literally hill people Meghalaya

The Garos are indigenous people in Meghalaya, India and neighboring areas of Bangladesh, who call themselves A·chik Mande (literally "hill people"). 

They are the second-largest tribe in Meghalaya after the Khasi and comprise about a third of the local population. The Garos are one of the few remaining matrilineal societies in the world.

The Garo language belongs to the Bodo–Garo branch of the Tibeto-Burman language family. The language was not traditionally written down; meaning, customs, traditions, and beliefs were handed down orally. It is also believed that the written language was lost in its transit to the present Garo Hills.

The Garo language has a few different dialects.
