Question

What is the meaning of assimilation?

Answer 1

Turning someone/thing into an identical copy of another. For instance, assimilating with Japanese culture is trying to follow it as if you were Japanese. (if that made any sense.)

Answer 2

It's when a person or a group of person try to integrate themselves into another group, by learning and applying their traditions, cultures, way of speaking, slangs, etc...
For example, the Immigrants in the us try to assimilate themselves in the American culture.

Hope this Helps! :)
