On the Emergence of Scientific Grammar in Iran Ali

Writing the grammar of a language is one of the most significant outputs of linguistic studies. In Iran, it is Avicenna (Ibn-e Sina) who is credited with the first such compilation of the Persian language. Under-standing the weaknesses associated with the traditional trends of grammar writing in Iran, contemporary Iranian linguists adopted the modern Western approach following the Chomskyan Turn thus attempting to work out a grammar for Persian. Accordingly, this study investigated the scientific theory of grammar writing in Iran through a descriptive-analytic method, using the transformational-generative theory. In addition to reviewing the stances of Iranian grammarians, the paper specifies and describes grammars of different kinds through a typological approach so as to attain a new classification of grammar writing par-adigms in Iran. The findings of this research show that grammar writing approaches in Iran are divided into three paradigms, namely, traditional, structural, and scientific.
