The Siberian language that preserves the echoes of Proto-Turkic

In short: Yakut is a linguistic time capsule. While it has diverged so significantly from other Turkic languages that mutual intelligibility is low, it uniquely preserves long vowels and distinct phonemes that allow scholars to reconstruct the ancient roots of an entire language family.

Spoken by approximately 450,000 native speakers in the Sakha Republic, Yakut (or Sakha) is a Siberian Turkic language. It sits within the Northeastern Common Turkic family alongside Shor, Tuvan, and Dolgan. Its development is marked by heavy influence from Mongolic languages and Tungusic groups, as well as significant recent borrowings from Russian.

Yakut is phonologically unique. It is one of only two Turkic languages—alongside Dolgan—to lack postalveolar sibilants. Furthermore, it is the only known Turkic language other than Khorasani Turkic to feature the palatal nasal /ɲ/. A striking example of its internal logic is 'debuzzalization,' a process where the phoneme /s/ becomes [h] intervocalically, a sound change also seen in Greek and Indo-Iranian.

The language's grammar is defined by complex agglutination and the most intricate system of vowel harmony in the Turkic family. In Yakut, subsequent vowels must match the frontness, lip rounding, and height of preceding syllables. This creates a highly predictable pattern where suffixes take on numerous allomorphs based on the stem they attach to. For instance, the plural suffix /-LAr/ can surface in 16 different forms depending on the preceding sounds.

While it is typically grouped with Common Turkic, its early separation from other speakers led to such divergence that some scholars, including Vasily Radlov and Otto von Böhtlingk, have historically questioned if it is Turkic at all. Despite this, its preservation of specific archaic features remains vital for historical linguistics.
