In this book, common words of the English language are recorded, organized in the form of alphabetically listed entries, which demonstrate the influence that Ancient Greek had on it. Additionally, the etymological origin and semantic evolution of the words are presented concisely, as well as the path they followed, often through Latin or other European languages, until their incorporation into English. The book highlights the importance of the Greek language in the creation of neologisms, which later passed as borrowings into Modern Greek. These words constitute an indicative and enlightening sample of the deep imprint that Ancient Greek has left on the English language, the contemporary lingua franca, not only within the framework of the Sciences, which are full of neologisms that consist of Greek word composition, but also in everyday vocabulary.
