Morphology

fissionable = fission (transparent) = fission + able

The adjective is formed by adding the productive suffix '-able' to the noun 'fission', yielding 'capable of undergoing fission'.

Etymology

Fissionable comes from fission ('a split') and the ending -able ('able to be'), so it describes something that can be split. In science, a fissionable atom or material is one that can be split to release large amounts of energy.
