Etymology: The word is the plural of "piloti", borrowed from French, where it came from Middle French "pilot", meaning "stake" or "pile": a long post driven into the ground to support a structure. That sense points back to the same stock as "pile" in the sense of a heap of timber, and it is the original meaning that matters here. Architects took the French term for a driven support and applied it to a building that stands on slender columns rather than solid foundations. The "pilot" in this sense is entirely separate from the word for a person who steers a ship or aircraft. The two only look alike because they came into French from different sources, and English readers who know the nautical word may be surprised to learn that this architectural term has nothing to do with steering. Here, "pilotis" names the thin columns themselves, and the building they hold up.
