Timor-Leste's languages belong mainly to Austronesian and Papuan language families. Tétum Prasa, also called Tetun Prasa, functions as the nationwide lingua franca. Tétum Oficial is based on Tétum Prasa and is used in general education, official publications and media. Tetun Terik is a distinct regional variety. The Constitution recognizes Tétum and Português as official languages and requires the state to value and develop Tétum and other national languages. The country has at least 16 local languages and varieties, including Mambai, Makasae, Baikenu, Kemak, Bunak, Tokodede, Fataluku, Waima'a, Naueti, Galoli, Midiki, Idate, Makalero, Kairui-Kawaimina, Bekais, Habun, Lakalei, Lolein, Makuva, Sa'ani, Dadu'a, Atauran, Rahesuk, Raklungu, Resuk, Nanaek and Adabe. Mambai is especially common in the central and southern highlands; Makasae in Baucau and Viqueque; Fataluku in Lautém; Baikenu in Oe-Cusse; Galoli in Manatuto; and Tokodede in Liquiçá. Language boundaries often overlap, and many communities use more than one language. The 2015 census recorded about 361,027 people with Tétum Prasa as their mother tongue and about 571,406 using it as a second language. Mambai, Makasae, Tetun Terik, Baikenu, Kemak, Bunak, Tokodede and Fataluku were among the largest other mother-tongue groups. Português has strong legal and institutional use but less equal reach in everyday life. Indonesian and English are working languages in the civil service under Constitutional Article 159 only while required; they do not have the same status as official languages. Court documents may be in Tétum or Português, and foreign-language documents may require translation. Public signs should prioritize Tétum Oficial and Português, with Indonesian or English appearing only alongside visibly primary Tétum or Português text. The education law adopted in 2026 designates Tétum and Português as teaching languages. Mother-tongue support remains a tool for learning, cognitive development and inclusion. EMULI is an early-learning approach that begins in the home language and transitions toward Tétum and Português; its continuation was announced in 62 schools, with around 50 additional applications. Pilot languages include Fataluku, Galolen and Baikeno. RTTL broadcasts mainly in Tétum and Português, while local languages are used especially in community and cultural programming. Parliament, the Government, the Ministry of Education, INL and UNTL, INETL, the Ministry of Justice, the Secretariat of State for Social Communication, RTTL and municipal authorities each have roles in language policy or implementation. Tétum provides the widest general access, but a lack of local-language support can still limit participation in rural areas. No general right to administration in every national language, nationwide fee or uniform processing time is established; translation and interpreting depend on the institution and procedure.
Language in Timor-Leste
Timor-Leste has two official languages, Tétum and Português, while Indonesian and English may serve as working languages in public service when needed. Tétum Prasa is the country's broadest common language and the basis of the official Tétum standard. At least 16 national languages and varieties remain central to regional identity, family life, culture and early education. Language choice affects access to government, courts, schools, media and public participation.
Tip
Use Tétum for the widest everyday reach, add Português when legal or institutional wording is involved, and use a relevant local language when regional access or early learning requires it. Treat Indonesian and English as supporting languages for specific administrative or international situations, not as replacements for the two official languages. Check language support with the responsible institution instead of assuming that every service is available in every national language.
