The researcher of simplification of grammar and reform taking bold views in these researchers areas of interest trying to criticize and highlight the impact of these studies on the old grammar school of thought and tackling the problems and difficulties and providing what he deemed as appropriate to the teaching of grammar. The researcher divided his thesis into an introduction, three chapters and a conclusion noting down the most important findings. In the first chapter he discussed the topics the adherents of simplification decided upon in three chapters: In the first, the elimination of agent, in the second syntax is form or function and in the third the reasoning. In the second chapter the researcher investigated the methodology of the adherents of simplification starting with an introduction followed by three chapters: The first addressed those who criticized the old methodology; the second the call to study the sentence and the third a discussion of the advantages of studying the sentence. The third chapter contains two units: the first is the study of method and the second the methods which we call for studying away from attribution. This chapter summarizes the most important findings, which are: 1. The old grammatical lesson, apart from what Sibawayh introduced in his book, is regarded as seemingly disconnected topics, which prompted the adherents of simplification to criticize it proposing an alternative method with a wide discrepancy between them. 2. Researchers on the subject of the sentence tried to give it a watertight definition to shift it away from formalism to attribution to rid it of many unnecessary estimates and issues. 3. An amount of language lesson should be included in the grammatical approach under the title Images of Expression in these approaches without involving it in attribution and syntax.
