Temotu languages
The Temotu languages, named after Temotu Province of the Solomon Islands, are a branch of Oceanic languages proposed in Ross & Næss (2007) to unify the Reefs – Santa Cruz languages with the Utupua - Vanikoro languages. History of classification. The Reefs-Santa Cruz languages had previously been considered Papuan, but Ross & Næss (2007) established that their closest relatives were the Utupua–Vanikoro languages, previously thought to be Central–Eastern Oceanic. However, Roger Blench (2014) argues that the aberrancy of Utupua and Vanikoro, which he considers to be separate branches that do not group with each other, is due to the  fact that they are actually non-Austronesian languages. Blench (2014) doubts that Utupua and Vanikoro are closely related, and thus should not be grouped together. Since each of the three Utupua and three Vanikoro languages are highly distinct from each other, Blench doubts that these languages had diversified on the islands of Utupua and Vanikoro, but had rather migrated to the islands from elsewhere. According to Blench, historically this was due to the Lapita demographic expansion consisting of both Austronesian and non-Austronesian settlers migrating from the Lapita homeland in the Bismarck Archipelago to various islands further to the east . Languages. François (2009) notes that the lexicons of all three Vanikoro languages are highly distinct from each other and do not appear to be closely related, although their grammars are all similar.
