Undoubtedly, hyponymy is one of the most important and well-known conceptual relationships at the lexical level. This relationship occurs when the concept of one word encompasses several other concepts. Among other conceptual relationships, hyponymy is particularly significant in elucidating the semantic field of words, as it can facilitate the understanding of other conceptual relationships. The word "Fazl" (grace), as one of the prominent attributes of God in the Holy Quran, holds a special place and plays a central role in shaping the Islamic worldview. Therefore, it is essential to discover its semantic domain within the semantic network of the Quran. By uncovering the hyponymy relationship of "Fazl," the position of this concept in the Islamic worldview becomes evident. This descriptive-analytical research analyzes and elucidates the semantic hyponymy of "Fazl" in the verses of the Holy Quran in chronological order of revelation based on structural semantics and relational semantics. The findings indicate that the core meaning of "Fazl" denotes the concept of abundance and the word has been used beyond its literal meaning in the Holy Quran, encompassing a wide range of meanings. It has a hyponymic relation with words such as inheritance of the book, selection, success in preceding others in good deeds, the abode of permanence, knowledge of the speech of birds, the presence of the throne of the Queen of Sheba, delay in punishment, monotheism, the harmony of mountains and birds with Prophet David (peace be upon him), the system of day and night, the gardens of paradise, eternity in heaven, etc.
