#Yia_Sou

Possibly the most essential Greek phrase, and one of the most common Greek greetings, ‘yia sou’ is an informal way of saying ‘hello’. What your Greek phrasebook probably won’t tell you though, is that ‘yia’ is a shortening for ‘iyia’ which means ‘health’ in Greek –
i.e. you greet people by literally wishing them good health (isn’t that the sweetest?).
