Morphology
eutrophication = eutrophic (opaque) = eu + troph + ic + ation
The change from 'eutrophic' to 'eutrophication' is regular, but the base adjective is technical and the full meaning is not readily recoverable for an average learner.
Etymology
Eutrophication comes from Greek parts eu- meaning 'good' and troph meaning 'nourishment' or 'food', so it literally says 'well fed'. That's why eutrophication describes what happens when a lake or river gets too much 'food' (nutrients): plants and algae grow too much and then use up the oxygen, harming animal life.
