This document discusses the relationship between language, culture, and identity. It argues that language and culture influence each other mutually - language is shaped by culture but also shapes culture. Membership in a cultural group influences one's identity. The levels of identification conveyed through language include nationality, social class, gender, generation, and profession. Language determines ways of thinking through influencing cognition as proposed in the Sapir-Whorf hypothesis. Overall, the document presents language, culture and identity as intricately interconnected and constantly evolving.
