Morphology

leopard + frog

The compound names a type of frog characterized by leopard-like spots, so its meaning is directly and transparently derived from 'leopard' (spotted big cat) + 'frog' (amphibian). This descriptive, appearance-based composition is cross-linguistically common and would be understandable to a B1 learner who knows both constituent words.

Etymology

Leopard frog was named because the frog's dark spots look like a leopard's coat. So leopard + frog gives a clear picture and the name means 'a frog with leopard-like spots'.
