" A national language is the structure of several forms of a language such as the fictitious language, accepted conversational varieties of the language, and dialects. In the course of the configuration of a national language, the relationship between literary language and vernacular endures a considerable change. The national literary language is the most important developing form of a language; it regularly displaces the dialects that dominated the earlier stages of language development, especially in oral communication . At the same time, the literary language gains wider reception and application and its functions become more complex. The literary form of a language becomes leading as a result of the increasing complication and development of the national culture of a people. The English language is one of those languages that transformed and developed to be countrywide over ages. This growth to be a national language goes over seven ages."
