ABSTRACT
Here the concept of evidentiality as the linguistic encoding of the source of information has been introduced, and the pragmatic functions of it in language have been explained: commitment to the information, reliability, precision, and even trust. It will be clarified that languages vary in terms of evidential marking. Turkish, for example, marks evidentiality by morphological endings; Persian by impersonal passive forms, modal expressions, tense-aspect features, reports and quotations, and sensory and perception verbs. Other linguistic devices for marking evidentiality in the world languages are explained. Finally, evidentiality is discussed as a means for narrations of stories in literature.
