bandfish comes from band + fish, named for its long, ribbon-like (banded) body; band from Old French bande ('strip, edge'), of Germanic origin. Morphologically, the word is transparent as a compound: its parts remain visible in the modern spelling, while the older history of those parts supplies the deeper ancestry. In modern use, the noun sense is "a small elongated red marine fish of the family Cepolidae", which keeps the etymology connected to the word's present dictionary value rather than treating it as a merely historical label. The wider word family includes related English forms such as band, fish, showing how the same base continues to support neighboring English vocabulary. The principal historical forms in the chain include Old French bande, which anchor the explanation in named linguistic material.
