Middle English gele English jelly Proto-Indo-European *péysks Proto-Germanic *fiskaz Proto-West Germanic *fisk Old English fisċ Middle English fisch English fish English jellyfish From jelly + fish. From being an aquatic creature (i.e. fish) that is gelatinous (“jelly”). Despite the name, jellyfish are not biologically classified as fish. The term appeared in the mid-19th century and displaced various older terms such as sea jelly (now much less common), blubber/sea blubber, nettle/sea nettle (both now referring to specific jellyfish species), and, in scientific literature, medusa.
