Morphology

inotropic = inotropy (semi-transparent) = ino + tropy + ic

Formed by the productive suffix '-ic' from the noun 'inotropy', yielding an adjective meaning 'relating to inotropy'.

Etymology

Inotropic comes from Greek parts ino- meaning 'muscle' and -tropic meaning 'to turn' or 'to change', so an inotropic drug changes how strongly the heart muscle contracts.
