Morphology

family + Megatheriidae

The headword 'family' clearly signals a taxonomic grouping, so a learner who knows that word can infer this phrase names a biological family. However, 'Megatheriidae' is a specialised Latin taxon name that does not reveal its referent (large extinct ground sloths) to a typical B1 learner, so the full, specific meaning is not predictable from the constituents alone.

Etymology

Family Megatheriidae comes from old Greek words: mega meaning 'big' and therion meaning 'beast', so it creates the image of a 'huge beast' — the giant ground sloths that lived in South America. That's why the name refers to the family of very large, extinct ground sloths.
