Language and society

Language is innate and nothing more, once you are privileged to stay and communicate with the native speaker then learning any language will be so easy, language acquisition is the innate capabilities of a child to inherit his mother tongue naturally with or without the influence of her parents while language learning could be done in the four walls of the classroom or through listen with rapt attention to native speaker of the language. So the desire to be with more than a language can not be over emphasize.

Though, research has shown that language is a system of communication where sound or
signs/signal convey objects, actions and ideas. Dated back in the history of language; many centuries when the first Men were using language, it is primarily spoken not written. But
the development of the writing medium/ materials and later the printing system went a
long way is the dissipation of knowledge and without which humans would
have remained in the dark about the ways of life and the thought processes of
their ancestors. Language is the key to human lives. Without language, human race would have in darkness, there won't be any developments whosoever. Thus, the existence of language eliminate misunderstanding by using it as an instrument to transfer communication among
people in an given society. source

What is more important; the acceptability of a language's utterance or its grammaticality?
