Morphological and Syntactic Constraints of Productivity in Persian Derivation

There is a variable of constraints imposed on word formation processes. The more constraints there are, the less productive the process. Some of the constraints are structural among which are morphological and syntactic ones. The morphological constraints are the morphological category of the base, the morphological structure of the base and the affix in the outmost layer of the base. The syntactic constraints include subcategorization frame and argument structure constraints.
