Importance of Grammar

Let’s work this backwards.
1. The main aim of language is to communicate.
2. To communicate you need to be able to form sentences.
3. Sentences are made of words and phrases.
4. However, words and phrases placed randomly do not make sense and hence no communication is possible.
5. Grammar gives structure to a sentence. Grammar tells you where the words and phrases should go in a sentence.
6. I, therefore, do not understand the reluctance to learn grammar early on.

Communication does not merely mean conveying needs or asking for directions or saying how many children you have. The goal is to convey thoughts and ideas.
This obviously takes time. But that is no excuse to eschew grammar.

Because humans pick up basic patterns naturally and without much effort. These patterns are generally sufficient for simple to intermediate level of activities. However, for more advanced tasks a better understanding of patterns is required. And that means more effort. Hence, study of patterns is considered difficult. And since there is a common tendency to achieve without effort, study of patterns such as, mathematics and grammar, is presented as something that is esoteric and not essential for normal routine.

Incroyable! C'est ridicule.
