Morphology

infeasible = feasible (transparent) = in + feasible

The negative prefix 'in-' combines straightforwardly with 'feasible' to mean 'not feasible'.

Etymology

Infeasible starts with the prefix in- meaning 'not' and comes from a root that means 'to do', the same root you see in factory, a place that makes things. So infeasible means 'not possible to do', which is why we use it for plans or ideas that cannot be done.
