 There have been two schools of thought when it comes to errors analysis and philosophy, the first one, according to Corder (1967) linked the errors commitment with the teaching method arguing that if the teaching method was adequate, the errors would not be committed, the second school believed that we live in an imperfect world and that errors correction is something real and the applied linguist cannot do without it no matter what teaching approach they may use.Chomsky (1965) made a distinguishing explanation of competence and performance on which, later on, the identification of mistakes and errors will be possible, Chomsky stated that ‘’We thus make a fundamental distinction between competence (the speaker-hearer's knowledge of his language) and performance (the actual use of language in concrete situations)’’ ( 1956, p. 4).In other words, errors are thought of as indications of an incomplete learning, and that the speaker or hearer has not yet accumulated a satisfied language knowledge which can enable them to avoid linguistics misuse.
