 The study of the Hungarian language is one of the main sources of the research on the ethnogenesis of the Hungarian people because a language shows the circumstances of its own development and its contacts with other idioms . According to a scholarly theory , the oldest layers of Hungarian vocabulary show features of the territory in which the language emerged . The study of loan words from other languages is instrumental in determining direct contacts between the ancient speakers of the Hungarian language and other peoples . Loan words also reflect changes in the way of life of the Magyars .
