Morphology

opsonin = opson (opaque) = opson + in

The base element 'opson' is a specialized combining form not recognizable as a standalone English word to average learners, so the relation to the meaning is not clear.

Etymology

Opsonin comes from the Greek root opson meaning 'sauce' or 'food'. A helpful image is to think of an opsonin as a 'sauce' that coats germs to make them 'tasty' for the immune cells that eat them, so it helps the body remove invaders.
