This chapter introduces the concepts of intercultural communication and culture. It provides practical reasons for studying intercultural communication, such as adjusting to a global workplace, adapting to domestic diversity, and enhancing intercultural relationships. The chapter defines culture as a learned meaning system consisting of patterns of traditions, beliefs, values, norms, meanings, and symbols shared within a community and passed down between generations. Culture is compared to an iceberg, with surface-level culture being popular culture and deeper levels including cultural norms and shared traditions.
