Sociolinguistics Aspects of Globalization and Knowledge Economy: The Effect of English on Urdu Lexicon This thesis studies language change in the Urdu language due to the incorporation of English words. Globalization and its economic counterpart, the knowledge economy, provide the theoretical framework for this study. Embedded in the tapestry of linguistic processes, these socio-economic factors offer a uniquely economic perspective on semiotics. As the global village rids itself of the shackles of Babel, English emerges as the connecting principle of its inhabitants. Enabled by information technologies, the global scale is the new dimension for linguistic interaction. The murky maya of a global world order blurs the spatial boundaries of languages, promoting an exchange of lexical elements. This research focuses on lexical changes in the Urdu lexicon in a global world. The predominantly English origin of the words borrowed by Urdu in the present global phase of its evolution is a continuation of a tradition of lexical borrowing from Persian and Arabic. Languages, embedded in the cultural apparatus of globalization are manifest as "resources". The English language is the non perishable raw material of the knowledge economy. Ushered in by the deepening twilight of capitalist economies, the knowledge economy model is the sustaining principle for developing nations like the home of Urdu i.e. Pakistan. Urdu thus borrows vocabulary from English, the established resource base of the knowledge economy in order to carve a niche' in global economic markets. Content Analysis of two dictionaries is undertaken for the analysis of language change. The global scale emerges from the timeline under which lexical changes are classified. It reveals that the process of language change speeded up post 1947. It is concluded from the findings, that the words which are becoming a part of the Urdu language from English ordain an enriching positivity to its repository. From concepts like "globe", "international", "biography", "award", "imperial", "modernism" to everyday terms like "hand", frock", "dish", "fur", "jelly", "cup", Urdu emerges as a tireless and indefatigable borrower of words from the entire spectrum of the English lexicon. Language change is the resurrecting panacea of the Urdu language struggling to meet the communicative requirements of the 21st century.
