Morphology

epinephrin = epinephrine (opaque) = epi + nephr + in

Formed from Greek combining elements (epi- + nephr- + -in) that are not productive or familiar to average learners, so the meaning is not derivable from its parts.

Etymology

Epinephrin comes from Greek parts epi- 'upon' and nephros 'kidney', so it originally meant 'upon the kidney', the place where the adrenal gland sits. That's why epinephrin (also called adrenaline) is the hormone the body makes in danger to speed up the heart and give a quick burst of energy, the 'fight or flight' response.
