Morphology

arginine = argin + ine

The suffix '-ine' signals a chemical class, but the stem 'argin' is not a recognizable English base and the specific meaning (an amino acid with nutritional/physiological roles) cannot be derived by an average B1 learner.

Etymology

Arginine can be remembered by its special chemical part: the related word guanidine comes from guano, 'bird droppings', where chemists first found it. That guanidino part helps arginine do important jobs in the body, like helping blood flow and supporting fertility.
