‚Nadryw‘ is a russian word that stands for strong emotional tension. Originally used to describe the transformation of a material structure under the influence of a mechanical force, it has additionally been used to express a strong psychic tension. Particularly this second connotation – that of a specific, extreme state of mind – has been attributed to the term since Dostojewski. It increasingly appears as a synonym for ‚psychosis‘, although among literary scholars, this word is considered untranslatable. (from: Wikipedia, the free encyclopedia)
