The other side of lexical errors in oral expression

When learning a new notion a new knowledge a way of acting or behaving man always makes mistakes. This justifies the fact that current foreign language teaching methods with the exception of auditory-oral and situational methods regard error as a natural phenomenon in learning as inseparable from this activity. This is a belief held by Perdue (1980) and Brown (1987) among other didacticians in the clearest terms: ''Indeed if learning French as a foreign language is a cognitive activity that consists in making and verifying hypotheses about its structures the learner will inevitably make mistakes'' says the former; while the latter asserts that in learning a language whether first language (L1) second language (L2) or foreign language (L3) learners always make mistakes.Learning French as a second language is always accompanied by errors whatever the reference language and whatever the learners' abilities. These errors appear both orally and in writing.
