The book you hold in your hands was created with the aim of becoming a valuable guide for all of us on an exciting journey through the Greek language. It is divided into two parts. The first part contains the grammatical phenomena taught in all grades of Primary School. Each page contains essential information and examples for understanding and using Greek grammar in daily life, in language activities, and in written expression, which is the focus of the second part of the book. This part presents different types of texts along with their corresponding structures, that is, the steps that in a simple and clever way lead to the writing of complete texts. We hope that studying this book will pleasantly accompany our journey towards more effective use of the language.
