(chä' ) The native Pacific Island people of Guam. Chamorro and English are also the official languages of Guam. Chamorro, as a language, has been evolving for over 5,000 years and belongs to the western group of the Austronesian language family, including the languages of Indonesia, Malaysia, Philippines, and Palau. During its evolution, Spanish and American words have also been incorporated.

The Chamorro family has its origin in Spain. A branch of the family became prominent in Nicaragua in the 18th century and its influence continues to the present. Historically, the Chamorros have been closely associated with the Conservatives, but the Sandinista Revolution has divided their loyalties, with some members supporting the Sandinistas.
