The Tambora language was a language isolate spoken on the island of Sumbawa, in modern-day Indonesia, until 1815, when the entire speech community was erased by the eruption of the Tambora volcano.
Tambora was actually one of the first languages I ever did any work on, starting in 2018 when I was still in high school. My first projects on it (which will never be posted publically) were of a historical-comparative bent, aimed at establishing a genetic relationship between Tambora and some Papuan languages spoken further east. My current work is focused on expanding the very small existing corpus of data on Tambora, via the study of Tambora toponyms and anthroponyms recorded in colonial-era Dutch records. Hopefully one day I'll have enough onomastic data collected to merit publication. For now, unpublished drafts can be found on this website.
