Persian Conditional Construction Patterns based on Verb Forms

Persian verb forms in conditional constructions and consequence clauses are complicated in terms of tense, modality. The various verb forms can be problematic in teaching Persian to foreign language learners in understanding and using them. Although there are lists of possible types of conditional constructions of Persian, it seems that none of them provides an exhaustive list of all variations. Therefore, the objective of this research was to provide a more comprehensive classification of TMA (tense-mood-aspect) of verb forms in conditional constructions from a corpus of about 400 compound conditional sentences collected from a vast number of sentences of dialogues and other spoken discourses, chat communications, and contemporary written texts. After investigating and classifying various manifestations of verb forms in both conditional and consequence clauses, it was turned out that there are 10 verb forms in conditional clauses forming 44+4 types of conditional constructions, and 10 verb forms in consequence clauses forming 44+4 types of conditional constructions: 44 different combinations of conditional and consequence clauses, and 4 types conditions with just conditional clause Therefore, new uses of verb forms in Persian conditional constructions were found.
