Morphology

fission = fiss + ion

Built from the combining form 'fiss-' plus the noun-forming suffix '-ion'; 'fiss-' is not a standalone English word, so learners cannot reliably derive the biological sense from the components alone.

Etymology

Fission comes from the Latin findere, meaning 'to split'. In biology it keeps that image: one cell splits in half to make two new cells, so fission is the name for this simple way of reproducing.
