The benefits of corpus approach is that learners will acquire the form of the foreign language because they are engaged in exploring aspects of the native language on the basis of authentic content. Traditional teaching is teacher-led where the teacher presents grammatical rules or patterns to the student and later tests whether the student has acquired those rules. On the other hand there is Corpus Based Aproach that gives a degree of independence to the language learner by providing them with a computer assistant, to answer whatever questions the learner comes up with during their reading or writing. A concordancer can act as a viable assistant to the learner by allowing the learner to quickly encounter a range of real-text examples of a linguistic phenomenon, the learner can generalise over the examples and derive their own usage rules
