As with all things in the humanities, oftentimes concepts overlap with each other and change over time. For instance, one paper you write might easily talk about both intracultural and intercultural communication, or you may start a paper from the intercultural perspective and move up to a more general cross-cultural perspective. Also, as people change, the communication between them changes. Take the example of an intercultural friendship…it’s intercultural in the beginning because the two people might be from different cultures. However, if that friendship lasts for many years, they will learn enough about each others cultures to completely change the dynamic of the communication in their relationship and make it an interpersonal one instead.
