Morphology

diffusion = diffuse (transparent) = diffuse + ion

The scientific sense is the noun form of the verb 'diffuse' describing the physical process, so the derivation is clear.

Etymology

Diffusion comes from Latin parts dif- 'apart' and fundere 'to pour', so it once meant 'to pour out' or 'spread out', the same root you see in fuse. In science, imagine a crowd moving from a busy place to an empty one — molecules move from where there are many to where there are few, and that movement is called diffusion.
