The fifteenth volume of the Dictionary of the Bulgarian Language, prepared by the staff of the Section for Bulgarian Lexicology and Lexicography at the Institute of the Bulgarian Language "Prof. Lyubomer Andreychin" at the Bulgarian Academy of Sciences, contains 6543 dictionary entries of words starting with the letter R. The vocabulary of this volume of the Dictionary is primarily verbal. This includes numerous non-derivative verbs and derived verb lexemes formed from them through various word-formation means, through which various semantic and stylistic nuances are expressed. A significant place in the dictionary of the volume is occupied by derived verbs formed with the prefix раз-, one of the most productive prefixes in the language from the early stages of its development to the present day. This part of the dictionary once again presents the great verbal wealth of the Bulgarian language.
