the word terrace originates from the latin 'terra', meaning 'earth' or 'land'. it entered english via old french 'terrace', which referred to a raised platform or a bank of earth. the core semantic link from the ancient root to the modern meaning is the concept of a flattened, shaped area of land. this logic explains its application to leveled ground on a hillside, a row of houses built on such leveled ground, and a paved outdoor area adjacent to a building, all being human-made modifications of the earth's surface.

Structure: terr (earth, land) + ace (noun suffix) terr (from latin 'terra', meaning 'earth, land'), ace (a noun-forming suffix of french/latin origin, often indicating a place or a thing).
