Morphology

facultatively = facultative (semi-transparent) = facultative + ly

Forming an adverb with the productive suffix '-ly' from the adjective 'facultative' is a straightforward and regular derivation.

Etymology

Facultatively comes from the Latin word facultas, meaning 'ability' or 'opportunity', and it shares the same root as the English word faculty. So, to do something facultatively is to do it by 'choice' or when you can, not because you must, which is why we say some organisms live facultatively in different conditions.
