Morphology

hemagglutination = hemagglutinate (opaque) = hema + agglutin + ation

The noun is a regular derivation from the verb 'hemagglutinate' using the productive suffix '-ation'.

Etymology

Hemagglutination breaks into hema- meaning 'blood', as in hemoglobin, and agglutin- meaning 'to glue', like 'glue'. So hemagglutination is literally 'blood-gluing', which is why it means red blood cells clumping together.
