The papers featured in Issue 2/2021 of the Journal deal with major topics in the theory and practice of lexicography – both in a contemporary and historical perspective. The authors address problems of onomastic lexicography, neography, explanatory lexicography and the history of Bulgarian dictionary crafting. One of the papers sheds light on some aspects of the lexicographic practice in Poland. The issue is dedicated to one of the most eminent representatives of contemporary Bulgarian academic lexicography – Prof. DSc Maria Choroleeva – on the occasion of her forthcoming jubilee. Boris Parashkevov’s paper outlines a project for the creation of a dictionary of Bulgarian surnames. The concept of the dictionary envisages the organisation of family names in nests based on semantic equivalence (correspondence), associative reference and shared structural membership, thus making it possible to reveal the structural and semantic relations among the names under study. In addition, the dictionary entries document the derivational paradigm of the respective surnames, including short forms, diminutives and suffixal derivatives. Sia Kolkovska addresses some peculiarities in the lexicographic description of Bulgarian neologisms motivated by specific types of polysemy and synonymy. The author comments on the lexicographic description of the semantic structure of new polysemous loanwords and discusses the criteria for selecting a dominant synonym in synonym sets composed of neologisms. Diana Blagoeva and Sia Kolkovska’s paper also deals with issues in neography. The authors discuss the views on the categorial nature of neologisms of the type бизнесцентър/бизнес център (business centre) in Bulgarian and comment on the reasons for the emergence and establishment of this type of lexemes in the language, while considering the dynamics of their functioning. The paper motivates the necessity for the application of a special approach to the lexicographic description of this type of neologisms. Tsvetelina Georgieva comments on Nayden Gerov’s understanding of the so-called „равнознаменаменователни речи“ and highlights the contribution of the renowned lexicographer of the National Revival and the Post-liberation period to the representation of such names in an explanatory dictionary. The author maintains that these names should be considered not synonyms but heteroyms as they belong to different dialects. Nadezhda Kostova also takes a look at the history of Bulgarian lexicography in her discussion on the arrangement of dictionary entries in different types of dictionaries from the beginning of the 20th century. The author provides a comparative analysis of the peculiarities in the application of the alphabetical-nest arrangement in the lexicographic works under discussion. In his paper Petar Sotirov studies the application of the qualifier colloquially (potoczne) in Polish explanatory lexicography, taking as a point of departure the views on the notion of colloquialism in Polish linguistics. The author concludes that the dominant notion of colloquialism in Polish lexicography is the stylistic one and goes on to identify certain cases of inconsistencies and discrepancies in the use of the qualifier. Mihaela Kuzmova discusses the place of precedent phenomena (in par-ticular, the so-called “winged words”) in phraseology. The author proposes an analysis of several popular expressions of domestic precedent origin which have neither been described in lexicographic works, nor commented in the linguistic literature, and offers some observations on their phraseologisation and usualisation.
