From The Collaborative International Dictionary of English v.0.48:

Variable \Va"ri*a*ble\, n.
   1. That which is variable; that which varies, or is subject
      to change.
      [1913 Webster]

   2. (Math.) A quantity which may increase or decrease; a
      quantity which admits of an infinite number of values in
      the same expression; a variable quantity; as, in the
      equation x^2 - y^2 = R^2, x and y are variables.

          expected, especially the parts between the trade-wind
          belts.
          [1913 Webster]

   Independent variable (Math.), that one of two or more
      variables, connected with each other in any way whatever,
      to which changes are supposed to be given at will. Thus,
      in the equation x^2 - y^2 = R^2, if arbitrary
      changes are supposed to be given to x, then x is the
      independent variable, and y is called a function of x.
      There may be two or more independent variables in an
      equation or problem. Cf. Dependent variable, under
      Dependent.
