What has this question got to do with Verner if the medial consonant is
PIE *d? VL applies only to PGmc. voiceless fricatives that developed
from PIE *p, *t, *k(^), *kW and *s via Grimm's Law.
However, if your new question is independent of my previous reply, the
o-grade is the same as in other thematic deverbals of the well-known
type *R(o)-ó-, denoting agents or verbal adjectives with active
meanings, like *dHrogH-ó-s 'running --> wheel' (Gk. trokHós, OIr.
droch). You know the <tomós> type, don't you?
