roadway

The word 'roadway' is a tautological compound formed from two Old English nouns, both meaning a path or course for travel. 'Road' originally referred specifically to the act of riding or a journey on horseback, its meaning broadening over time to denote any path for travel. 'Way' is a more general term for a path, road, or course. The compound 'roadway' emerged to specify the physical, defined part of the road intended for vehicular passage, distinguishing it from the roadside or the broader concept of a route. Thus, the word's logic is one of semantic reinforcement, combining two ancient terms for a path to create a precise term for a modern thoroughfare.
