the word 'tollway' is a modern english compound, transparently combining two ancient germanic elements. 'toll' descends from proto-germanic tullō, referring to a charge or tax, a concept essential to trade and passage. 'way' traces back to proto-germanic wegaz, denoting a path or road, from the pie root weǵh- meaning to go or transport. the compound's logic is direct and descriptive: a 'tollway' is literally a 'way' or road on which a 'toll' or fee is levied for passage, a concept that evolved from medieval toll roads to modern controlled-access highways.
