Definition
"Discretional" is a synonym of "discretionary," meaning something done or used according to one's own judgment or choice. It emphasizes the freedom to decide based on individual assessment, unlike something mandatory. Think of a teacher who has the discretional authority to adjust grades, or a manager with discretional power to allocate resources. The difference in usage is subtle, but "discretionary" is much more common. Both words highlight autonomy in decision making. Discretional choices are powered by the individual.
