Morphology

fissile = fission (semi-transparent) = fiss + ile

Formed from the Latin combining stem fiss- 'split' plus the adjectival suffix '-ile'; because fiss- is not a standalone English word learners may not reliably infer the meaning, though knowledge of 'fission' or 'fissure' helps.

Etymology

The word fissile comes from the Latin root fiss- meaning 'to split', and it is the same root as fission, the process where an atomic nucleus splits and releases energy. So, fissile means able to be split in a nuclear reaction.
