The aim the article is to study the model of coexistence of different languages in the multicultural environment of Ukraine and EU countries (the Czech Republic, Germany, Poland and Italy). Methods. Testing was conducted using the Communicative Attitudes Technique. The degree of satisfaction with the environment was studied. Statistical analysis was performed using t-test, the Kolmogorov-Smirnov test, Pearson’s correlation coefficient. Reliability analysis was performed using Cronbach’s alpha. Results. The adaptability of EU citizens was found to be significantly higher than that of the residents of Ukraine (t=13.24; p < 0.001). The indicators of EU citizens are higher than those of Ukrainians (p<0.001) on a number of qualitative characteristics of adaptability: self-acceptance (t=21.84), acceptance of others (t=4.01), emotional comfort (t=4.49), internal control (t=33.74), external control (t=8.12); consciousness (t=2.58 at p<0.05). Conclusions. The obtained results give grounds to state a high level of communicative tolerance in the multicultural environment. This indicates the existence of effective models of multilingualism both in Ukraine and in the EU countries. Prospects. Further research may focus on identifying universal languages as communicative tools both in Ukraine and in EU countries.
