Ways of expressing subjunctivity and uses of subjunctive forms in Persian

Among non-indicative verbal forms, subjunctive is of most uses. This form not only plays the most important functions in expressing modal concepts, but also has a close relationship with 'aspect'. In this paper, the ways in which subjunctive concepts are expressed different uses of subjunctive forms are studeid. Based on the findings of the research, there are at least six ways in which modal concepts are expressed in Persian all of which carry subjunctive forms. Subjunctive forms play at least fifteen different functions which are divided into two categories, namely, prototypical vs non-prototypical. All these functions share one feature: there is no guarantee for the actualization of the event or situation in question. As far as meaning is concerned all subjunctive forms function within a single network in center of which there exists a prototypical meaning. All other non-prototypical meanings are derived from this prototypical meaning.
