The Bokars are one of the sub-tribes of the Adis of West Siang District. The Bokar language has two main dialects - the Upper and the Lower. In view of the common tendency towards common medium of expression, no attempt has been made in this book to stick to any particular dialect. Its aim is primarily to enable outsiders to communicate with the local people in their language and promote mutual understanding.
