similarly...
vehicular cycling = following the vehicular rules of the road
vehicular rules of the road = how a vehicular cycling cyclist rides
Those are both circular. These are not:
entomology = the study of insects
entomologist = person who engages in entomology
vehicular rules of the road = rules of the road that pertain to the operation of vehicles.
vehicular cycling = cycling per the vehicular rules of the road
Do you see and appreciate the difference?
