Ese is a language of Oro Province, Papua New Guinea. Although it is also known as Managalasi, which the Summer Institute of Linguistics regards as pejorative possibly because it is a corruption of Hiri Motu phrase meaning the equivalent of "know nothings", the term "Upper Managalasi" indicates Ömie, another member of Baraic languages. Dialects are Muaturaina, Chimona, Dea, Akabafa, Nami, Mesari, Averi, Afore, Minjori, Oko, Wakue, Numba, Jimuni, Karira. Perhaps 40% of speakers are monolingual.
