Kiswahili and English are the Official languages, however the former is the national language. While Kiswahili is the medium of instructions at primary school level; English is medium at Higher educational levels.
Kiswahili, the national language, excites a listener in terms of the way some people from the different ethnic groups speak fast including some slang's while other members from other tribes speak slowly and carefully.
Many people treat language as one of the facts of life, like breathing, and it is true that social life as we know, it does not exist independently of language. In those countries that lack important linguistic minorities, language problems may assume importance only frequently, but in multilingual countries like Tanzania the situation is quite different. Here a number of factors have contributed to a situation in which the use of a particular language comes to be characteristic of a particular social domain, in much the same way that domains are characterized in England by varieties of English. In time the languages themselves take on the complex of emotions, prestige, etc. that are associated with the domains themselves. Thus, local languages like Kisukuma or Kigogo may be linked with the rural homestead or with traditional values; Swahili may be linked with town life or trade and English with government service, the professions and high status jobs. At a still later stage the languages acquire symbolic status and may then serve political ends. Thus, one may condemn the use of local languages as encouraging tribalism or praise them as expressing the true spirit of African-ness; One may condemn Swahili as divorced from local culture or praise it as transcending tribalism; one may condemn English as a colonialist language or praise it as making for the efficient operation of government services. One does not commonly find language as an overt symbol of political action. For many years it may lay dormant and be active along with or independently of other factors by issues of local or national importance apparently unconnected with language. Far more commonly one finds it functioning as one of a number of variables signaling socio-economic status in the community in various subtle and pervasive ways.
