means A long journey, especially one made by sea or through space, from one place to another.

from From Old French 'voiage' (a travel, journey, expedition), itself descended from Latin 'viaticum' — literally 'provisions for a journey,' from 'via,' meaning 'road' or 'way.' So buried in the word is the idea of packing for the road, of supplies laid in against distance. The same Latin 'via' paves the way for 'viaduct,' 'trivial,' and 'obvious.'
