The early studies on text grammar appeared in the late 1980s. Maslouh was among the few founders of this field in Arabic studies. However, his contribution has not been fully acknowledged in spite of its originality, richness, and importance. The current study aims at bridging this gap by shedding lights on Maslouh’s contribution to text grammar. It will study the major aspects of his three researches on the area. The study will describe his work and compare his theoretical backgrounds to his analysis and introduce a final discussion and results. The importance of this work emerges from the integrity of Maslouh’s writings and the vividness of his perspectives as well as the comprehensiveness of his analysis.
