Because without choosing the correct wording (mufradāt) in Arabic texts, it will result in the inability of students to understand the lesson well. This study aims to reveal the vocabulary used by Arabic books and the suitability of the wording with the theory initiated by Ahmad Rusydi Thu’aimah. The method used in this study is a qualitative method using content analysis as a technique in research.
