A national language is a language (or language variant, e.g. dialect) that has some connection—de facto or de jure—with a nation. ... One or more languages spoken as first languages in the territory of a country may be referred to informally or designated in legislation as national languages of the country. National language is a driving force behind unity of the nation's people, and makes them distinct from other nations – provided you give your language respect. Giving respect to your national language means that it should be one's primary language, as well as the preferred source of communication at every level. Language can have scores of characteristics but the following are the most important ones: language is arbitrary, productive, creative, systematic, vocalic, social, non-instinctive and conventional. These characteristics of language set human language apart from animal communication.
