Kolyma Yukaghir and Tundra Yukaghir are not mutually intelligible. Both Yukaghir languages have residual vowel harmony and a complex phonotactics of consonants, rich agglutinative morphology and are strictly head-final. They have practically no finite subordination and very few coordinate structures. Yukaghir has a split intransitive alignment system based on discourse-pragmatic features. In absence of narrow focus, the system is organised on a nominative–accusative basis; when focused, direct objects and subjects of intransitive verbs are co-aligned (special focus case, special focus agreement).
