Raja Ampat–South Halmahera languages

The Raja Ampat–South Halmahera languages are a branch of Malayo-Polynesian languages of eastern Indonesia. They are spoken on islands in the Halmahera Sea, and on its margins from the south-eastern coast of Halmahera to the Raja Ampat Islands off the western tip of New Guinea.

The languages of the Raja Ampat Islands show a strong Papuan substratum influence; it is not clear that they are actually Austronesian as opposed to relexified Papuan languages.

Remijsen (2001) and Blust (1978) linked the languages of Raja Ampat to the South Halmahera languages.

Languages

From Kamholz (2024). The earlier classification in Kamholz (2014) grouped Ambel and Biga together, but the innovation posited for Proto-Ambel-Biga (innovation of the inalienable possessive plural suffix -n/-no) did not in fact exist:

• Raja Ampat–South Halmahera
• Waigeo (Ambel)
• Biga
• Batta
• Salawati
• As
• Ma'ya-Matbat
• Ma'ya
• Matbat
• South Halmahera (see more)

Laura Arnold (2024) presents a revised classification, placing Biga within Ma'ya and unifying all Raja Ampat languages into a branch with two subgroups, one containing most Raja Ampat languages into a Nuclear Raja Ampat subgroup and the other containing Ambel and As.

• Raja Ampat–South Halmahera
• Raja Ampat
• Ambel-As
• Waigeo (Ambel)
• As
• Nuclear Raja Ampat (= Ma'ya-Matbat)
• Matbat
• Ma'ya-Salawati
• Ma'ya
• Salawati-Batta
• Batta
• Salawati
• South Halmahera (see more)
