Proto-Oceanic (abbreviated asPOc) is aproto-language thathistorical linguists sinceOtto Dempwolff have reconstructed as the hypothetical common ancestor of theOceanic subgroup of theAustronesian language family. Proto-Oceanic is a descendant of theProto-Austronesian language (PAN), the common ancestor of the Austronesian languages.

Proto-Oceanic was probably spoken around the late 2nd millennium BCE in theBismarck Archipelago, east ofPapua New Guinea.^[1] Archaeologists and linguists currently agree that its community more or less coincides with theLapita culture.

The methodology ofcomparative linguistics, together with the relative homogeneity ofOceanic languages, make it possible to reconstruct with reasonable certainty the principal linguistic properties of their common ancestor, Proto-Oceanic. Like all scientific hypotheses, these reconstructions must be understood as obviously reflecting the state of science at a particular moment in time; the detail of these reconstructions is still the object of much discussion amongOceanicist scholars.

The phonology of POc can be reconstructed with reasonable certainty.^[2]Proto-Oceanic had five vowels: *i, *e, *a, *o, *u, with no length contrast.

Twenty-three consonants are reconstructed. When the conventional transcription of a protophoneme differs from its value in theIPA, the latter is indicated:

Based on evidence from theSouthern Oceanic andMicronesian languages,Lynch (2003) proposes that the bilabial series may have been phonetically realized aspalatalized:/pʲ//ᵐbʲ//mʲ/.^[4]

Many Oceanic languages ofNew Guinea,Vanuatu, theSolomon Islands, andMicronesia areSVO, or verb-medial, languages.SOV, or verb-final, word order is considered to be typologically unusual for Austronesian languages, and is only found in some Oceanic languages of New Guinea and to a more limited extent, the Solomon Islands. This is because SOV word order is very common in some non-AustronesianPapuan languages in contact with Oceanic languages. In turn, mostPolynesian languages, and several languages ofNew Caledonia, have theVSO word order. Whether Proto-Oceanic had SVO or VSO is still debatable.

From the mid-1990s to 2023, reconstructing thelexicon of Proto-Oceanic was the object of theOceanic Lexicon Project, run by scholarsAndrew Pawley,Malcolm Ross and Meredith Osmond.^[5] This encyclopedic project produced 6 volumes altogether, allavailable in open access.

In addition,Robert Blust also includes Proto-Oceanic in hisAustronesian Comparative Dictionary (abbr. ACD).^[6]
