Nunan  defines strategies as “the mental and communicative procedures learners use in order to learn and use language.
Underlying every learning task is at least one strategy.” Richards and Schmidt  define strategy as “procedures used in learning,
thinking, etc., which serves as a way of reaching a goal. In language learning, learning strategies are those conscious or unconscious
processes which language learners make use of in learning and using a language.” The definitions provided for learning strategies
by scholars all have one point in common and that is facilitating learning for learners. Nevertheless, they are in disagreement about
issues like whether such strategies are conscious and so describable and then teachable, and also what variables are involved in
strategy use by language learners have resulted in various contentions on the part of researchers.
