How did Spanish contact influence the Chamorro language?

The Chamorro language underwent significant transformation due to more than four centuries of Western contact, particularly following the arrival of the Spanish in the 17th century.12

As a result of this prolonged interaction, the language incorporated a substantial number of Spanish words into its vocabulary. In addition to this direct Spanish influence, the language is also believed to have been shaped by the Tagalog language of the Philippines, which served as a major hub for Spanish colonial administration in the Pacific.132

Despite these external influences, Chamorro remains a distinct Austronesian language with its own unique grammar and vocabulary, rather than a Micronesian dialect. Today, it continues to be spoken in many homes on Guam, even as English serves as the official language for education and commerce.413
