Excellent book for learning the language without a teacher. It covers a wide range. Vocabulary, grammar, expressions, and exercises. The structure aims to develop you progressively. It is also absolutely understandable in explaining particularly the grammar phenomena.

As a self-taught learner, with this book combined with selective channels on YouTube plus Duolingo, I am currently satisfied.

Tip1. for self-taught learners:
Include children's cartoons in the language you are learning in your routine. At first, you won't understand anything. Gradually, you will recognize words and their meanings without even being taught them.

Tip2. Find a partner. There are sites where you can find people whose native language is the one you want to learn and who also want to learn Greek.

Excellent book. I recommend it. The difficulty increases gradually. There are exercises with solutions. Basic vocabulary. Sentences. Text with translation. Grammar.

Very good introduction to the language. I recommend it.
It helps a lot to integrate into the language from the beginning, from the alphabet through vocabulary, grammar, and expressions. A very worthwhile choice.
