The word "top" traces back to the Old English word "topp", which referred to the highest point or uppermost part of something. It shares connections with several Germanic languages, such as Old Norse "toppr" and Old High German "zopf".
The term "floor" comes from the Middle English word "flor", which originated from the Old French word "flur". This ultimately stems from the Latin word "flōrem", meaning "flower" or "blossom". In the context of a building, "floor" originally referred to the surface upon which one walks, thus likening it to the ground or foundation of a structure.
