What is Grammar after all?

What is Grammar after all?

Grammar is all about forms and functions.  Of course, it is also about punctuation.  Therefore, grammar is like a skeleton that support a body.  Without it, the body just crumples down into a mass like a dough.  Grammar is also like a mould which gives the shape. 

Hence a good knowledge of grammar does not guarantee you to speak on any specific topic.  To speak on any specific topic, you need the knowledge or to be well-informed of the concerned topic.  For example, if you know nothing about the mole rat, can you talk about this animal?

Hence, being able to engage yourself in the conversation or not should not mix up with the knowledge of grammar.  Those who advocate communicative English to learn English claims that  grammar is not to be learnt deductively or explicitly.  Am I right?  Hence learning grammar is more or less ditched out from most of the English classroom scenario.

        In the federation of Malaysia, there are only ten marks allocated to the context tested on grammar in the PT3 public examination.  I wonder if there is any school in the whole-wide world still teach grammar item by item.  Then allocate at least 30 marks on grammar.   Ever since the introduction of communicative English twenty over years ago, grammar learning has been marginalised and losing out in the English learning environment. 

        Well, are the students who have gone through this process able to communicate better in speaking and writing English?
