Morphology

hemolysin = hemolysis (semi-transparent) = hemo + lysis + in

Formed from the biomedical noun 'hemolysis' with the protein-forming suffix '-in'; the composition is regular but relies on specialized combining forms unfamiliar to general learners.

Etymology

Hemolysin comes from two parts that mean 'blood' and 'to break': hemo- (the same root as in hemoglobin) and -lysin ('something that breaks'). So, a hemolysin is a substance that breaks red blood cells and releases hemoglobin.
