Koro is an Oceanic language spoken on Gaua island in Vanuatu. Its 280 speakers live in the village of Koro, on the south coast of Gaua.
Koro is a distinct language from its immediate neighbours, Dorig (300 sp.) and Olrat (4 sp.).
The name Koro, spelled natively as Kōrō [kʊrʊ], is an endonym referring to the village.
Koro has 8 phonemic vowels. These include 7 monophthongs /i ɪ ɛ a ɔ ʊ u/ and one diphthong /ɛ͡a/.
|Near-close||i ⟨i⟩||u ⟨u⟩|
|Close-mid||ɪ ⟨ē⟩||ʊ ⟨ō⟩|
|Open-mid||ɛ ⟨e⟩||ɔ ⟨o⟩|
The diphthong [ɛ͡a] is spelled as ⟨ä⟩.
The system of personal pronouns in Koro contrasts clusivity, and distinguishes four numbers (singular, dual, trial, plural).
Spatial reference in Koro is based on a system of geocentric (absolute) directionals, which is typical of Oceanic languages.
