<![CDATA[Nahwu (Arabic grammar) and ilmu lughah at-tathbiqi (applied linguistics) are two disciplines that share a functional interconnection in Arabic language learning, yet studies examining both in an integrative framework remain relatively scarce. This article aims to examine and analyze the relationship between nahwu and ilmu lughah at tathbiqi in Arabic language learning through a library research approach. The study employs a descriptive-analytical method, with data collected through systematic documentary review of primary and secondary sources, including reputable national and international journal articles and works by modern Arabic linguistics scholars. Data analysis was conducted using three complementary techniques: content analysis, thematic analysis, and comparative analysis. The findings reveal that the interconnection between nahwu and ilmu lughah at-tathbiqi manifests across three main dimensions: (1) the theoretical dimension, reflected in the paradigm shift from al-nahwu al-'ilmi to al nahwu al-wazhifi as a concrete expression of the intersection between grammar and the communicative orientation of applied linguistics; (2) the analytical dimension, embodied in error analysis (tahlil al-akhtha') and contrastive analysis instruments that rely on grammatical rules as normative standards and diagnostic tools; and (3) the pedagogical dimension, evident in curriculum development, material gradation (tadarruj), and authentic assessment informed by applied linguistics principles. The study concludes that the integration of both disciplines produces Arabic language learning that is grammatically accurate as well as communicatively meaningful. This article recommends that Arabic language educators and curriculum developers in Indonesia adopt an integrative approach between nahwu and applied linguistics in designing more contextual and effective Arabic language pedagogy.]]>
