The dictionary allows you to see how anthroponyms (proper names relating to people) can turn out to be names of objects, phenomena, geographical objects, etc. Contains 300 stories of the origin of names: biographies of people and descriptions of names (derived from the names of these people), which are used in many areas today's life. The dictionary is intended for high school students and students, teachers, journalists, as well as for everyone who needs to correctly understand and use various names and foreign words in speech.
