Chamorro Or Chamoru, is the native language of the Northern Mariana Islands and Guam. Although the English language and Japanese language are commonplace on both Guam and the Northern Marianas Islands, people still use the Chamorro language. Chamorro is also used in mainland United States by immigrants and some of their descendants. The numbers of Chamorro speakers have declined in recent years, and the younger generations are less likely to know the language. The influence of English, Spanish, Tagalog, and Japanese have caused the language to become endangered.
