West Papuan ?
Hattam, also spelled Hatam, Atam and also known as Borai or Mansim, is a divergent language of New Guinea. It is not closely related to any other language, and though Ross (2005) tentatively assigned it to the West Papuan languages, based on similarities in pronouns, Ethnologue (2009) removed it as a language isolate.
