No definition of the phrase "al-Vojuh wa-al-Nazair” is found in the oldest works written on this subject. The first definition was provided by Ibn-e- Jozie and after him, other definitions were proposed. In addition to internal discrepancies, these definitions are not consistent with examples of "al-Vojuh wa-al-Nazair” provided in relevant books. The problem of differences in definitions and examples is also observed in the sources of Quranic sciences. The purpose of this article is to examine the differences in definitions and to discover the most appropriate definition. In this documentary research, a descriptive -analytical approach was used. The paper conducted a comparative analysis of presented examples and definitions, reviewed different definitions and concluded that “Vojuh” are the different meanings of a word and “Naza’er” are similar words which have different meanings in different verses. As a result, the definition of Ibn-e- Jozie is consistent with the examples of the antecedents and is, therefore, the most appropriate definition.By paying attention to the examples of "al-Vojuh wa-al-Nazair” in the antecedents’ books, it becomes obvious that “Naza’er” implies both the similarity of terms and the similarity of their meanings, but this stipulation is not mentioned in any of the definitions.
