The sentence in Arabic did not receive the attention of the early scholars in their grammatical study, and this was evident in their writings. It did not take enough of it in the study and analysis; This prompted us to follow up the case and choose a part of the sentence and its structures in the Holy Quran. So the intention was established; To clarify its meaning by studying it semantically. After extrapolation and statistics, we found that there are few recent studies that dealt with the nominal and literal connection in general, and did not obtain an independent, comprehensive, comprehensive study that stands for its semantic study, except for a few Quranic studies; Therefore, the research is concerned with the study of the patterns of grammatical structures in which the connection sentence (which) is contained, originating with (by a past tense), and the viewer of the relative link sentence (which) will find it a linguistic structure, integrated in the grammatical structure, containing the elements of the attribution that rise as an independent sentence from the sentences that have no place It has an inflection in Arabic, and this is what obligated us to study its grammatical patterns semantically.
