mountainside
UK: ˈmaʊn.tɪn.saɪd | US: ˈmaʊn.tən.saɪd
n. the sloping surface or area of a mountain; the side or flank of a mountain.
The word "mountainside" is a straightforward compound formed by combining "mountain" (from Old French montaigne, ultimately derived from Latin mons/montis meaning "mountain") and "side" (from Old English sīde, meaning "flank or lateral part"). The compound logically describes the lateral surface of a mountain, retaining the original meanings of both morphemes. This construction follows a common English pattern of combining two nouns to create a new, specific term (e.g., "hillside," "riverside").
