Abstract
This paper is a conceptual supplement sui generis, the aim of which is to present a modified treatment of proper names and deproprial expressions in the Academic Dictionary of Contemporary Czech (ADCC). The focus of the study is both a reflection on the past and current lexicographical practice and a discussion of the key issues related to the treatment of the respective lexical subsystem in the dictionary. First, we summarize the basic facts concerning the lexicographic processing of proprial and deproprial lexical units in the field of explanatory lexicography. Second, we provide some more general information about the ADCC and, most importantly, about the macrostructure and microstructure of the dictionary in reference to the topic of the present study. We focus on the inclusion of proprial and deproprial entries in the ADCC and the specific treatment of proper names contained in phrasemes. Special attention is paid to the microstructure of proprial and deproprial entries, as well.
