The word 'voyage' charts a course from the concrete to the conceptual. Its ultimate origin is the Latin noun 'via', meaning 'road' or 'way', a term itself derived from the Proto-Indo-European root weǵh- meaning 'to go, transport in a vehicle'. This root passed into Old French as 'voiage', signifying a journey or the supplies for one. The suffix '-age', also of Latin origin via French, was attached to form a noun denoting the action or instance of traveling. Thus, the literal construction 'voyage' encapsulates the 'process or act of journeying', a meaning that has sailed from terrestrial roads to the high seas and beyond, while retaining its core sense of a significant, often lengthy, passage.
