intermountain

The word is a modern English compound formed by directly combining a Latin prefix with an English noun. The prefix "inter-", from the Latin preposition "inter", has been a productive element in English since the Middle English period, borrowed via Old French. It retains its core spatial meaning of "between". The root "mountain" entered English from Old French montaigne, which itself descended from the Latin adjective montanus, meaning "of a mountain", derived from mons (mountain). The compound "intermountain" follows a transparent and logical pattern, literally describing something situated in the space separating mountain ranges. This term is particularly prevalent in the geographical descriptions of regions like the western United States.
