THE ROLE OF LINGUISTIC ECOLOGY IN SHAPING LANGUAGECONTACT IN URBAN PAKISTAN: A SYSTEMATIC REVIEW OFTHEORETICAL FRAMEWORKS AND EMPIRICAL EVIDENCE

Abstract

This systematic review investigates how linguistic ecology shapes language contact dynamics in urban
Pakistan, with particular focus on Karachi, Lahore, Islamabad, Quetta, and Peshawar. Despite
Pakistan’s extensive linguistic diversity, research on language contact has largely emphasized structural
outcomes such as code-switching and borrowing while paying limited attention to the ecological
conditions that influence multilingual practices. Guided by theories of language ecology,
translanguaging, metrolingualism, language ideology, and feature-pool ecology, the review synthesizes
evidence from 25 peer-reviewed studies published between 2012 and 2024. Following PRISMA-informed
review procedures, studies were analyzed through a thematic and theory-driven framework to identify
recurring patterns across urban multilingual settings. The findings reveal that Pakistani cities constitute
stratified multilingual ecologies in which Urdu functions as the principal contact language, English
serves as a prestige-bearing and gatekeeping resource, and regional languages such as Punjabi, Sindhi,
Pashto, Balochi, and Seraiki experience varying degrees of institutional marginalization. Language
contact is shown to be shaped by interconnected ecological factors, including educational policy,
migration, socioeconomic inequality, linguistic ideologies, and spatial organization of urban
environments. Code-switching and translanguaging emerge as adaptive communicative practices through
which speakers negotiate identity, social mobility, and access to linguistic capital. The review further
identifies significant gaps in existing scholarship, including the absence of longitudinal ecological
research, limited attention to gendered language practices, and insufficient examination of digital
communication spaces. The study proposes an Urban Linguistic Ecology (ULE) framework that
integrates spatial, ideological, institutional, interactional, and temporal dimensions of language contact.
By contextualizing Pakistani multilingualism within contemporary sociolinguistic theory, the review
contributes a comprehensive analytical model for future research, language policy development, and
multilingual education planning in postcolonial urban settings
