However, only the primary meanings correspond, the derived meanings in Latvian are related to the expression of the emotion kauns (shame), while the meaning transfer is more indirect and detached.In respect of their semantic structures, the lexemes denoting shame in Latvian and Lithuanian present even more differences: the denomination is more intricate in the Latvian language, though, semantically, the derived meanings are close to the primary meaning; in Lithuanian the lexeme has two meanings and the derived one manifests the marked transfer of meaning. In the analysis of denominations of emotions and their semantics, the intensity of the expression of feelings is of great significance as well.
