prominent context's elements which Sibawayh paid attention to it .

- The title of the second chapter's research is "A methodical and procedural steps befor laying dwon the syntactical rules، and the declensional guiding . In this research، I made mention of the systematic steps of Sibawayh which he followed . It is summarized in four elements:

a. Classifying the language into a abstracted and stereotyped structures .

b. Numerical computation for the abstracted and stereotyped structures .

c. Tracing the definitive، lingual structure different contexts and binding the lingual structures with the meaning of these contexts .

d. Living with the lingualstructures in its pronounced texts .

The three following chapters in the thesis brought forward the scientific dentations from Sibawayh's Kitab . These dentations verify the effects of context on Sibawayh's laying dwon the syntactical rules . So، the title of the second chapter was "the context's role in declensional guiding" . It contained the succeeding researches:

١) " context's importance in declensional guiding" . I indicated in this research that there are declensional structures do not be correct، it has not an entity، and we can not guide it declensionally but through context's evidence . I named that Sibawayh exploited the context in his declensional guiding . In this research، I stated that thecontext may be a reference to the pronoun in case of nonexistence of linguistic reference . I also cited that we will fail to take advantage of context، if we do not exploit it in our lingual analyzation .

٢) The second research in this chapter: "Enrichment of context for semantic، and declensional guiding . Deeply،I discussed in this chapter the role of context in enrichment of declensional guiding . I repoted here that the speaker's condition، his silence's potentialitydeclensional guiding، his will، and his psychological
