The Left May–Kwomtari or Arai–Kwomtari languages are a possible small family of Papuan languages proposed by Malcolm Ross, which links the Left May (Arai) family with the Kwomtari–Fas proposal (Loving & Bass 1964).
However, the proposal is problematic; it's not clear if the Arai correspondences are with Kwomtari, with Fas, or with both, as Kwomtari–Fas is itself dubious.
This contradicts the original classification of Loving and Bass, which is supported by their field notes.
Taking this into account weakens the case for the Left May-Kwomtari proposals.
Some relevant pronouns are shown below (Baron 1983): It appears that for proto-Arai and proto-Fas a pronoun *atie might be reconstructed for "I", and a *wa for "s/he", while for Arai and Kwomtari perhaps *na and *amwa might be reconstructed for "you" and "they", with the former perhaps including Pyu as well.
