Morphology

dissociation = dissociate (semi-transparent) = dis + associate + ion

The noun is a regular process/result formation from the verb 'dissociate'.

Etymology

Dissociation comes from Latin parts dis- 'apart' and soci- 'companion', the same root as associate. In chemistry, dissociation is when a molecule 'parts from' its partner and splits into smaller, separate parts.
