Proto-Polynesian language
hypothetical proto-language from which modern Polynesian languages descend, a daughter language of the Proto-Austronesian
Proto-Polynesian (abbreviated PPn) is the reconstructed proto-language from which all modern Polynesian languages descend. It is a descendant of the Proto-Oceanic language (the language associated with the Lapita civilization), itself a descendant of Proto-Austronesian. The homeland of Proto-Polynesian speakers is believed to have been Tonga, Samoa, and nearby islands.
Phonology
Proto-Polynesian has a small phonological inventory, with 13 consonants and 5 vowels.
Consonants
Vowels
Proto-Polynesian had five vowels, /a/ /e/ /i/ /o/ /u/, with no length distinction. In a number of daughter languages, successive sequences of vowels came together to produce long vowels and diphthongs, and in some languages these sounds later became phonemic.
Sound correspondences
Following principles of the Comparative method, it is possible to observe regular sound correspondences among Polynesian languages, and to reconstruct the most likely protophoneme for every ancestral step.
Vocabulary
The following is a table of some sample vocabulary as it is represented orthographically in various languages. All instances of ⟨ʻ⟩ represent a glottal stop, IPA /ʔ/. All instances of ⟨ng⟩ and Samoan ⟨g⟩ represent the single phoneme /ŋ/.
This brief starts where responsible research should: with the source description of “Proto-Polynesian language” as hypothetical proto-language from which modern Polynesian languages descend, a daughter language of the Proto-Austronesian. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as hypothetical proto-language from which modern Polynesian languages descend, a daughter language of the Proto-Austronesian. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 22, 2026. The linked authority identifier is Q1658709. The Library of Congress control number is sh85107761. None of the 1 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
