It further attempts to conceive the basic structural modifications of lie on the basis of the linguistic markers typical to this phenomenon in Russian and Bulgarian linguoculture. The classification of the linguistic exponents of the phenomenon forms the communicative behavior of the sender with respect to the realization of his/her communicative intention. The paper also discusses its variants such as slander, appraisal, compliment, disorientation, mystification and others. Specific national stereotypes in the interpretation of the phenomenon are also presented in the article.
