This book is the first one that deals with the teaching of Greek as a second/foreign language, offering a comprehensive overview of the subject. The basic methods of teaching foreign languages are presented, with an emphasis on the communicative method, and suggestions are made for structuring the lesson according to the age and needs of the students. In the chapters on pronunciation, nouns, adjectives and adverbs, verbs, and types of Greek sentences, the concepts and phenomena that pose difficulties for foreign students are analyzed, and simple and clear ways of presenting them are proposed. In the chapter on vocabulary, the modern trends in teaching vocabulary to foreigners are presented, along with their lexical errors in Greek, and methods for teaching synonyms, antonyms, derivatives, and compounds are suggested. The book is a valuable aid for students of Pedagogical and Philosophical Schools, teachers and professors who have foreign students in their classes, and of course for teachers of intercultural schools. It is also useful for teaching Greek to Roma and minority language students, as well as to children of Greek immigrants and repatriates.
