Morphology

family + Rheidae

The phrase is fully compositional: 'family' as a taxonomic grouping combined with the proper name 'Rheidae' directly yields the meaning 'the taxonomic family Rheidae (the group of large flightless South American birds)'. This follows standard biological naming conventions found across languages, so a B1 learner who knows both constituents would readily understand it.

Etymology

Family Rheidae comes from the common bird name rhea, a large, flightless South American bird. Scientists add the ending -idae to show a 'family' of related animals, so the phrase means 'the family of rheas'.
