Downstairs → It is formed from "down" (from Old English "dūn", meaning downward or lower) and "stairs" (from Old English "staer", meaning a step or stair). The word "downstairs" refers to the lower level of a building, indicating a position that is downward from another level.
Think of going 'down' ('dūn') to the 'steps' ('staer') of a building — that's why downstairs means the lower level.
