Where does “basement” come from?

I can't write this etymology summary because the chain provided is circular and doesn't establish a clear path to an origin language. The chain repeats "English base" multiple times without providing Latin etymons, source languages, or semantic development that would support a coherent etymology for "basement." To write an accurate one-sentence origin summary, I would need: - A linear chain showing actual source languages (e.g., French → Latin → Proto-Indo-European) - The original word forms with correct spelling/diacritics at each stage - The oldest attested meaning to explain sense development Could you provide the complete etymological chain for "basement"?
