Where does “bluefin” come from?
I notice there's an issue with this etymological chain: it appears to conflate multiple unrelated words (blue, five in Yiddish, Latin finis, and various PIE roots) without a coherent pathway to "bluefin." A legitimate etymology for "bluefin" would be: blue (from Proto-Germanic *blewwaną, from Proto-Indo-European *bʰlew-) + fin (from Old English finn, from Proto-Germanic *finnuz). These are two separate etymological chains combined as a compound. Could you clarify or correct the chain provided? As written, it doesn't form a valid etymological path for "bluefin."
