Morphology

myocardium = myo + cardium

The components 'myo' and 'cardium' are not standalone English words and require specialized knowledge to understand their meaning related to heart muscle.

Etymology

Myocardium breaks into myo- meaning 'muscle' and -cardium meaning 'heart'. So myocardium is the heart's thick muscle layer that contracts to pump blood.
