Research at the Institute encompasses several aspects of the history of the Hungarian language. This includes the history of the language in the narrow sense; the systematic study of other Uralic languages; various forms of language contact and areal features; the study of the dialects of Hungarian; the systematic study of Latin, a language that had a great impact on the development of Hungarian. The Research Groups of the Institute work on the following projects: the historical phonology of Hungarian; the historical and comparative syntax of Hungarian and the other Uralic languages; variety in Middle Hungarian as a function of register; contact-related aspects of the structure and history of the Uralic languages; Uralic ethnolinguistics; the acoustic analysis of vowels in Hungarian dialects; temporal (diachronic) and spatial (dialectological) analysis of changes in the Late Latin period. Several of the Research Groups are also involved in the construction of linguistic databases.
