What is meant by assimilation in the context of cultural adaptation?

In the context of cultural adaptation, the correct understanding of assimilation refers to fully abandoning one's original culture in favor of the new culture. This process involves individuals or groups adopting the external behaviors, values, and practices of the dominant culture, often at the expense of their original cultural identity. As they assimilate, they may cease to use their native language, follow traditional customs, or participate in unique cultural celebrations, thus becoming more like the prevailing social group.

This process is distinct from other approaches to cultural adaptation, such as integration or multiculturalism, which emphasize the coexistence of multiple cultures and the retention of original cultural practices alongside the new cultural influences. Such contrast helps to clarify why the other options reflect different aspects of cultural adaptation that do not fit the singular definition of assimilation.
