Indosphere


Indosphere is a term coined by the linguist James Matisoff for areas of Indian linguistic and cultural influence in Southeast Asia. It is commonly used in areal linguistics in contrast with Sinosphere.

The Tibeto-Burman family of languages, which extends over a huge geographic range, is characterized by great typological diversity, comprising languages that range from the highly tonal, monosyllabic, analytic type with practically no affixational morphology, like the Loloish languages, to marginally tonal or atonal languages with complex systems of verbal agreement morphology, like the Kiranti group of Nepal. This diversity is partly to be explained in terms of areal influences from Chinese on the one hand and Indo-Aryan languages on the other. Matisoff proposed two large and overlapping areas combining cultural and linguistic features – the "Sinosphere" and the "Indosphere", influenced by China and India respectively. A buffer zone between them as a third group was proposed by Kristine A. Hildebrandt, followed by B. Bickel and J. Nichols. The Indosphere is dominated by Indic languages.

Some languages and cultures firmly belong to one or the other. For example, the Munda and Khasi branches of Austroasiatic languages, the Tibeto-Burman languages of Eastern Nepal, and much of the "Kamarupan" group of Tibeto-Burman, which most notably includes the Meitei (Manipuri), are Indospheric; while the Hmong–Mien family, the Kam–Sui branch of Kadai, the Loloish branch of Tibeto-Burman, and Vietnamese (Viet–Muong) are Sinospheric. Some other languages, like Thai and Tibetan, have been influenced by both Chinese and Indian culture at different historical periods. Still other linguistic communities are so remote geographically that they have escaped significant influence from either. For example, the Aslian branch of Mon–Khmer in Malaya, or the Nicobarese branch of Mon–Khmer in the Nicobar Islands of the Indian Ocean show little influence by Sinosphere or Indosphere. The Bodish languages and Kham languages are characterized by hybrid prosodic properties akin to related Indospheric languages towards the west and also Sinospheric languages towards the east. Some languages of the Kiranti group in the Indosphere rank among the morphologically most complex languages of Asia.
