In addition, early childhood is a time for learning language development. By age three and above, children are already putting words together into simple sentences, mastering grammar, and undergoing a process of learning vocabularies. Young children also show considerable grammatical awareness in how they put words together into sentences. Sometimes this causes children to overstress the meanings of words beyond their appropriate use or to over regularize grammatical rules by applying them to irregular forms.
Till today, American English has never had a strict spoken standard that is considered correct, as most other European languages have. Today the spoken standard in American English is best defined as the relative absence of characteristics (such as word choice or pronunciation) that might identify the speaker as coming from a particular region or social group. National newscasters and other broadcast personalities often adopt this speech type in public, as do many Americans in formal settings such as schools, courts, and boardrooms. Then the case/question above is English should not obey rules of grammar.
In understanding this case one has to understanding the meaning of grammar and rules governing it. Therefore, grammar is the field of linguistics that covers the rules governing the use of any given natural language. It includes morphology and syntax, often complemented by phonetics, phonology, semantics and pragmatics. Its also a theory of language structure rather than a description of actual sentences. Any language is governed by rules; otherwise it ceases to be a language. But within them, one can say many different sentences and express oneself.
A fully explicit grammar exhaustively describing the grammatical constructions of a language is called a descriptive grammar, as opposed to linguistic prescription which tries to enforce the governing rules how a language is to be used. Rules of language grammar sometimes correspond to universal thought forms, that is, it has to conform to some recognized patterns. However, standard language is usually more appropriate in formal situations because people have come to expect it on those occasions. Moreover, in my own opinion, I think English language should not obey the rules of grammar.
Since, what is important is understanding and be able to express oneself to people. For instance, like the American English of today that do not follow rules of grammar and yet people understand and prefer it other European languages. In conclusion, English might obey the rules of grammar and in another view it might not obey such rules. What matters is where one is expressing oneself (formal or informal gatherings).
