Function
Definition:
(n.) The act of executing or performing any duty, office, or calling; per formance.
(n.) The appropriate action of any special organ or part of an animal or vegetable organism; as, the function of the heart or the limbs; the function of leaves, sap, roots, etc.; life is the sum of the functions of the various organs and parts of the body.
(n.) The natural or assigned action of any power or faculty, as of the soul, or of the intellect; the exertion of an energy of some determinate kind.
(n.) The course of action which peculiarly pertains to any public officer in church or state; the activity appropriate to any business or profession.
