This paper reviews the historical and sociolinguistic evolution of Fa d’Ambô, a Portuguese-linked creole language spoken initially on the small Annobón island in Equatorial Guinea. Fa d’Ambô and the three creole languages spoken on the islands of São Tomé and Príncipe derive from a unique contact language that emerged on the island of São Tomé and ramified in the 16th century. After its lasting settlement in the second half of the 16th century, Annobón became strongly secluded until the 20th century. Given intensive migration from Annobón to Equatorial Guinea’s multilingual capital Malabo during the last decades, Fa d’Ambô’s speech community has split and became more exposed to other languages, especially English-based creole Pichi, the capital’s lingua franca. Given the speech community's small size (approx. 5,000 speakers), and absence of government help for the country’s minority languages, the survival of the language is threatened.
