SHI recently commented that linguistic genocide was also occurring in India, Indonesia, and Thailand as Hindi, Bahasa Indonesia, and Thai take out the many other languages spoken in those lands.
They speak of a Hindi dialect continuum with maybe 200-300 languages in it. I am wondering what the mutual intelligibility figures are for that continuum?
Yes, Bahasa Indonesia is taking out those other languages. Also, I am not sure that those other languages are offered as native language instruction in the schools. Though I recently talked for a few years with a teenage girl from Jogjakarta who spoke Javanese as a native language. She said everyone around her did too.
Thai is taking out the other languages of Spain. But Isan does have 18 million speakers. It’s the native language of the Thais who live in Northeastern Thailand. I corresponded with a Thai woman for several years who was a native Isan speaker. It’s just about mutually intelligible with Lao. Thais claim that Lao and Isan are mutually intelligible with Thai, but if you look at a word list, you can’t see how that’s the case.
In Southern Thailand, Southern Thai has three million speakers is still doing well. A form of Malay is still widely spoken in the Muslim South.
