Meghalaya is bounded on the north and east by the state of Assam and on the south and west by Bangladesh. The word "Meghalaya" literally means the Abode of Clouds in Sanskrit. The state is inhabited by three ethnic communities -- the Khasis, the Jaintias and the Garos – each of which follows its own cultural traditions and customs. The common trait binding all three communities is its matrilineal system in which the family linage is taken from the mother's side. The people of Meghalaya are known to be hospitable, cheerful and friendly. The state’s area is divided in Khasi hills, Jaintia hills and Garo hills. The forests of Meghalaya are notable for their biodiversity of flora and fauna.
