Final answer:
The term indicating that an individual has abandoned their home country traditions is typically 'cultural assimilation' or 'acculturation'. This often occurs when someone has spent considerable time in a different culture and prefers new cultural norms over those of their homeland.
Step-by-step explanation:
The term that indicates an individual has abandoned all of their home country traditions could be 'cultural assimilation' or 'acculturation'. When someone fully adopts the cultural norms of another society, to the extent of rejecting their origins, it could also be described as a loss of cultural identity. This can happen when an exchange student or a sociologist spend a significant amount of time in a different culture.
For instance, after an extended stay abroad, an individual may experience such a change in perspective that they find it difficult to reintegrate into their original culture, possibly rejecting the values they once held. In the case of the American in Italy, although there might be an initial glorification of one's own culture, over time and with deeper engagement, an individual might begin to prefer the new cultural practices to those of their homeland.
Desacralized points that the individual no longer holds their culture's traditions as sacred, whereas diaspora refers to a group of people who no longer live in their homeland but still maintain connections to it. The feeling of disconnection can be seen in various contexts, like when individuals leave prison or when they have different cultural values in their community. Authors like Jamaica Kincaid and Ralph Ellison explore notions of identity, freedom, and a longing for a sense of belonging, which are related to this experience.
