The present article aims at studying the various types of the usage and meaning of Quranic vocabulary and the ways of revealing their intended meanings. Referring to three types of verbal, conventional, and religious usages of Quranic terms, analyzing the concept of coinage particularly from the perspective of Shiite jurisprudence logicians, and expressing the role of Quranic context and culture in determining the meanings, we may put the Quranic terminology into three categories, i.e. verbal, conventional, and peculiar Quranic meanings. Then we would pursue step by step the three types of meanings, i.e. the original sense, the common conventional meaning at the time of revelation, and the meaning originating from the particular Quranic culture, as the influential indices in understanding Quranic concepts.
