Etymology

The word "goldfish" is a straightforward compound of "gold" (referring to the fish’s characteristic orange-gold coloration) and "fish" (denoting its biological class). Originating in early 17th-century English, it reflects the selective breeding of carp (Carassius auratus) in China, where vibrant color mutations were prized. The term’s simplicity mirrors its function—describing a domesticated aquatic animal distinguished by its hue.
