In “A Greek-English Lexicon of the Septuagint” when a word appears to be proper to the LXX and the literature depending on it, it is characterized as a neologism. The label “neol.” suggests that the word in question was probably not used before the time of the composition of the LXX. According to the Lexicon the first use of more than 500 words is in the Pentateuch. The purpose of the article is to trace how the Slavonic translator of the biblical books understands and transmits these words. It can be said that the translation of the neologisms is very indicative of the ways in which the vocabulary of the still young OCS was formed. It reveals the Slavonic men of letters not only as translators but as creators of the language.
