When immigrants adopt some aspects of the local culture while keeping aspects of their culture of origin, this process is called .

creolization

Explanation:

Creolization is most commonly referred to the languages that merged with the dominant language and culture to produce a new language with variations and an own life:

The cases most exemplified are the French variations that are present in Haiti (Haitian Creole, or in Mauritania, where Mauritian Creole formed).

The cultural patterns embrace selectively some aspects of European and Latin American or African origins as the people came in contact with each other.

The ethnic and social differences in this highly diversified societies account for the formation of a new culture with both local and external roots.
