      identify with the individual personality of the specific
      character being portrayed, so as to provide a realistic
      rendering of the character's role. Also called the
      Method, method acting, the Stanislavsky Method or
      Stanislavsky System.
      [PJC]

   Syn: Order; system; rule; regularity; way; manner; mode;
        course; process; means.

   Usage: Method, Mode, Manner. Method implies
          arrangement; mode, mere action or existence. Method is
          a way of reaching a given end by a series of acts
          which tend to secure it; mode relates to a single
          action, or to the form which a series of acts, viewed
          as a whole, exhibits. Manner is literally the handling
          of a thing, and has a wider sense, embracing both
          method and mode. An instructor may adopt a good method
          of teaching to write; the scholar may acquire a bad
          mode of holding his pen; the manner in which he is
          corrected will greatly affect his success or failure.
          [1913 Webster] Methodic

The Free On-line Dictionary of Computing (19 January 2023):

method

    In object-oriented programming, a function that
   can be called on an object of a given class.  When a method is
   called (or invoked (method invocation)) on an object, the object
   is passed as an implicit argument to the method, usually
   referred to by the special variable "this".  If the method is not
   defined in the object's class, it is looked for in that class's
   superclass, and so on up the class hierarchy until it is
   found.  A subclass thus inherits {inheritance all the methods
   of its superclasses.

   Different classes may define methods with the same name
   (i.e. methods may be polymorphic).

   Methods are sometimes called "object methods" or "instance
   methods".  "Class methods" are methods that operate on objects
   of class "class".  "Static methods" are not methods but normal
   functions packaged with the class.
