Mirza Habib's understanding of the tense category

According to a number of modern grammarians and linguists, one of the significant inaccuracies of traditional grammars is their failure to dissociate the categories tense, mood, and aspect. This study at first defines the concepts of ‘tense’, ‘mood’ and ‘aspect’ and delineates the boundaries of them and then examines the concept of ‘tense’ in the most important grammar works of Mirza Habib Esfahani, dæstur-e soxæn and dæbestan-e parsi. This study shows that Mirza Habib was aware of the distinction between time and tense and explicitly mentions this distinction. He also distinguishes tense from mood and implicitly dissociates aspect from tense.
