cheb. badir) "clothes" which is probably a loan from Western Daghestan languages (loss of *-d- would be regularly expected).
