Languages of the Solomon Islands
There are between sixty and seventy languages spoken in the Solomon Islands. Most of these are Austronesian languages, though the Central Solomon languages such as Lavukaleve constitute an independent family. Two other language families are represented on Bougainville, which is geographically part of the Solomon Islands, if not within the national boundaries. The lingua franca is Pijin, and the official language s English.
The status of the Reefs – Santa Cruz languages were once thought to be non-Austronesian, but further research found them to be divergent Austronesian languages. The neighbouring languages of Vanikoro are also heavily relexified Austronesian languages.
An indigenous sign language, Rennellese Sign Language, has gone extinct.
