The grammar is the nuts and bolts of a language. It is the foundational stone to get the grip of a language and master it.

So, a sound knowledge and clarity in comprehending English grammar is mandatory for every English language teacher. Just like the nuts and bolts need to be used for the smooth functioning of an engine, similarly sound knowledge of English grammar is a must.

An English teacher could inspire confidence in a classroom scenario when she has comprehended the English grammar. She will be able to re-structure and apply it under different tenses without altering the meaning of the sentences or use the sentences differently to highlight the different meaning implied.

It is only through the understanding of grammar one comes to know the use of ‘will’ and ‘shall’ and tenses and its usage which are the fine points of grammar that in turn reflect the language proficiency of a teacher.

When the teacher is thorough in her grammatical skills, she could ensure the students grasp it too.

e.g.1) The boy sits on the elephant. {Here the subject is the boy, sits is the verb and the elephant is the object)

2) The elephant sits on the boy. { Here the subject is the elephant, sits, the verb and the boy is the object}

Seeing e.g. 1 and 2, just when the word order is changed, it would be a tragic event for the boy in 2 when the elephant sits on the boy.

Another example is: Did you sleep good(adjective) today?

This is a commonly used wrong sentence. In fact it should be as:

Did you sleep well (adverb) today?

As illustrated above, we can infer that just like the driver could drive a car without knowing how a car works yet knowing it well would help him a lot. Therefore, one must understand the mechanics of English grammar.

Moreover, when a student asks to clarify a certain point in grammar, a good English teacher may not be dumbstruck or need not sway away from the topic but explain practically the rules of English grammar with accurate and detailed information.

Whether an English teacher is a native speaker or non-native speaker, he must have a correct knowledge of English grammar. A native speaker though can speak English fluently and correctly, still she may not know how the language works. Whereas, the non-native speaker, a teacher might subconsciously use the grammatical rules of her first language which might be ungrammatical or have ambiguous meaning. In either cases whether we are a native teacher or non-native English teacher, knowledge of grammar does not enable to describe or teach the rules of grammar to a language learner.

For these reasons, we must know the rules of grammar consciously.

Besides, teachers of English to speakers of other language should know grammar as it is one aspect of language learning on which instruction can have a lasting effect. As a teacher we can make a difference in our students’ ability to speak and write grammatical English even if they are no longer the age where they pick the English language naturally. By giving the right grammatical instructions via additional support we can help students increase their grammatical accuracy.
