The Lamalama language, also known by the clan name Mbarrumbathama (Austlang) or Mba Rumbathama, formerly known as Lamu-Lamu or Lama-Lama, is a Paman language of Queensland, Australia. Lamalama is one of four languages once spoken by the Lamalama people, the others being Morrobolam (Umbuygamu), Mbariman-Gudinhma, and Umpithamu. [3]
In January 2019, the ISO database changed its reference name to Lamalama, from Lamu-Lamu. [4] As of August 2020 [update] , Glottolog calls it Lamalama, [5] while AIATSIS' Austlang database thesaurus heading is Mbarrumbathama language. [6]
Austlang says, quoting linguist Jean-Cristophe Verstraete (2018), that Lamalama, Rimanggudinhma (Mbariman-Gudhinma) and Morrobolam form a genetic subgroup of Paman known as Lamalamic, "defined by shared innovations in phonology and morphology". Within this subgroup, "Morrobolam and Lamalama form a phonologically innovative branch, while Rumanggudinhma forms a more conservative branch". [7]
