Paying attention to the linguistic level of the Quranic discourse and the precise explanation of the verses are essential topics in the field of Quranic studies. Understanding the text and discovering the meaning in the light of other verses and through intratextual relationships are concerns of the contemporary method of semantics and are considered an important principle in understanding the discourse of the text. Although at present and in view of the needs of the present era, new methods have emerged in the field of understanding the text, all of these have their roots in traditional methods and we still need to utilize and model traditional methods such as the method of interpreting the Quran by the Quran, because the traditional method of interpreting the Quran by the Quran has had a brilliant achievement in understanding and receiving the meanings of Quranic propositions. Therefore, the present study seeks to examine the foundations of linguistics and semantics of Allameh Tabataba'i in interpreting the Quran using a descriptive-analytical method in order to reveal the interaction and alignment of these two methods from ancient times to the present. Among the foundations of Allamah's linguistics are: speaking in a rational conversational manner, the lexical and structural rhetoric of the Quran, and the meaningfulness and enlightenment of the Quranic statements. Among the foundations of Allamah's semantics are: the relationship between words and meanings, the evolution of the meaning of words over time, a context-based approach to the words and verses of the Quran, the use of Gharr verses, etc. Although the foundations of understanding the text in contemporary linguistics may have evolved slightly, they have many similarities with the traditional Quran-to-Quran method.
