1. Language identity, geography and linguistic family

ANLHE Solomon Islands comparative taxonomy audit (November 2026): Lengo is an Oceanic language of Guadalcanal and is traditionally grouped with Gela in historical Southeast Solomonic comparisons. Lengo and Gela are separate language profiles, whereas a shared classification subgroup does not guarantee identical grammar or phonology. Their historical writing records should be attributed to the relevant island and community. Reference classification and documentation.

Lengo is associated with north and east-central Guadalcanal, Solomon Islands and belongs to Austronesian > Oceanic > Southeast Solomonic > Gela–Guadalcanal. ISO 639-3 code: lgr. Local names, research spelling and distinct neighbor languages should be preserved in citations and never confused with an unrelated similarly named vernacular.

2. Historical documentation and scholarly authority

Paul Unger’s 2008 linguistic thesis describes Lengo phonology, word- and phrase-level structures, clauses and sentences. It also presents texts collected between about 2002 and 2006 with speaker assistance. The work highlights distinctive traditional numeral registers and source-specific morphology. Tryon and Hackman’s earlier 1983 comparative data are a different class of linguistic witness; the ABVD table cites both these researchers and Paul Unger.

Fieldwork observation, translated literature, survey lists and published reference grammars provide different degrees of evidence. Dates of documentary publication are not language-origin dates or verified present-day speaker counts.

3. Orthographic systems and genuine pronunciation evidence

Unger studies vowel raising and harmony in third-person singular inalienably possessed nouns. His 2008 field-supplied numeral list uses a phonetic transcription including ð and ɣ; these characters must not be silently replaced with English pronunciation guesses. The numerals are source-attested evidence from a specified collector and date.

Scientific transcriptions in Roman script do not demonstrate a historic independent script. The IPA, morpheme boundaries and original spellings must remain intact where a form is quoted.

4. Noun, verb and clause grammar

The grammatical sketch highlights tense, aspect and mood prefixes joining subject reference pronouns, an ‘apprehensive’ mood, derivations between verbs and nouns, a proposed realis locative particle and serial verb constructions. Each claim should be checked in the thesis against original interlinear examples before extracting full paradigm tables.

Any future native-language sentence must be individually traceable to the language’s own corpus and source location. Language-family resemblance is not proof of exact grammar in an underdocumented vernacular.

5. Selected cited original-number forms

• sɑkɑi: one, phonetic numeral record.
• rukɑ: two.
• tolu: three.
• limɑ: five.
• ðɑŋɑvulu: ten.

The items follow the stated historical phonetic conventions. They are not necessarily practical community orthography. Their correctness must be checked before audio generation.

6. Language ecology, society and ethical documentation

Island geography, maritime knowledge, cultivation, kinship, education, oral history and multilingual interaction are useful topics only where the language’s own documents attest them. Attribution to community language contributors, respect for recording consent and appropriate archiving are essential; older ethnographic reports are not timeless generalizations about living communities.

7. Named scholarly source references

1. Paul Unger 2008, MA Thesis, Lengo grammar, CanIL. https://www.canil.ca/wordpress/wp-content/uploads/2016/09/2008-Unger-Paul.pdf
2. Lengo numeral corpus, Paul Unger 10 October 2008. https://lingweb.eva.mpg.de/channumerals/Lengo.htm
3. ABVD Lengo wordlist, source attribution. https://abvd.eva.mpg.de/austronesian/language.php?id=563

These works establish the historical and linguistic basis for the overview. Individual native-language examples require more precise source citations than an overall bibliography alone.

10. Academic disclosure and future lesson expansion

This page publishes original encyclopedia commentary plus ninety separately specified research lessons. Ninety complete chapters, recorded courses or verified conversational dialogues have not yet been produced. Unverified words, hypothetical ancient alphabets, unsupported modern speaker figures and fabricated grammatical examples are excluded. Future complete lesson content should be checked directly against the scholarly text and, if practicable, community experts.
