1. Identity, geographic history and classification

Editorial classification note (November 2026): Olrat has the ISO 639-3 code [olr], but Glottolog classifies Olrat as a dialect within the Koro–Olrat language [krf], noting mutual intelligibility. Separate profiles preserve community and documentary distinctions; they must not be automatically counted as two independent languages in every classification. See Glottolog: Olrat and Glottolog: Koro–Olrat.

Olrat (Viar) is historically associated with Jōlap and west coast of Gaua, Banks Islands, Vanuatu. Source identifier: olr. Olrat, with Viar described as an associated variety, has an ISO 639-3 identifier, but classification is contested: Glottolog treats Olrat as a dialect associated with Koro, citing mutual intelligibility. Historical François research also lists it among locally named indigenous Gaua languages. This profile preserves both catalogue treatments and does not pretend consensus on language versus dialect boundaries.

The language’s identity should not be deduced solely from a catalogue label, and documented linguistic varieties must not be conflated with others without analytical support.

2. Documentary timeline, source reliability and vitality

Alexandre François recorded Olrat numerals on 10 May 2006. The Max Planck corpus reported three remaining speakers in its original historical note and identifies the language as endangered. That figure is from 2006, not an independently verified count in 2026. Comparative studies show that Olrat, Dorig and Lakon were historically used in the same village of Jōlap; multilingualism and historical transmission should be treated as source-dated observations.

Source dates, fieldwork sample sizes, reported vitality status and later community circumstances are different categories. Historical estimates must remain explicitly dated rather than promoted to current statistics.

3. Alphabet, phonetics and original-source orthography

The numeral archive contains phonetic β, ɣ, ɛ and ʊ; these symbols reflect the linguist’s transcription. Source readings should preserve them, without substituting Lakon spelling or assuming the IPA table is the current community orthography.

Source IPA, community spelling and inherited phonological reconstructions should be separated. There is no reason to invent an ancient alphabet from present-day romanization.

4. Verifiable grammatical and lexical structures

Olrat exhibits a five-derived system for six to nine, e.g. lɛβɛtɛ for six, and decimal formations such as ɣapra for ten. The source documents a particular numerical subsystem, not complete pronominal or verbal grammar. The Gaua directional system comparative paper helps frame geography, but individual Olrat lexical forms must be validated separately.

The academic curriculum prioritizes source-based clause or headword examples. Where no complete reference grammar exists, grammar lessons ask specific documentary questions rather than assert unsupported paradigms.

5. Limited authentic original-language forms and catalogue labels

These forms retain the stated archival conventions. Entries that are codes, names or source annotation labels are not presented as ordinary conversation.

• tuwa: one (2006 phonetic record)
• ni-rʊ: two
• ni-tɪl: three
• taβalɪm: five
• lɛβɛtɛ: six
• ɣapra: ten

6. Culture, narrative and community rights

Historical island settlement patterns, navigation, ecological knowledge, kinship and oral narratives inform documentary research. Statements about present-day usage must be separately verified. Research should acknowledge narrators and preserve community control over permissions and cultural representations.

10. Academic integrity and completion status

This is an original source-informed encyclopedia article containing ninety separately named documentary research objectives. It does not claim ninety completed bilingual textbooks or audio lessons. Unattested native sentences, fabricated scripts, unsupported speaker numbers and hidden language-versus-dialect uncertainties are excluded. Full expansion requires exact primary citations and responsible community and archive review.
