In Synja Khanty, the verb ūlti ‘be, exit’ is used as the copula. Usually, the copula does not appear in the present tense (1a), (3), except next to a few adverbials (4). Otherwise, if it is used in a present tense clause, it expresses the meaning ‘to live’, or it has an emphatic function (cf. Nikolaeva 1999a: 40‒42, S. O.). In the past tense (1b)-(2), the copula is conjugated in the same way as other verbs.
