Etymology

Origin of assimilate

First recorded in 1570–80; from Latin assimilātus “likened to, made like” (past participle of assimilāre ), equivalent to as- as- + simil- ( similar ) + -ātus -ate ¹

Explanation

If you are trying to fit in, you are trying to assimilate. Imported from Latin, assimilate has the word similar within it and in fact, means "to become like something else." If someone moves to another country, he or she will need to assimilate by adapting to and taking in the language, culture and customs of the new place. You can also turn the phrase around to say that a country assimilates immigrants, which means that a place accepts immigrants and allows them to adapt easily. In scientific use, the body assimilates nutrients as a part of digestion.
