Assimilation is the process by which individuals or groups adopt the cultural traits of another group, often leading to a loss of their original identity. This can occur when immigrants or minority groups integrate into a dominant culture, adopting its language, customs, and social norms. The process of assimilation can be voluntary or forced, and it often involves changes in lifestyle, values, and beliefs. For example, immigrants may learn the language of their new country and participate in its traditions, which can help them fit in but may also result in the erosion of their original cultural practices.
