This document provides information about a student named Nikunj Bhatti enrolled in the 3rd semester of an M.A. program in 2014-2016. It discusses several key topics in sociolinguistics, including how language use varies based on social factors like age, gender, and profession. It also examines how language changes spread between groups and styles, and how these changes can be studied through apparent time studies, real time studies, and analyses of social status and gender. The document further distinguishes between micro-sociolinguistics, which focuses on dialect and style variation, and macro-sociolinguistics, which explores issues like language retention in immigrant communities.
