The fourth volume of the fundamental multi-volume dictionary is a systematic description of the vocabulary of the Church Slavonic language of the New Age (letters G, S, Z). It will be indispensable when reading biblical, liturgical, hagiographic and other Church Slavonic texts. The main task of the dictionary is to serve as a source of information about the meanings of Church Slavonic words and expressions. At the same time, some grammatical information is given for each word, with meanings, if necessary, encyclopedic information is given, and Greek parallels are brought to illustrations from Church Slavonic texts.
