The given article dwells on the issue of the morphological peculiarities and functional integration of Arabic-derived adverbs in Muhammad Iqbal`s poetry. The article illuminates the processes of integration, re-grammaticalization, and stylistic utilization of these adverbs revealing their role in shaping Iqbal’s distinctive poetic idiom. The findings demonstrate that these adverbs not only enrich the Persian lexicon but also contribute to specific rhetorical effects, modal nuances, and a heightened sense of classical or philosophical gravity, thereby transcending mere lexical borrowing to become integral to the poem’s aesthetic and semantic fabric. Thus, the conducted analysis underscores the linguistic fusion characteristic of Iqbal’s work and its implications for understanding the historical interplay between Arabic and Persian literary traditions.
