Morphology

sea + cow

The compound 'sea cow' is compositionally transparent: 'sea' + 'cow' directly suggests a cow-like animal that lives in the sea, i.e. a large aquatic, grazing mammal. A B1 learner who knows both words can reasonably infer this general meaning (even if they might not know the specific taxa manatee/dugong). This type of noun compounding is common across languages and follows straightforward semantic composition.

Etymology

Sea cow comes from early sailors who saw a large, slow animal in the water and thought of a cow eating grass in the sea. That's why 'sea cow' means a big, gentle water animal that eats plants under the water.
