The author of the paper aims at providing a description of lexical units containing the segment 'odkryc' with respect to their structure and meaning. The method of analysis is based on putting forward hypotheses in the form of analytical implications and subjecting them to falsification by bringing them down to contradiction. The content of the paper focuses on issues relating to reconstruction of the form of lexical units (on the basis of segment and supra-segment signals) and reconstruction of the hierarchy of meaningful components. In close relationship with the content of the analyzed terms, discussion is presented on the following notions: 'zrobic cos', 'wynikac' and 'wiedziec'. The author tries to prove that those components belong to the semantic structure of the examined phrase; he also proposes a preliminary explication of meanings in the terms of natural semantic meta-language.
