Papua Island consists of Papua (Western part of this island) belongs to the country of Indonesia while the other Eastern side is the country of Papua New Guinea (PNG). Let me say that this island is an exceptional spot in this planet which contains approximately thousands of languages. Due to variety of linguistic systems over so many ethnics, a language or dialect must be exercised among citizens. Papua (used to be called Irian Jaya) and its people converse in Bahasa Indonesia as an interactive language, while PNG citizens speak both Pidgin and English as a Second Language. Thus, in order to speak among Papuans, a dialect of Indonesian version has been exercised, which is called Malay Papuan. This paper describes the distinctive features of this dialect version particularly its phonemic, morphemic systems. Prior to that, a glance concept of a dialect in its term and meaning and a brief historical of Malay dialect of Papua are presented.
