Language is a unique tool that helps people to investigate a surrounding reality and express their feelings, emotions, and attitudes. At the same time, it apparently impacts the environment as a person sees the world through the prism of his/her mother language (Mio, Barker, & Rodriquez, 2015). It has formed under the impact of unique phenomena peculiar to the area and important to the population living there. That is why we now can observe significant differences in mentalities and words that could not be translated into other languages because of the absence of the corresponding concept. In such a way, learning a new language, we acquire specific information about how individuals living in other countries think and behave.
For this reason, our mother language starts to interact with this new one. Some say that the language of origin becomes replaced by new words and concepts that appear in the course of study. However, there is another point of view assuming that both languages interact and result in the appearance of some new confluence. I believe that this idea is more reasonable. For instance, I know several languages, and there is no replacement or extrusion. On the contrary, knowing some unusual concepts and being able to use foreign words, I also can think and analyze the world from another perspective. At the same time, the second language helps to understand the environment better. Communicating with individuals from different countries, I can use combined knowledge gained from several languages. In other words, I believe that they interact and promote a significant increase in cognitive abilities and alterations in the mentality that help to communicate with people and understand the world better.
