Morphology

immunodiffusion = diffusion (semi-transparent) = immuno + diffuse + ion

The parts 'immuno-' (relating to immune) and 'diffusion' are interpretable, but the compound denotes a specialized laboratory technique that is not obvious to general learners.

Etymology

Immunodiffusion breaks into immuno- meaning 'related to the immune system' and diffusion meaning 'spreading out', like a smell moving through a room. So the name tells you what the test does: immune particles spread in a gel and form visible lines where they meet.
