nam- and rēž-, Two Sogdian Impersonal Verbs

The Impersonal verb is a verb which is always inflected in the third singular and its logical subject does not appear in the nominative case. These verbs often express physical or mental/cognitive experiences which the logical subject experiences without having any control on them. Thus the subject in these structures is called "experiencer". Another element which has a role in impersonal sentences is the source of the events, activities and experiences. It's presence in the sentence depends on the meaning of the verb. In Sogdian beside some of the modal verbs which are in accordance with the definition of impersonal verbs, there are two other verbs which are impersonal too. These are rēž- and nam-. As will be shown rēž- is appeared as an impersonal verb approximately in all the remaining evidences, but nam- has impersonal use just in one of it's evidences. In this article I will study and analyze these two verbs.
