Question

When was the austro-asiatic language family proposed?

Answer 1

Austroasiatic languages.
The Austroasiatic languages, formerly known as Mon–Khmer, are a large language family of Mainland Southeast Asia, also scattered throughout India, Bangladesh, Nepal and the southern border of China, with around 117 million speakers

language family consists of 169 languages spoken in Southeast Asia, in countries located between China and Indonesia. A few are spoken to the west of this area in the Nicobar Islands and in India. The austro– part of the name comes from the Latin word for ‘south.’

It is not known where the speakers of Austro-Asiatic languages came from or when they migrated to this part of the world. It is generally conjectured that they originated in southern or southeastern China some time between 2,000-2,500 BC, and migrated south into the Indo-Chinese peninsula and west into India. Invasions by speakers of other languages split the Austro-Asiatic languages into several groups. The date of separation of the two main Austroasiatic subfamilies—Mon-Khmer and Munda—has never been definitively established and must have occurred in prehistoric times.
