Introduction

Ata Manobo is a language spoken by a people group in the southern Philippines on the island of Mindanao, in northwest Davao del Norte Province and in southeast Bukidnon Province.

The Ata Manobo language has been referred to as Ata of Davao and Langilan.

This dictionary is based primarily on the dialect of Ata Manobo which is spoken by people located in the vicinity around the northern portion of the Liboganan River which flows into the Dawao River.  This area is now being referred to as the Langilan dialect even though the actual village of Langilan is far upstream (north) of Mansalinao where the original dictionary was compiled.  The entire Ata Manobo estimated population of between 20,000-40,000.
