1. Community and documentary identity

ANLHE Solomon Islands linguistic identity audit (November 2026): Blablanga (Blanga) is documented around the Maringe district of Santa Isabel. It belongs among Northwest Solomonic Oceanic languages and is distinct from the neighboring Cheke Holo, Kokota and Zabana varieties. Its alternative names and colonial geographical labels must not be counted as separate language identities without independent supporting evidence. Language inventory and classification reference.

Blablanga (Blanga) is associated with Santa Isabel Island, Solomon Islands. ISO 639-3: blp. The language’s history must be distinguished from scholarly documentation dates. Radu Voica assembled annotated audio-video documentation and completed a 2017 SOAS thesis, A Fieldwork-Based Approach to Blanga (Blablanga), focusing on predicate–argument relations. His 2011 paper described verbal agreement. A 2003-initiated ELDP project set out community-led literacy resources, a trilingual Blablanga–English–Pijin dictionary and a grammar. Proposed work and completed outputs should not be conflated, and dated speaker estimates in project records differ.

2. Orthography, phonology and source fidelity

Voica’s thesis examines vocalic segments, vowel length, laryngealization and word-final vowel deletion. These source-specific phonetic processes should be distinguished from the proposed practical orthography and verified in annotated original recordings.

3. Grammar and original source analysis

Predicate–argument relations and agreement have dedicated documentary study. Their analysis should cite the full context of a transcribed clause; no universally valid paradigm should be inferred from the title of a paper alone.

4. Lexical evidence and metadata

The forms below are limited source-attested examples or explicitly labeled catalog metadata; they are not a complete native-language phrasebook.

• blp: ISO code, not a vernacular form
• Blanga: short name used by the scholarly dissertation

Never generate unattested sentences by recombining headwords.

5. Social and cultural interpretation

undefined Historic fieldwork is not a current demographic census, and attributed narratives may require permission for reproduction.

9. Editorial boundaries

This is a documented encyclopedia profile with ninety distinct research objectives. No unsupported quotation, imaginary ancient alphabet, invented local phrase or unverified speaker count is certified as fact. Finished language lessons require direct source checking and, where possible, community review.
