COMMENT: Reconstructed for the PEC level. We have reconstructed the structure *Hrĕmk_wɨ̆, taking into account the relic nasalisation in Gunz.; if it is secondary, a reconstruction *rHĕk_wɨ̆ is also possible.
An obvious EC loan is Osset. ryg 'dust' (see Abayev 1973, 444; the suggested Indo-Iranian etymology of the Osset. word is absolutely unsecure).
