Vella Lavella
Bilua (also known as Mbilua or Vella Lavella) is the most populous Papuan language spoken in the Solomon Islands. It is a Central Solomon language spoken by about 9,000 people on the island of Vella Lavella. It is one of the four non-Austronesian languages spoken in the Solomon Islands. The number of different languages spoken in the Solomon Islands is attributed to the dynamic geographic features of the island and the isolation of its different populations.
