The author describes the notion of phraseological competences and presents the results of her diagnostic study conducted among students of Applied Linguistics: French and Romance Studies at the University of Silesia in Katowice over three subsequent academic years. The aim of the diagnosis was to investigate the development of phraseological competences at a more advanced level of command of a foreign language. The results served also the purpose of analysing the relationship between comprehension and acquisition of phraseologisms in a foreign language and the level of their idiomatisation or phraseological consolidation.
