Palauan (a tekoi er a Belau) is one of the two official languages of the Republic of Palau, the other being English. It is a member of the Austronesian family of languages, and is one of only two indigenous languages in Micronesia that is not part of the Oceanic branch of that family, the other being Chamorro (see , , , and ). Most researchers agree that Palauan and Chamorro are instead outliers on the Sunda-Sulawesi branch of the Austronesian language family, though it has been claimed that Palauan constitutes a possibly independent branch of the Malayo-Polynesian languages (). The Palauan language is widely used in day-to-day life in Palau.
