"Timor" derives from timur, the word for "east" in Malay, which became recorded as Timor in Portuguese, thus resulting in the tautological toponym meaning "East East": In Portuguese Timor-Leste (Leste being the word for "east"); in Tetum Timór Lorosa'e (Lorosa'e being the word for "east" (lit "rising sun")).
The official names under the Constitution are Democratic Republic of Timor-Leste[REF] in English, República Democrática de Timor-Leste[REF] in Portuguese and Repúblika Demokrátika Timór-Leste[REF] in Tetum.
