Language vehicle. The emergence of language in the pursuit of expression. The main function of language is to convey one's thoughts to many. From the earliest times of human civilization, different peoples in different parts of the world used to communicate with each other through their specific symbolic sounds. It is not possible to fully express their feelings. Then , in a corner, the man's mouth opened. People then started uttering broken sounds. And language has been created over time from the source of those sounds emanating from human mouth. However, it is not known when , where or how the language was created. Language is a meaningful sound or set of sounds emanating from a person's mouth . To utter these sounds, vocal organs like voice , tongue , palate , lips , teeth , nose etc. need help. No sound or combination of sounds uttered by these vocabularies alone can create a language. In order to be a language , one has to express the meaning of a sound or a set of sounds somewhere.
