Morphology

phytohaemagglutinin = haemagglutinin (opaque) = phyto + haemagglutinin

The formation is technical and relies on specialized combining forms, so learners are unlikely to infer the toxic-bean sense from the parts.

Etymology

Phytohaemagglutinin comes from phyto- 'plant', haemo- 'blood', and agglutinin 'to stick together', like 'glue'. So, the name warns that this is a plant protein found in some raw beans that can make cells clump and cause stomach illness if the beans are not cooked properly.
