"The distribution of Uilta is closely connected with their half-nomadic lifestyle, which involves reindeer herding as a subsistence economy.
The Northern Uilta people live near the Terpenija Bay and the Poronai River during spring and summer and migrate to the East Sakhalin mountains for autumn and winter.
Takeshiro Matsuura (1818–1888), a prominent Japanese explorer of Hokkaido, southern Sakhalin, and the Kuril Islands, was the first to make a notable record of the language.
The oldest set of known records[clarification needed] of the Uilta language is a 369-entry collection of words and short sample sentences under the title "Worokkongo", dating from the mid-nineteenth century.
Other researchers who published some work on the Uilta were Hisharu Magata, Hideya Kawamura, T.I Petrova, A.I Novikova, L.I Sem, and contemporary specialist L.V.
For example, the element – ɲɲee (< *ɲia), has become a general suffix for 'humans', as in ǝǝktǝ-ɲɲee ‛woman’, geeda-ɲɲee ‛one person’ and xasu-ɲɲee ‛how many people?’.
[dubious – discuss] Uilta has participial markers for three tenses: past -xa(n-), present +ri, and future -li.
