As far as English grammar is concerned, some people believe it is easy to learn for it is intuited, understood through what people say, without having to use structural exercises. Their opponents, however will argue that we have to learn how grammar rules work for accurate language. Of course, sometimes it can be done by comparing the rules of English grammar with our own ones (native language rules), taking advantage of all the similarieties that facilitate our learning. But on the other hand, the discrepancies may make it difficult. Although, English grammar is fraught with a lot of problems which the learner has to overcome (tenses, countable and uncountable nouns, conditionals, the article system, the possessive apostrophe.....), it can be mastered by systematic work on it.
