Forro or Sãotomense, Santomense, is one of the two creoles languages of the republic of São Tomé and Príncipe, two islands on the west of Gabon. This is exactly the creole of Sao Tomé, the other creole spoken in Principe is the moncó (principense). This portuguese-based creole, counts 90% words of portuguese origin, the others come from the kwas and bantu languages spoken on the continent. Despite this portuguese origin, grammar and deformation of words, do not allow intercomprehension between saotomense and portuguese. The word Forro (sons of the earth), means also the Saotomens people, the speakers of this language. They are a mixed population, of Portuguese settlers and displaced Africans on the island
