Hatam (also spelled Hattam, Atam) is a divergent language of New Guinea. Apart from Mansim (Borai), formerly listed as a dialect, 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 and Glottolog list it as a language isolate or small independent family.
The phonology of the Hatam language is listed below. In free form, both consonant and vowel phonemes can range to different sounds.
