<![CDATA[Language contact in multilingual societies gives rise to various linguistic phenomena that reflect interaction, influence, and adaptation among languages. In the context of Arabic use, these phenomena may take the form of code-switching, Arabization, language transfer, interference, and language integration. Although these five phenomena are interconnected within processes of language contact, each has distinct characteristics, mechanisms, and functions, requiring clearer and more systematic conceptual distinctions. This article aims to comparatively analyze the characteristics, mechanisms, contributing factors, and conceptual relationships among code-switching, Arabization, language transfer, interference, and language integration from a sociolinguistic perspective. This study employs a qualitative approach using library research. Data were obtained from relevant academic sources and analyzed through content analysis by comparing the five phenomena in terms of their definitions, mechanisms, contexts of occurrence, degree of speaker awareness, and level of acceptance of linguistic elements. The findings indicate that although the five phenomena fall within the domain of language contact, they operate along different dimensions. Code-switching primarily involves the alternation of linguistic codes in interaction; Arabization concerns the adaptation or formation of linguistic elements within Arabic; language transfer refers to the influence of previously acquired linguistic knowledge on the use or acquisition of another language; interference involves cross-linguistic influence that may result in deviations from the target language system; while language integration refers to the more established acceptance of linguistic elements into the recipient language system. The comparative analysis demonstrates the importance of distinguishing these five phenomena according to their mechanisms, degree of permanence, and status of linguistic elements to prevent conceptual overlap in sociolinguistic studies of Arabic.]]>
