Grammar is the set of rules that describes how words and groups of words can be arranged to form appropriate sentences in a given language. The ability to arrange the words of a second language into meaningful sentences is profoundly basic to communicating effectively in that language. Every language has its own set of grammar rules therefore it is important to get a good grasp of the grammar rules of the non- mother tongue language that one wishes to learn, more so if the language happens to be English . Needless to say, that incorrect use of grammar in the English language will certainly be a cause for embarrassment in certain quarters. However , one can take heart in the fact that even the most competent users of the English language do flounder one in a while with its grammar . Learning to use the grammar well could take some time , but rest assured it would well be worth the time and effort.
