The Annobonese is a Portuguese creole known to its speakers as Fa d'Ambu or Fá d'Ambô (Portuguese: Fala de Ano-Bom), It is spoken on the Annobon and Bioko Islands off the coast of Equatorial Guinea, mostly by people of mixed African, Portuguese and Spanish descent. It is called annobonense or annobonés in Spanish.
The attitude in the country towards this language is positive. It is taught in special courses in the capital of Equatorial Guinea, Malabo.
The creole language was spoken originally by the descendants of intermixing between Portuguese men and African women slaves imported from other places, especially from São Tomé and Angola, and therefore descends from Portuguese and Forro, the creole of the freed slaves of São Tomé. The government of Equatorial Guinea financed an Instituto Internacional da Língua Portuguesa (IILP) sociolinguistic study in Annobon, which noticed strong links with the Portuguese creole populations in São Tomé and Príncipe, Cape Verde and Guinea-Bissau.
Annobonese is analogous to Forro. In fact, it must be derived from Forro as it shares the same structure and 82% of its lexicon. After Annobon passed to Spain, the language incorporated some words of Spanish origin (10% of its lexicon),, but it is often difficult to say from which language the word derive, given the similarity between Spanish and Portuguese. Today, the Spanish language is the official language of the island, although it is not much spoken and the Portuguese creole has vigorous use in the island and in the capital Malabo and with some speakers in Equatorial Guinea's mainland. Noncreolized Portuguese is used as liturgical language. Portuguese has been declared an official language in Equatorial Guinea, but so far is rarely used in Bioko and Rio Muñi.
