In PEC we must assume an assimilation (frequent in roots containing two stops) *kŏrdV > *gŏrdV. Otherwise correspondences are quite regular and the reconstruction seems reliable. Similar forms are observed in other Caucasian and geographically close languages: cf. Kartv. *kwrdeml- 'anvil', Az. ǵirdin 'log'. Klimov (1972, 352) must be right in supposing a Kartvelian source for some EC forms like Bacb. grdem 'anvil', Lezg. girdim 'log, block' (Klimov also lists Tsakh. ǵirdǝm 'log', Tab. gerdem, Ud. gürdüm 'big stone, boulder' - forms which we were unable to check; we can add to the list Bezht. gerden 'big stone; log', Khosh. gerem 'log', Inkh. geren 'hammer', finally, Av. geren 'small log, block'). However, the ultimate source of the Kartvelian forms is probably PNC *kŏrdV (with a productive suffix *kŏrdV-mV).
