Morphology

sperm + whale

The compound is structurally transparent as a noun–noun composition (a kind/kind of whale), so the modifier indicates a property of the whale. However, the modifier 'sperm' here refers to spermaceti (a technical substance) rather than the common B1 meaning 'reproductive cell', so learners who only know the everyday sense of 'sperm' are likely to be confused and not infer the specific biological referent without prior exposure.

Etymology

The name sperm whale comes from a waxy oil found in the whale's very large head, once called 'spermaceti'. Early sailors thought this oil looked like sperm, so they named the animal the sperm whale, and that is why we still call it that today.
