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]
Lamalama's vowels do not show contrastive length.[17] There are two diphthongs, /ia/ and /ua/.[18]/ia/ can raise to [iɛ], and /ua/ can raise to [uɔ].[19]
