The study of proper names translation in folklore is characterized by interdisciplinary approach. Nowadays there are a lot of studies aimed to classify and organize all the possible variants of proper names translation. And, despite the diversity of these works, one can observe the extraordinary variability in this field. PN in folklore, especially in a fairy tale are the most important keepers of information. They contain the most important implicit information and reveal cultural values and traditions of every nation. A deep analysis of PN in synchrony and diachrony predetermines a successful adequate translation as well as knowledge of target audience and choice of culture-oriented strategies.
