Studying the Syntactic Position of Complement Clauses in Persian Language Based On Dependency Grammar

Complement Subordination is a process that the verb accepts a complement clause as one of its obligatory dependents, and its omission makes the sentence ungrammatical. Regarding the structure, the verbs which accept complements can be simple verbs (danestan, goftan), verbs with prefixes (vagozashtan), and compound verbs (ragham zadan, agah kardan).The corpus of this research includes one thousand sentences of contemporary Persian stories. Dependency grammar is one of the formalist theories of grammar that considers the relationship between a head and its dependents in analyzing the syntactic structures. Syntactic structures of Persian language show that some verbs have one complement clause, thereby having a compliment clause is one of the specific features of the verb of the main clause. The present study tries to give a detailed description of complement clauses in Persian. In order to do so, the process of subordination will be analyzed in complex sentences in which the complement is the subordinate clause and depends on the main clause. It could be said that complement clauses which are made by the inflectional forms of the verbs, are often placed in the syntactic position of obligatory dependents of the verbs (subject, object, prepositional object).
