Sonsorolese is a Micronesian language spoken in Palau, originally on the islands composing the state of Sonsorol, and spreading through migration elsewhere in the country.

Sonsorolese is mostly spoken in the Palau archipelago, particularly in Sonsorol, Pulo Ana, and the Merir Islands.

[4] Some closely related languages of Sonsorol are Ulithian, Woleaian, and Satawalese.

Most of the population have migrated from the islands of the Sonsorol state to Palau's main town, Koror and Echang village.

A couple of dialects include the pronunciation of d, which is common at the beginning of words and similar to [ð]; r is pronounced as in Spanish; also, l is always pronounced with tongue touching the back roof of the mouth and sounds something like a combination of the [ɡ] and [l] sounds.

[4] Written documents in Sonsorolese include the Constitution of Sonsorol State and certain parts of the Bible.
