Indo-Aryan languages, grouping according to SIL Ethnologue: Central and East Central zones Northern zone Northwestern zone Eastern zone Southern zone Insular
(The relation of this family to other Indo-Aryan languages is unclear; but SIL includes it in the Northwestern zone anyways, despite these languages having a very different grammatical structure from classic Indo-Aryan Languages.)
The insular languages are spoken on the islands of Sri Lanka, Minicoy and the Maldives. They share several characteristics which set them apart significantly from their continental sister languages. (SIL makes them a separate branch of Indo-Aryan.)
