From Late Latin 'viaticum' (travel provisions), from 'via' (road) — provisions became the journey itself.
A long journey, especially by sea or through space; to make such a journey.
From Old French 'veiage' / 'voiage' (a journey, a pilgrimage), from Late Latin 'viāticum' (provisions for a journey, traveling money), from Latin 'via' (road, way, path), from PIE *weǵh- (to go, to transport). The same Latin root 'via' produced 'deviate,' 'trivial' (from 'trivium,' a place where three roads meet), 'convey,' 'envoy,' 'invoice,' and 'obvious' (standing in the way). The word's original sense of 'provisions for the road' narrowed to 'the road itself' and
The word 'trivial' is a distant relative of 'voyage' — both trace to Latin 'via' (road). 'Trivial' comes from 'trivium' (a place where three roads meet, a crossroads), which was associated with commonplace, everyday conversation — the kind of talk you might hear at a busy intersection. Commonplace information is 'trivial' because it is the kind of thing found at every crossroads.
