Morphology

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

The ML sense is an extension of the physical/statistical notion of diffusion, but the technical mechanism and application require domain knowledge, so the derivation is not fully transparent to general learners.

Etymology

Diffusion comes from Latin parts dif- 'apart' and fundere 'to pour', which gives the sense of things spreading out. A helpful way to remember the machine learning use is to imagine a noisy 'pour' of dots that slowly change and become a clear picture — that gradual change is called diffusion.
