The South Halmahera–West New Guinea (SHWNG) languages are a branch of the Malayo-Polynesian languages, found in the islands and along the shores of the Halmahera Sea in the Indonesian province of North Maluku and of Cenderawasih Bay in the provinces of Papua and West Papua. There are 38 languages.
The unity of the South Halmahera–West New Guinea subgroup is well supported by lexical and phonological evidence. Blust (1978) has proposed that they are most closely related to the Oceanic languages, but this classification is not universally accepted.Blust, R. (1978). "Eastern Malayo-Polynesian: A Subgrouping Argument". In Wurm, S.A. & Carrington, L. (eds.) Second International Conference on Austronesian Linguistics: Proceedings, pp. 181-234. Canberra: Australian National University. (Pacific Linguistics C-61).
Most of the languages are only known from short word lists, but Buli, Patani and Taba on Halmahera, Ambel on Raja Ampat, and Biak, Wamesa, Wooi, and Waropen in Cenderawasih Bay, are fairly well attested.
Classification Traditionally, the languages are classified into two geographic groups: South Halmahera languages (along the southeastern coast of Halmahera, plus one language in the east of the Bomberai Peninsula). West New Guinea languages (on the Raja Ampat Islands west of New Guinea, and the islands and shoreline of Cenderawasih Bay).
The unity of the South Halmahera and Raja Ampat languages is supported by phonological changes noted in Blust (1978) and Remijsen (2002). This results in the following structure: Cenderawasih Bay Raja Ampat–South Halmahera (RASH) (South Halmahera, in the sea between Halmahera and New Guinea, and Raja Ampat off the western tip of New Guinea)
David Kamholz (2014) includes these languages as additional branches: Lower Mamberamo (sometimes also considered to be Papuan, and may be of mixed Austronesian and Papuan origin) Mor Tandia Waropen
The following language groups are problematic – they may or may not be SHWNG. Kamholz (2014) does not classify them due to lack of data. Grimes & Edwards include them with the Kei–Tanimbar languages, and Kamholz (2024) does not list them as part of SHWNG.Charles Grimes & Owen Edwards (in process) Wallacean subgroups: unravelling the prehistory and classification of the Austronesian languages of eastern Indonesia and Timor-Leste. Summary presentation at the 15th International Conference on Austronesian Linguistics. Irarutu–Nabi: Irarutu, Kuri (Nabi) Bedoanas–Erokwanas: Arguni, Bedoanas, Erokwanas
Although the Kowiai language is considered part of SHWNG in Blust's Austronesian Comparative Dictionary, it is not listed as such by Kamholz (2024). Grimes & Edwards include Kowiai within the Seram Laut group. Kowiai
Kamholz (2014, 2024) The SHWNG languages can be categorized as follows (Kamholz 2014: 136-141, Kamholz 2024: 183):Kamholz, David (2014).

Kamholz (2014) presumes the homeland of proto-SHWNG to be the southern coast of the Cenderawasih Bay, around 3,500 years ago.
Kamholz (2024) revises the tree shown above, separating Ambel-Biga into two primary branches of RASH.
Typology At least six SHWNG languages, namely Ma'ya, Matbat, Ambel, Moor, Yaur, and Yerisiam, are tonal.Kamholz, David. 2017. Tone and language contact in southern Cenderawasih Bay. NUSA: Linguistic studies of languages in and around Indonesia, no.62, p.7-39. Klamer, et al. (2008) suggest that tone in these SHWNG languages originated from contact with Papuan languages of the Raja Ampat Islands that are now extinct. There are few lexical similarities with present-day Papuan languages, except for a few words such as 'sago' that are shared with the two tonal Papuan isolates Abun and Mpur (both spoken on the north coast of the Bird's Head Peninsula):Klamer, Marian; Ger Reesink; and Miriam van Staden. 2008. East Nusantara as a Linguistic Area. In Pieter Muysken (ed.), From linguistic areas to areal linguistics, 95-149. Amsterdam: John Benjamins.
biH (Ma'ya) bei (Abun) biL (Mpur)
However, Arnold (2018) traces this etymology to Proto-Malayo-Polynesian *Rambia 'sago palm'.
Arnold (2018) reconstructs tone for Proto-Ma'ya-Matbat and Proto-Ambel, but not for Proto-SHWNG. Other than tonogenesis, these proto-languages had also gone through monosyllabization through apocope.Arnold, Laura. 2018. 'A preliminary archaeology of tone in Raja Ampat'. In Antoinette Schapper, ed. Contact and substrate in the languages of Wallacea, Part 2. NUSA 64: 7–37.
The VRK Mutation is characteristic of most SHWNG languages (except for the RASH languages), where the phonemes , , and surface as the prenasalized voiced stops , , and in various cluster environments.Gasser, Emily. 2018. Surprising Phonology: Typology and Diachrony of Austronesian VRK Mutation. Talk presented at Yale University. The mutation is found in the Ambai, Ansus, Biak, Busami, Dusner, Kurudu, Marau, Meoswar, Moor, Munggui, Papuma, Pom, Roon, Roswar (possibly equivalent to Meoswar), Serewen (possibly a dialect of Pom), Serui-Laut, Umar, Wamesa, Warembori, Waropen, Wooi, Yaur, Yerisiam, and Yoke languages.Gasser, Emily. 2018.

Paper presented at the 14th International Conference on Austronesian Linguistics (14ICAL), Université d'Antananarivo, Madagascar, July 17-20. (Slides)
Kamholz notes that SHWNG languages have relatively low lexical retention rates from Proto-Malayo-Polynesian, pointing to significant influence from non-Austronesian Papuan languages.
