Reasoning history in syntax

Since a long time ago syntacticians have used reason and reasoning in their speech to proof syntactic theorms and make their speech decisive, but they have disagreed about the rate of using reasons and reasonings.While the syntactic rules becoming completed, the disagreements caused atendency among many syntacticians to use reasoning in the syntactic debates and as a result, we notice the progress and revolution of reasoning debates, proofs, and comparison in syntax. The first step in reasoning started with using simple reasons in syntax and to teach syntactic debates, it continued its progressing so that in the third and fourth centuries, we could see a big group of syntacticians who used a large amount of reasoning in syntax and wrote some merely reasoning books.The large number of reasons caused complexity in syntactic debates and opened a new window to the syntacticians who opposed reasoning in syntax.Some syntactitians tried to make the syntactic debates as simple as possible and it was the result of a group of syntacticians’ disagreement with that kind of reasoning. In this article, we have analyzed the way reasoning opened its way in syntax, its evolution, and its characteristics at different stages. The aim is to mention the historical movement of the evolution and tremendous changes which happened to syntactic rules at each stages. Meanwhile, we tried to clear the effort of syntacticians for finding the most effective way of teaching syntactic rules.
