Since the personal suffix on the verb unequivocally refers to the number and the person of the subject in Surgut Khanty, personal pronouns are optional. If the context disambiguates the referent of the third person singular subject, it can also be dropped. If the personal pronoun is present in the sentence as the subject, it serves an emphatic function.
