Sula language
Sula is a Malayo-Polynesian language of the Central Maluku branch. It is related to the Buru language.

It is definitely endangered, currently under pressure from the local variety of Malay.<p>
Sula has borrowed many lexical items from Ambonese Malay, as well as Ternate, a more dominant language of North Maluku. Dutch loans have entered the language too, perhaps through Malay and Ternate. Standard Indonesian has also been influential.<p>

Mangole is sometimes listed as a distinct language.
