The Hispano-Austronesian languages are an informal subdivision of the Austronesian language family, a language family widely dispersed throughout the islands of Southeast Asia and the Pacific, with a few members spoken on continental Asia.
All the Hispano-Austronesian languages belong to the Malayo-Polynesian languages subfamily of the Austronesian language family. All of the languages contained in this subdivision are all alnguages or dialects which have imbibed more than one-third of their vocabulary or grammatical structure from Hispanic languages, particularly Castilian Spanish. All of them, however, are more closely related to the Mexican dialect of the said language.
The Tagalog language, which is the basis of the Philippine national language, Filipino, as well as Chamorro, are the most known members of Hispano-Austronesian. Other Austronesian languages somehow influenced by the Spanish language include Palauan, official language of Palau. and to a lesser degree, Yapese and Chuukese in the Federated States of Micronesia.
"Hispano-Austronesian" is not a clear-cut subdivision of Austronesian, though other scholars have also proposed for the creation of similar groupings, such as "Lusitanian-Austronesian" for Tetum, official language of East Timor, which is heavily influenced by Portuguese, and "Germanic-Austronesian" for some languages in Melanesia, and can be expanded to include institutionalized code-switching and creolizing, such as Taglish in the Philippines, a code-switch language of Tagalog and English, and Tok Pisin, official language of Papua New Guinea. respectively.
