Morphology

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

The adjective is built from the Latin stem fiss- 'split' plus '-ile'; the literal sense 'able to be split along planes' aligns with the components, but the combining stem is not a common standalone English word.

Etymology

The word fissile comes from the Latin root fiss- meaning 'to split', the same root used in fissure, which means 'a crack'. So, fissile describes materials that easily split along natural layers or cracks.
