Morphology

mastiff + bat

The compound is a type-of-bat named with another animal term: if a learner knows 'mastiff' (a large, heavy dog) and 'bat', they can infer this is a bat with mastiff-like qualities (e.g. relatively large/robust), so the basic category is compositional. However, the specific descriptive details (soft-furred, chocolate-brown, folded ears, ground-running behaviour) are not predictable from the constituents, and many B1 learners may not know the breed name 'mastiff', reducing immediate transparency.

Etymology

The name mastiff bat may come from the dog mastiff, because these bats are big with a short face and sometimes 'run on the ground' like a dog. That's why people used mastiff to describe this bat, and the name now refers to this brown bat that can run as well as fly.
