Summer Institute of Linguistics (eds.). Languages of the Southern Gateway: A Phrase Book of Chavacano, Sinama, Tausug, Yakan, and Including English and Pilipino

Summer Institute of Linguistics, 1979. — 117 p.Not formally an 'about' book but it does touch on the history of certain Mindanao dialects, with Tagalog and English translations. Chavacano or Chabacano is a group of Spanish-based creole language varieties spoken in the Philippines. The variety spoken in Zamboanga City, located in the southern Philippine island group of Mindanao, has the highest concentration of speakers. Other currently existing varieties are found in Cavite City and Ternate, located in the Cavite province on the island of Luzon. The different varieties of Chavacano differ in certain aspects like vocabulary but they are generally mutually intelligible by speakers of these varieties, especially between neighboring varieties. While a majority of the lexicon of the different Chavacano varieties derive from Spanish, their grammatical structures are generally similar to other Philippine languages. Among Philippine languages, it is the only one that is not an Austronesian language, but like Malayo-Polynesian languages, it uses reduplication.
