Syntactic Processes Dealing With the Derivation of WH- Multiple Questions

The purpose of this study is to investigate the syntactic processes involved in deriving Persian WH-multiple questions. Therefore, the function of WH-words in these constructs regarding the syntactic processes is examined. It also clarifies which syntactic functions justify their sequential or split orders. The research method is descriptive-analytic on the base of  Chomsky’s Minimalist approach (1995). Research data was collected from books, Media, newspapers, social networks and Google search engine and native speakers’ speech. Data  analysis shows that in sequential WH-multiple questions (both types), backward deletion occurs in which the identical constituent in the first clause is deleted under identity. In these constructions, the first WH-word remains in situ and the second one moves to the focus phrase after deleting the identical constituent. Scrambling is just possible with adjunct- adjunct and adjunct- argument order in these constructions. In split WH- multiple questions, the deletion of identical constituent occurs in the second clause as forward deletion in which  both WH-words remanin in situ. Scrambling in these constructions is also possible with adjunct-adjunct and adjunct-argument order. Scrambling and superiority of WH-words are not permitted in WH-multiple questions with any order of WH-words.
