Morphology

Monotremata = mono + trem + ata

This is a Latinized scientific taxon built from classical combining forms meaning 'single' and 'hole', but the structure is not transparent to an average English learner.

Etymology

Monotremata comes from the Greek parts mono- 'one' and trema 'hole', so it means 'single opening'. That's why the egg-laying mammals like the platypus and echidnas are called Monotremata: they have one body opening for both reproduction and waste.
