A Spanish creole (criollo), or Spanish-based creole language, is a creole language (contact language with native speakers) for which Spanish serves as its substantial lexifier. A number of creole languages are influenced to varying degrees by the Spanish language, including varieties known as Bozal Spanish, Chavacano, and Palenquero. Spanish also influenced other creole languages like Annobonese, Papiamento, and Pichinglis. Any number of Spanish-based pidgins have arisen due to contact between Spanish and other languages, especially in America, such as the used by the Panare people of Venezuela and Roquetas Pidgin Spanish used by agricultural workers in Spain. However, few Spanish pidgins ever creolized with speakers of most pidgins eventually adopting Spanish or other language as their main tongue. Bozal Spanish is a possibly extinct Spanish-based creole language that may have been a mixture of Spanish and Kikongo, with Portuguese influences. Attestation is insufficient to indicate whether Bozal Spanish was ever a single, coherent or stable language, or if the term merely referred to any idiolect of Spanish that included African elements. Bozal Spanish was spoken by African slaves in the Spanish Caribbean and other areas of South and Central America from the 17th century up until its possible extinction at around 1850. It's influenced the variety spoken in the Chota Valley in Ecuador, and a Spanish-based creole is still spoken in the Bolivian Yungas. Chavacano (also Chabacano) is a group of Spanish-based creole language varieties spoken in the Philippines that emerged during the 18th century following the colonization of the Spaniards in the Philippines. While Chavacano refers to a large number of varieties, there are three main varieties: Ternate, Manila/Cavite, and Zamboanga.Ternate and Manila/Cavite are Northern dialects from Manila Bay on Luzon Island, while Zamboanga is a Southern dialect from Mindanao Island; both of these dialects are genetically related.
