Swahili
Swahili is Tanzania’s constitutionally designated national language, used widely in government, primary schools, mass media and everyday life. Adopted after independence to unify diverse ethnic groups, it serves as the primary lingua franca across mainland Tanzania and Zanzibar.

English
English remains the main language of higher courts, universities and many formal government functions, a carryover from British colonial rule. While not named as national language in the constitution, English is widely used in law, tertiary education and professional sectors.
