The word 'vogue' entered English in the late 16th century from the Middle French word 'vogue', meaning 'course, success, or fashion'. The French term derived from the Italian 'voga', which signified 'a rowing' or 'a course', and ultimately from the verb 'vogare', 'to row, sail, or move swiftly'. This nautical origin, linked to the idea of being borne along by the current, provides the core logic for its modern meaning. The semantic evolution moved from the literal sense of being carried forward on water to the figurative sense of being carried forward by popular opinion or trend. Thus, what is in vogue is what is currently 'sailing' or 'moving' successfully through the cultural landscape.

The entire word is a single, unsegmentable morpheme borrowed from French. Its functional role is as a noun.
