Bilingvismus a codeswitching

The thesis focuses on the issue of bilingualism and codeswitching. Bilingualism is a natural phenomenon of more than half of the world's population. The thesis discusses all the possible definitions of bilingualism and of bilingual people. It briefly deals with the history of language development within Europe and then continues to discuss the situation of language development in the European Union. Codeswitching is inseparably connected with bilingualism as it is the act of switching between one language to another. Also closely connected with bilingualism is intercultural communication for which the simple knowledge of grammatical rules is not enough. The thesis has adopted the results of different research which are predominantly focused on modern methods of measuring human brain activity. So the essential questions which are connected with language growth, receiving of information and the formation of language systems are answered. The thesis also puts emphasis on the possibility of the growth of bilingualism to which the reasons are most often influenced by the environment or the effort for the search of employment.
