   meqodos method, investigation following after; meta` after +

   1. An orderly procedure or process; regular manner of doing

      --Addison.
      [1913 Webster]

                                                  --Shak.
      [1913 Webster]

            All method is a rational progress, a progress toward
            an end.                               --Sir W.
                                                  Hamilton.

   4. A technique used in acting in which the actor tries to
      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 (17 December 2009):

method

    The name given in Smalltalk and other
   object-oriented languages to a procedure or routine
   associated with one or more classes.  An object of a
   certain class knows how to perform actions, e.g. printing
   itself or creating a new instance of itself, rather than the
   function (e.g. printing) knowing how to handle different types
   of object.

   Different classes may define methods with the same name
   (i.e. methods may be polymorphic).  The term "method" is used
   both for a named operation, e.g. "PRINT" and also for the code
   which a specific class provides to perform tha
   t operation.

   Most methods operate on objects that are instances of a
   certain class.  Some object-oriented languages call these
   "object methods" to distinguish then from "class methods".

   In Smalltalk, a method is defined by giving its name,
   documentation, temporary local variables and a sequence of
   expressions separated by "."s.
