When the North Andamanese people were resettled to Strait Island, a koiné developed from the resulting mixture of dialects. It went extinct in the early 2000s.
The remainder of this article concerns the koiné. For more specific information, see the individual dialects.
Great Andamanese koiné is based primarily on Jeru, with lexical and grammatical influence from other Northern Andamanese dialects (Aka-Bo, Aka-Kora and Aka-Cari). It is a head-marking polysynthetic and agglutinative language with a SOV pattern. It has a very elaborate system for marking inalienability, with seven possessive markers reflecting different body-divisions. These markers appear as proclitics that classify a large number of nouns as dependent categories.
