In this paper we present the Modern Georgian – Modern Greek Dictionary of Idioms, a bilingual dictionary targeted at language learners and professional translators that has been compiled in the framework of a project for Young Scientists. After presenting the results of the project, we discuss the main methodological principles that underlie its construction and elaborate the main features of the dictionary. In particular, we report on the macrostructure (the organization of the headwords in word families and groups of derived words and compounds that highlights word production mechanisms) and the microstructure of the dictionary. The dictionary consists of 11801 entries of idioms.
