The Central Siberia hotspot contains few languages compared to other hotspots. However, it holds six genetic units, four of which have only one living language. It is notable, therefore, for its genetic diversity, and for its extreme endangerment. Many Siberian languages have been lost in the last few generations due to Russian-only government policies, and many living languages in the area have only a few elderly speakers.

One moribund language of the area is Tofa, which is now spoken by fewer than 30 people, all of them elderly. The Tofa people were traditionally reindeer herders and hunter-gatherers. Their language includes a complex classification for reindeer, which allowed reindeer herders to provide a large amount of detail in just one word. For example, the word döngür means ‘male domesticated reindeer in its third year and first mating season, but not ready for mating.’ Now most the Tofa people speak Russian, which has no equivalents for words like döngür.
