The phenomenon of «repentance» has been analyzed from the perspective of various sciences: communicative linguistics, linguocognitology, genristics, theolinguistics. Repentance is a genuine recognition of the fault, error, sin, regret at the offense. This understanding is related to a domestic repentance – a strong emotional experience, which is correlated with a sense of shame for him/herself and his/her actions (a secular approach to this phenomenon). In the spotlight is the intersection of the repentance concept with the repentance genre and dialogue.
