That hat/hood word was assigned to NWBlock by Kuhn since it couldn't
fit into a purely Germanic pedigree. Perhaps other supposed
NWBlock words can be located here? Eg
k'opp "can, (wooden) mug"
c'upp "top"
where the cognates of 'cup' and 'top' in Proto-Germanic can't be
directly from PIE because the root constraint outlawing roots of type
**ged-.
