Chamorro language
Malayo-Polynesian (Austronesian) language, spoken on the Mariana Islands

Chamorro is an Austronesian language spoken by about 58,000 people, numbering about 25,800 on Guam and about 32,200 in the Northern Mariana Islands and elsewhere.
It is the historic native language of the Chamorro people, who are indigenous to the Mariana Islands, although it is less commonly spoken today than in the past. Chamorro has three distinct dialects: Guamanian, Rotanese, and that in the other Northern Mariana Islands (NMI).
Classification
Unlike most of its neighbors, Chamorro is not classified as a Micronesian or Polynesian language. Rather, like Palauan, it possibly constitutes an independent branch of the Malayo-Polynesian language family.
At the time the Spanish rule over Guam ended, it was thought that Chamorro was a semi-creole language, with a substantial amount of the vocabulary of Spanish origin and beginning to have a high level of mutual intelligibility with Spanish. It is reported that even in the early 1920s, Spanish was reported to be a living language in Guam for commercial transactions, but the use of Spanish and Chamorro was rapidly declining as a result of English pressure.
Spanish influences in Chamorro exist due to three centuries of Spanish colonial rule. Many words in the Chamorro lexicon are of Latin etymological origin via Spanish, but the pronunciation of these loanwords has been nativized to the phonology of Chamorro, and their use conforms to indigenous grammatical structures. Some authors consider Chamorro a mixed language under a historical point of view, even though it remains independent and unique.
This brief starts where responsible research should: with the source description of “Chamorro language” as malayo-Polynesian (Austronesian) language, spoken on the Mariana Islands. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as malayo-Polynesian (Austronesian) language, spoken on the Mariana Islands. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 10, 2026. The linked authority identifier is Q33262. Authority coordinates are 16.705, 145.780. None of the 1 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
