Intercultural communication involves understanding how people from different cultural backgrounds communicate. Culture provides ways of thinking and interpreting the world that are shared by social groups. Culture is passed on through communication, which reflects one's culture. There are various constraints like cognitive frames of reference, behavioral rules, and display of emotions that affect intercultural understanding. Low- and high-context communication styles differ in their use of explicit messages versus implied meanings. Individuals may use a mix of both styles depending on relationships, situations, and goals.
