An official language is one designated by governmental decree to be the official means of communication of the given state in government, administration, law, education and general public life. Kloss (1968) distinguishes between endoglossic and exoglossic official languages, whereby an endo- glossic official language is one indigenous to the state, e.g. English in England, French in France, whereas an exoglossic one is imported, e.g. English in Kenya, Ghana, Sierra Leone, or French in Zaire, and Portuguese in Mozambique. Tanzania has both an endoglossic (Swahili) as well as an exoglossic (English) official language.
