Synonymy, a guideline for distinguishing synonymous words in a language during their usage, deals with words that either modify the same main concept through different qualifiers, denote objects of the same kind while distinguishing individual categories, or represent concepts that, although inherently different, are closely related due to the similarity of their content and can easily be confused in common discourse. In the Latin language, synonymous words are frequently used both individually and side by side, and a thorough understanding of them is essential not only for those explaining Roman authors but also for anyone expressing their own thoughts in this language.

The Publishing House of Sciences publishes historical literature by both well-known and lesser-known scientific authors. This makes previously out-of-print works accessible again to interested readers.

This book on Latin synonymy, based on Gardin-Dumesnil's 'Synonymes Latins', is an unaltered, high-quality reprint of the original edition from 1833.
