Romeika, also known as Rhodian Turkish, is a unique linguistic phenomenon that emerged in the Greek island of Rhodes during the Ottoman Empire period. As a result of the cultural exchange between the Turkish and Greek populations, a distinct dialect was formed, which is still spoken today. This paper aims to introduce the Romeika Türkçe Sözlük, a comprehensive dictionary that documents the Romeika language, and discuss its significance in preserving the linguistic and cultural heritage of Turkey and Greece.
