Morphology

epicardium = epi + cardi + um

Composed of medical combining forms epi- + cardi- + -um meaning roughly 'upon the heart'; the formation is regular but the Greek combining forms and the technical sense make it only partly transparent to an average B1 learner.

Etymology

The word epicardium comes from the Greek parts epi- 'on' and cardium 'heart', and is related to everyday words like cardio and cardiac. So the epicardium is the thin layer that lies 'on' the heart and covers its surface.
