Grammar is usually defined as the system of language. Though it is often described as the rule of language, in fact no language has rules. If we use the word rules, we suggest that somebody created the rule first and then spoke the language. But language didn’t start like that. Language begin to exist when people started making sounds which evolved into words, phrase and sentences.No commonly spoken language is fixed. All language change over time. What we call grammar is simply a reflection of a language at a particular time.

However if you are keen upon learning English language, it is necessary to learn grammar, as it can help you to learn a language more quickly and more efficiently. It’s important think of grammar as something that can help you, like a friend. Understanding the grammar of a language would enable you to understand many things yourself, without having to ask a teacher or look in a book.

So think of grammar as something good, something positive and something that you can use to find your way like a sign post or a map.
