The first time such a newly emerged linguistic variety has been documented at NUML, Islamabad. This language variation means morphological, semantic, connotative deviations from standard linguistic norms. Contact linguistics, code meshing, diversified linguistic backgrounds and their colloquialism play their vital roles in shaping Numlianlect of BS English. The research problem faced by learners of super standard language is that they do not comprehend the newly code meshed discourse in the informal settings of NUML. So, this research raises questions about the exploration of linguistic variations, their formulation process and their denotative and connotative semantic shades. To answer these questions, qualitative and survey-based research design has been employed. The collected data have been analyzed with Labov and Weinreich’s Variation Theory (1960). Major findings reveal that students mix English, Punjabi, Sindhi, Pashto and Urdu words to produce variant code-meshed linguistic patterns. Connotation, semantic shades and contexts of words have been changed by students.
