In this research, we have sought to study the transformed synthetic structures in Sahih Al-Bukhari according to the Modern Khalilist theory approach, by relating those transformed structures to their original bases, in order to interpret what this transformation has made structurally, semantically, and pragmatically. And to achieve this, we have talked about the Modern Khalilist theory, revealed its approach and principles, and the grammatical and linguistic types of transformation in the synthetic structures. Also, we have discussed the impact of verbal and non-verbal contexts on the occurrence of the transformation as well as the pragmatic effects of the transformed synthetic structures . We have concluded with the findings we could reach. The most important one of these findings is the direct contribution of the transformed sentence context to the occurrence of the transformation, and the clarity of its connotations and pragmatic effects
