Etymology: "Jewelfish" is a plain compound of "jewel" and "fish," and the name describes the fish's appearance: its bright, gem-like colouring. The jewel half comes from Old French "jouel," a diminutive-style word for a trinket or ornament, which passed into English in the Middle Ages and was once used for any valuable item, not only gemstones. The fish half is the ordinary Old English "fisc," so the word is a straightforward descriptive pairing rather than a term with a dramatic history. The name is a common-sense label for aquarium fish that show jewel-like hues and sharp, distinctive markings. Its meaning rests entirely on the picture the two parts create together, with no special twist in the sense of either word.
