Morphology

fusion = fuse (transparent) = fuse + ion

Derived from 'fuse' meaning 'join'; here applied to the technical process of nuclei joining, so the morphological relation is clear though the sense is specialized.

Etymology

The word fusion comes from the Latin fundere 'to pour' and is related to the English verb fuse, so you can imagine tiny parts 'pouring' together. That image helps: nuclear fusion is when parts of atoms join into one heavier part and release a lot of energy.
