The article is devoted to the analysis of the semantic processes that occur within the phraseological units in the English and French linguistic pictures, regarding the antonymic relationship between the concepts of “success” and “unsuccess”. The aim of the article is to find both common and particular parametric components of English and French antonymic phraseologies and investigate the relationship between the phraseological units that build them up. The methods used for this research are those of general linguistics, but also those specific to cognitive linguistics. English and French are languages that have many differences from a structural and semantic point of view, and their phraseologies have not been investigated enough, let alone the relation of antonymy between the two concepts proposed.
