Morphology

unfeasible = feasible (transparent) = un + feasible

The adjective is formed by straightforward negation of 'feasible' with the productive prefix 'un-'.

Etymology

The word unfeasible is made of un- (meaning 'not') and feasible, which comes from an old root meaning 'to make' or 'to do', the same idea you find in factory. So unfeasible means 'not able to be done', which is why we use it for plans or ideas that cannot be achieved.
