The semantic field of the words "Za'am ", "Meryat" and "Rayb" in the Holy Quran

One of the semantic methods is Izutsu theory, which is used in the field of Quranic vocabulary. In order to extract the meaning of words, Izutsu pays attention to semantic development by looking at the meaning of words in Jahili poetry and identifies focal, key and secondary words. Then he identifies the meaning of the words with seven methods. (contextual definition, replacement of words, opposite words, semantic field, negative form of words, synonyms of expressions and usage in non-religious context) This research, after identifying the type of vocabulary, has analyzed the effect of each word in the semantic field with a descriptive-analytical method. Then, the semantics of the words Za'am ", "Meryat" and "Rayb" have been done using the implementable parts of Izutsu's theory. Through this research, it was determined that the words Za'am ", "Meryat" and "Rayb" were used in Jahili poetry, but in Quranic usage, they have the basic meaning of "false belief", "stubborn doubt" and "obstinate doubt" respectively
