Recent revert for root
From User talk:Rua
Ankitdimania (talk)
I don't understand the PIE pages on this point either. The Germanic form can't reflect *gʷreh₂- because that would result in *krō- or in zero grade *kur-. If there are sources that state that *kwernuz really is from this root, then they also need to explain how that is possible. I suggest bringing the matter up in WT:ES so that others can also contribute.
