Where does “seafood” come from?

I need to work through this etymology chain carefully. Looking at the chain provided, I notice there are some problems: - "food" comes from: English food ← Middle English fode ← Old English fōda - But then the chain jumps to unrelated words (sedes, pat-, pandemic, sed-, δῆμος) - These appear to be fragments from different etymologies mixed together The chain seems corrupted or incomplete. It shows the ancestry of "food" clearly (English → Middle English → Old English), but then includes unrelated etymological material that doesn't connect to "seafood." For "seafood" specifically, the word would be: - English seafood (sea + food, a modern compound) - Where "food" derives from Old English fōda - And "sea" derives from Old English sǣ However, I cannot construct an accurate one-sentence etymology following your
