Knowledge and application of grammar rules is significant to every English language learner. This is especially significant because nowadays, learners of the target language are confronted with varied venues where they may utilize English for communication or mere expression of their thoughts and feelings. For instance, learners are also Facebook users who post statuses which are often in the target language. In the process, they commit errors. Errors are basically committed because the learner has had experiences with another language. The complexity of learning the new language may conflict with the structure of his native language. Thus, errors appear as learners attempt using or producing the target language. When errors occur, it is the role of the language teacher to deal with these errors by devising some strategies after the conduct of error analysis. From being looked at as a problem that should be eradicated, errors are now considered as a device that learners use and from which they can learn.
