The article is an analytical review of some problems of dictionary codification of Luxembourg German Standard. The relevance of the study lies in the fact that the Luxembourg variety of German Standard, which differs in a number of distinctive features from other national varieties of the German language, is still poorly studied. Some aspects of the study of the German language in Luxembourg, the criteria of the standard in general and the features of the Luxembourg standard of the German language in particular are briefly described. The main part of the study is the analysis of current lexicographic sources that codify the specific features of the pronunciation, grammar, lexical and semantic norms of the Luxembourg Standard. The results of the analysis of lexicographic sources, which are descriptive codifiers of the German Standard in Luxembourg, are presented: a pronunciation dictionary of the Standard High German language, the project “Regional Variation in the Grammar of Standard German”, dictionaries of varieties of the German language. The structure and content of the dictionary of the Luxembourg standard for the German language [Sieburg, 2022] are considered in detail. This includes general information about the mega-, macro- and microstructure of the dictionary, the subject and variable characteristics of the codified vocabulary, the features of the structure and content of dictionary entries. As a result of the analysis, a conclusion is made about the development of the normalizing activity of the Luxembourg German Standard and about the recognizing of this standard, which has specific features at different levels of the language system.
