Where does “codfish” come from?

I appreciate the detailed instructions, but I need to flag a critical issue: the etymology chain provided doesn't support an entry for "codfish." The chain traces: English fish ← French fiche ← French ficher ← Proto-Germanic fiskōną ← Proto-Indo-European pisḱ- ← Proto-Indo-European h₂ep- ← English pandemic ← English pandemic This chain explains the word "fish," not "codfish." It also contains logical problems (English words shouldn't appear as sources for Proto-Indo-European roots; the chain loops back on itself at the end). To write an accurate one-sentence origin summary for "codfish," I would need: 1. A valid etymological chain specifically for "codfish" (likely: English codfish ← English cod + English fish, with separate chains for each component) 2. Clarification of what the provided chain is meant to

codfish (English): A cod; The flesh of the cod as food
