COMMENT: An Aand-Lezg. isogloss. Except for metathesis (rather a frequent feature), all correspondences are regular.
An interesting form is Arch. duχ:ur 'farmstead': this is probably an old loanword from Av.-And. with a later Arch. change r- > d- (duχ:ur < *riχ:ʷV-r), thus constituting an etymological doublet with Arch. χIor 'village'.
