I would like to share my mother tongue knowledge with anyone who wants to learn it

Perfect! Zafeiro is an excellent teacher. I take Greek lessons with her, and she adapts the lessons for my knowledge status and individual needs (not to mention that she is a very nice person and it is just fun working with her!)
She trains me with useful phrases and expressions in conversations, while blending in some grammar at the same time, and when needed, extra pronunciation training. If needed, she gives detailed instructions how to form this exact sound with your lips/tongue/teeth, showing you how to produce this sound. This helps so much in getting a good pronunciation, in my opinion!
Although I am still a beginner with only little pieces, I feel that I jump right into conversations, and expanding my knowledge of the Greek language easily and quite quickly.
Just a 5-star rating for this teacher!

Perfect! Mit Zafeiro habe ich wunderbare Erfahrungen gesammelt. Sie ist eine sehr gute Lehrerin und dank Ihr habe ich mich in meinem Griechenland Urlaub zurecht gefunden. Wer Griechisch lernen möchte, ist bei Ihr perfekt aufgehoben.
