Ross (2005) tentatively classified Hatam as a branch of the West Papuan family, based on similarities in pronouns (he did not consider Mansim), but Glottolog continues to list Hatam–Mansim as an independent family.[1] Following Reesink (2002), Glottolog lists Mansim as a language distinct from Hattam: "comparisons of old wordlists (e.g. von der Gabelentz & Meyer 1882) readily confirm this difference."[2]
