This document is an English project submitted by Dhruv Goyal on the topic of "Mother Language". The project includes an acknowledgement, certificate, objective, materials required, action plan, chapters on "Mother Language" and "The Last Lesson", a questionnaire and its report, inferences, conclusion, reflections, and future scope. It discusses the importance of mother language in one's upbringing and identity. A survey was conducted through a questionnaire to understand people's use and connection to their mother language in various contexts. The inferences indicate that while families predominantly use mother language, its use is declining in professional settings due to societal pressures and the dominance of English as a global language.
