Mountainously → It is formed from "mountain" (from Old French *montaine*, meaning a large natural elevation of the earth's surface) and the suffix "-ously" (meaning in a manner of). The word "mountainously" describes something that is in a manner characteristic of mountains, often referring to terrain or landscapes that are hilly or steep.
Picture a landscape that is 'in a manner of' mountains — 'mountain' refers to the large elevations, and '-ously' indicates how something is done. This helps you remember that 'mountainously' describes something that resembles or is like mountains.
