Morphology

crayfish = cray + fish (semi-transparent) = cray + fish

The word is visibly a compound of 'cray' + 'fish', so learners can tell it's an aquatic animal, but 'cray' is less familiar and 'fish' is biologically misleading because a crayfish is a crustacean, not a true fish.

Etymology

The word crayfish comes from an old French word escrevisse, now écrevisse, which English speakers heard as 'cray' or 'craw' and later added the familiar word fish. So the word crayfish is used for small, lobster-like animals found in rivers and streams.
