Feasibility \Fea"si*bil*ity\n.; pl. {Feasibilities} (-tiz). [from {Feasible}] The quality of being feasible; practicability; also, that which is feasible; as, before we adopt a plan, let us consider its feasibility. Men often swallow falsities for truths, dubiosities for certainties, possibilities for feasibilities. --Sir T. Browne.
