Guinea-Bissau Creole  Guinea-Bissau Creole, also known as Kiriol, is a creole language whose lexicon derives mostly from Portuguese. It is spoken in Guinea Bissau, Senegal and The Gambia. It is also called by its native speakers as "guinensi", "kriyol", or . Guinea-Bissau Creole is spoken as a native tongue by approximately 15% (190,000) of Bissau-Guineans and as a second language by approximately 50% (as of some time before 1992). A variant of Guinea-Bissau Creole is also spoken in southern Senegal, mainly in the region of Casamance, a former Portuguese colony, which is known as Portuguis Creole or Casamance Creole. Creole is the majority language of the inhabitants of the Casamance region and is used as a language of commerce. Standard Portuguese is the official language of Guinea-Bissau, but Guinea-Bissau Creole is the language of trade, informal literature and entertainment. It is not used in either news media, parliament, public services or educational programming. The creole languages of Upper Guinea are the oldest-known creoles whose lexicons derive heavily from Portuguese. They first appeared around Portuguese settlements established along the northwest coast of Africa; Guinea-Bissau Creole was among these Portuguese-lexified creoles to have emerged. Portuguese merchants and settlers started to mix with locals almost immediately. A small body of settlers called "lançados" ("the thrown out ones"), contributed to the spread of the Portuguese language and influence by being intermediaries between the Portuguese and natives. There are three main varieties of this creole in Guinea-Bissau and Senegal: Bissau and Bolama, Bafata, and Cacheu–Ziguinchor. The creole's substrate language is the language of the local peoples: Mandingas, Manjacos, Pepéis and others, but most of the lexicon (around 80%) comes from Portuguese. The Portuguese-influenced dialect of Casamance, known as Portuguis Creole or Casamance Creole, similar to the one of Cacheu (Guinea-Bissau) has some influence of French. ' (, English: Children of the Land) and ' (Port. "", Eng. Children of Nobles) speak it, all of them are known, locally, as Purtuguis because they adopt European habits, are Catholics and speak a Creole.
