This study is concerned with the two senses of the term "impersonal" in discourse analysis as well as in grammar. In the former, this term is applied to express indirect speech and good manner. In the latter, it denotes: impersonal pronouns, impersonal verbs, and impersonal constructions. Following this general discussion, the present study focuses on the two main groups of impersonal constructions in Mazandarani, ending with some pragmatic remarks on the use of impersonal constructions.
