The paper discusses the al-Iltifât language style in the Arabic tradition of science. Al-Iltifât is the transition of communication patterns in the conversation. Ontologically, al-Iltifât as a style of the language regarded as the crucial part of balaghah study, because there is no unity of definition and scope of study among scholars, even the names are quite varied. In the tradition of classical study, ulama provide various names. The scope of this al-Iltifât is limited to transition on the use of pronouns, the use of verbs, and the transition of themes in the conversation context. In contrast to modern balaghah scholars who are expanding the scope of the al-Iltifât, they are not bound by the definition and scope of the study proposed by classical scholars. They depart from the general terminology that all forms of communication pattern transition are included in the al-Iltifât category. Therefore, they develop various types that have an impressive communication pattern transition.

Students who will learn Arabic have different abilities. Likewise, in terms of pronouncing the sounds of Arabic sentences, if there is an error, it will impact the meaning contained in the sentence.  The purpose of this study is to find out how the forms of phonological errors that occur in Class VIII students of MTs Negeri 1 Gorontalo City in the 2023-2024 school year, this research is a type of research using the Anakes method (Error Analysis) using a Descriptive Qualitative approach, the data collection technique is by Oral Test, and Sound Recording, while the data analysis technique uses the Ellis technique based on language error analysis using the Anakes procedure. The results of the forms of phonological errors in reading Arabic texts that researchers get in the field are students who find it challenging to pronounce Makhoriul letters by the nature of the letters so that letter swapping occurs, such as errors in swapping letters ع read أ, ذ readز, ظ is read,ز ث is read,س ض is read,د ح is read,ه and learners who have difficulty distinguishing the pronunciation of letters that are almost the same as the error أَبْدَأُ is read أَبْدَعُ, إِذَنْ is read إِزَنْ ثُمَّ is read سُمَّ, رِحْلَةٌ is read رِهْلَةٌ.

This article studies about aspects of al-iltifat al-mu’jami as one style of language in the Qur'an.  This study aims to reveal the secrets of meaning behind the use of two synonymous words interchangeably in one or more plots of speech. This type of research is a library research with an interdisciplinary approach. In data analysis using content analysis by examining the basic meaning of words that experience al-iltifat, then confirms the meaning through balaghah, syntactic, morphological, and semantic analysis. The results of the research show that there are two different styles of al-iltifat al-mu’jami in the Qur'an, namely: first, the transition of the use of a word to another word that is synonymous in a verse or series of verses in a plot of speech; and second, is the use of two words that are synonymous in a separate surahs in the same speech theme. The transitional use of the word among others is aimed at emphasizing a concept, emphasizing the difference in quality and quantity of something, affirming the nature to be highlighted, expanding the concept being talked, or perfecting the concept that is the theme of the speech. The benefits of studying about al-iltifat al-mu'jami are helping to understand the message of the Qur'an, dismissing the assumptions of the language of the Qur'an, understanding the other side of the miracles of the Qur'an, helping in carrying out a mindfulness towards the Qur'an, and developing insights on various approaches that can be used in developing Qur'anic studies from the linguistic side.
