What's the difference between function and role?

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.
  • (n.) A quantity so connected with another quantity, that if any alteration be made in the latter there will be a consequent alteration in the former. Each quantity is said to be a function of the other. Thus, the circumference of a circle is a function of the diameter. If x be a symbol to which different numerical values can be assigned, such expressions as x2, 3x, Log. x, and Sin. x, are all functions of x.
  • (v. i.) Alt. of Functionate

Role


Definition:
