The purpose of this paper is to work out criteria for selection of Russian conjunctions for the Swedish-Russian and Russian-Swedish dictionary Mini+ and to suggest a list of conjunctions to be included in it. The present study aims at collecting information, classifying it and examining Russian conjunctions in present-day Russian. The study also systemizes gathered material according to its diachronic features and makes corpus-based co-occurrence analysis, using Russian National Corpus (RNC) and Google Scholar. The paper presents a list of conjunctions to be included into the Russian part of the lexicon, based primarily on their grammatical and stylistic criteria as well as the results of the corpus-based frequency analysis. The choice takes into consideration limitations in size of the given dictionary. Out of a total 272 conjunctions, 55 were chosen for the Russian Swedish Mini+ dictionary. The major group (35) is simple conjunctions that frequently occur in corpus-based search and that are necessary to build basic grammar structures as well as other compound conjunctions, ex. а, даже, едва, если, чтобы, хотя. The second group (13) is compound conjunctions that are important for building most frequent subordinate clauses. The third group (7) is compound conjunctions that frequently occur in corpora.
