Chavacano is a Spanish-based creole language and known in linguistics as Philippine Creole Spanish. Spaniards who settled in the Philippines intermingled with the natives and even married Filipinas. To be able to communicate, both sides had to learn each other’s languages. To express themselves, the natives mixed Spanish with their particular language — Tagalog in Cavite, Ternate, and Manila; and Cebuano, Hiligaynon, and Moro languages in Cotabato, Davao, and Zamboanga. As such, there are six varieties of Chavacano: Caviteño, Cotabateño, Davaoeño, Ermiteño, Ternateño, and Zamboangueño.
The Davaoeño Chavacanos are found in Davao Oriental, Davao del Sur, and some areas of Davao City. There were around 59,000 speakers of Davaoeño in 2000.
