1. Linguistic classification and geography

ANLHE Micronesia and New Ireland taxonomy audit (November 2026): Pááfang, associated with Murilo and Fananu, is a Micronesian Oceanic member of the Satawalese–Carolinian cluster. It is closely related to but distinct in reference catalogues from Namonuito and Satawalese. The spelling of a language name, the originating island and the broader Chuukic subgroup are three separate types of metadata. Source for comparative classification.

Pááfang (Murilo-Fananu) is associated with Hall Islands of Fananu, Murilo, Nomwin and Ruo in Chuuk State, Federated States of Micronesia. Its documented classification is Austronesian → Oceanic → Micronesian → Chuukic. Local community names should take precedence over broad regional labels. A scholarly classification or published date does not show when the language began.

2. Language history and source criticism

Pááfang, also written Pááféng, is separately coded ISO 639-3 pfa and Glottocode paaf1237. Edward Quackenbush’s 1968 comparative survey lists a Murilo sample in his Sonsorol-to-Truk dialect chain. Emerson Odango collected and published a Pááfang numeral and phonetic study in 2011, providing more specific data on counting with classifiers. The original survey’s local labels must not be equated with a full modern census or uniform usage in every village.

Field notebooks, language-catalogue classifications and current community practices are different kinds of evidence and must be separately attributed. No unverified contemporary population number is inferred from a historical survey.

3. Script, alphabet, phonetic and phonological evidence

Odango’s phonetic chart records a range of vowels and consonants and requires careful distinction between phonetic symbols and ordinary writing. The author gives variant names Pááféng and Pááfang; these should be catalogued faithfully rather than treated as separate languages. Secondary reference orthographies expressly acknowledge uncertainty, so unverified spelling rules are not appropriate for a course.

When a source uses the IPA, accent marks or a special transcription convention, preserve its spelling and explanatory notes. A modern Roman-script transcription is not evidence for a previously existing ancient script.

4. Grammar and language-specific interpretation

The 2011 source describes a decimal numeral system and several classifiers associated with different nouns, comparable in broad function to those in Mortlockese. Students can analyze classifier selection and lexical categories using the authentic numerals table, but must not improvise a full grammatical description from these data alone.

Do not copy examples from Chuukese, Yapese, Ulithian or any other neighboring language. If no descriptive corpus confirms a grammatical paradigm, the corresponding topic remains a documented research objective rather than a finished lesson explanation.

5. Verified examples and explicitly identified metadata

Small original-language examples are presented only where the cited materials support them. Codes and proper names are identified explicitly so that catalogue metadata cannot be mistaken for vocabulary.

• pworausen Pááféng: autonym in language metadata.
• pfa: ISO 639-3 identifier, not a native vocabulary word.
• paaf1237: Glottocode, not a spoken form.

6. Social and cultural knowledge in context

Maritime travel, island ecology, household life, migration and contact with neighboring communities may help interpret archival vocabulary and oral traditions. These historical themes require community testimony and should never be attributed wholesale to present-day speakers without evidence. Community rights and permissions are relevant to publishing fuller texts.

7. Bibliographic and archival witness list

• Emerson Odango (2011), Pááfang numerals and phonetics, Max Planck numerals archive. https://lingweb.eva.mpg.de/channumerals/Paafang.htm
• Quackenbush (1968), From Sonsorol to Truk: A Dialect Chain. https://glottolog.org/resource/reference/id/123099
• Pááfang language metadata, Dialect and related language archive. https://arc.dbs.org/data/languages/pfa/

Source listings enable readers to verify specific statements. A whole book citation does not authenticate an invented dialogue, and future lesson expansions should attach the exact page, entry or recording identifier.

8. Ninety separately named documentary research lessons

The curriculum uses nine modules of ten evidence-led topics and is suitable for gradual expansion into fully documented educational materials. In a source-poor language, some lessons teach methods for investigating unanswered questions rather than asserting facts not present in the archives.

9. Academic editorial declaration

This profile contains historical and linguistic analysis and a curriculum of ninety research objectives. It does not claim the existence of ninety completed audiovisual lessons or full native-language dialogues. Any subsequent detailed lesson must be checked for source accuracy, language identification, original orthography, community attribution, and quotation or reproduction rights before publication.
