Morphology

coarctation = coarct + ation

Formed from a bound combining form 'coarct-' plus the noun-forming suffix '-ation'; the root is not a standalone English word and the term is a specialized medical item, so learners cannot transparently infer the meaning from familiar parts.

Etymology

Coarctation comes from the Latin coarctare, which means 'to press together', and you can see the same idea in the English word constrict. So a coarctation is when a blood vessel or other tube is 'pressed tight' or narrowed.
