The Do Sono River (Portuguese : Rio do Sono) is a river of Tocantins state in central Brazil. It is a right tributary of the Tocantins River.
Portuguese is a Western Romance language originating in the Iberian Peninsula. It is the sole official language of Portugal, Brazil, Cape Verde, Guinea-Bissau, Mozambique, Angola, and São Tomé and Príncipe. It also has co-official language status in East Timor, Equatorial Guinea and Macau in China. As the result of expansion during colonial times, a cultural presence of Portuguese and Portuguese creole speakers are also found in Goa, Daman and Diu in India; in Batticaloa on the east coast of Sri Lanka; in the Indonesian island of Flores; in the Malacca state of Malaysia; and the ABC islands in the Caribbean where Papiamento is spoken, while Cape Verdean Creole is the most widely spoken Portuguese-based Creole. Reintegrationists maintain that Galician is not a separate language, but a dialect of Portuguese. A Portuguese-speaking person or nation is referred to as "Lusophone" (Lusófono).
Tocantins is one of the states of Brazil.. It is the newest of the 26 Brazilian states, formed in 1988 and encompassing what had formerly been the northern two-fifths of the state of Goiás. Tocantins covers 277,620.91 square kilometres (107,190.03 sq mi) and has a population of 1,496,880. Construction of its capital, Palmas, began in 1989; most of the other cities in the state date to the Portuguese colonial period. With the exception of Araguaína there are few other cities with a significant population in the state. The government has invested in a new capital, a major hydropower dam, railroads and related infrastructure to develop this primarily agricultural area.
Brazil, officially the Federative Republic of Brazil, is the largest country in both South America and Latin America. At 8.5 million square kilometers and with over 208 million people, Brazil is the world's fifth-largest country by area and the fifth most populous. Its capital is Brasília, and its most populated city is São Paulo. The federation is composed of the union of the 26 states, the Federal District, and the 5,570 municipalities. It is the largest country to have Portuguese as an official language and the only one in the Americas; it is also one of the most multicultural and ethnically diverse nations, due to over a century of mass immigration from around the world.
The river has its headwater in the 158,885 hectares (392,610 acres) Jalapão State Park, a fully protected conservation unit created in 2001. [1] It forms where the Novo and Soninho meet on the northwest boundary of the state park.
