The Australian National University, Research School of Pacific Studies, 1988. — 222 p. — (Pacific Linguistics: Series B 100).This study is based upon a M.A. Linguistics thesis written by the author at The University of Texas at Arlington. This revision and update represents a continuing investigation of the Una language. As such it is still only the beginning of fully explicating the intricacies of this non-Austronesian language of the Central New Guinea Macro Phylum.
The Una language is spoken by approximately 3500 people living in 40 villages and hamlets along the southern slopes of the central cordillera of the Pegunungan Jayawijaya (Orange Mountains) in the Ey, Sayn, Mo, Yamiyl, Kiynok, Ira, Mina, Be and Yay River valleys.
