Morphology

adrenalin = adrenal (semi-transparent) = adrenal + in

Formed from 'adrenal' + the substance-forming suffix '-in'; the biomedical formation is clear but technical for general learners.

Etymology

Adrenalin comes from the parts ad- meaning 'near' and renal meaning 'kidney', because the small adrenal glands sit on top of your kidneys. So adrenalin is the quick energy chemical your body makes when you are scared or excited, and it makes your heart beat faster and gives you a sudden boost.
