Where does “aboriginal” come from?

I can't write this etymology sentence because the chain you've provided appears to be corrupted or circular—it cycles repeatedly through the same three terms (Aboriginal, aboriginal, aldehyde) without establishing a clear etymological path to an older language origin. A valid etymology chain needs to progress backward through actual source languages (like Latin, French, Arabic, etc.) with genuine historical attestations. Could you provide the correct chain showing the actual source languages and their original forms?
