|Native to||Equatorial Guinea|
|Region||mainly on Annobón island; some speakers on Bioko island|
The Annobonese language, known to its speakers as Fa d'Ambu, Fa d'Ambö or Fá d'Ambô (Portuguese: Fala de Ano-Bom), is spoken on the Annobon and Bioko Islands off the coast of Equatorial Guinea, mostly by people of mixed African, Spanish, and Portuguese descent.
The 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 of Portuguese and Forro.
Annobonese is analogous to Forro. In fact, it must be derived from Forro as it shares the same structure (82% of its lexicon). After Annobon passed to Spain, the language gained some words of Spanish origin (10% of its lexicon), although it is difficult to be sure, given the similarity between Spanish and Portuguese. Today, the Spanish language is the official language of the island. Portuguese is used as liturgical language. Portuguese is being restored as an official language in Equatorial Guinea.
