Gardner's definition of motivation is best known and
frequently quoted. He defines motivation to learn a L2
(Gardner, 1985: 1) as "the extent to which the individual
works or strives to learn the language because of a desire to do
so and the satisfaction experienced in this activity". Gardner
(Tremblay & Gardner, 1995) explains that this definition
includes three components: (a) effort expended to achieve a
goal, (b) a desire, to learn the language, (c) satisfaction with
the task of learning the language.
