Translinguistic Oscillations and the Persian-Urdu Semiotic Construct in Kazi Nazrul Islam's Poetics: A QuantumSemiotic Approach to Bilingual Liminality

Kazi Nazrul Islam's literary oeuvre is located within a linguistic event horizon, wherein Persianand Urdu function as intertextual semiotic domains rather than lexical intrusions that destabilise thephonological, syntactic, and semantic topography of Bengali. This paper examines the structural, affective,and epistemic consequences of Nazrul's Persian-Urdu interpolations through a Quantum-Semiotic lens,investigating how these translinguistic components work as superpositional signifiers that elude monolingualcollapse. The paper then utilises Bakhtinian heteroglossia, Peircean abductive semiosis, and Foucaultiandiscourse analysis to situate Nazrul's linguistic practice within the larger Indo-Persianate epistemic regime.Finally, this paper theorises Persian and Urdu not as singular linguistic influences but as entangled quantumlexical states destabilising linear Bengali literary historiography and generating a bifurcated aestheticconsciousness swinging between the Persianate cosmopolis and the nascent Bengali national imaginary
