Γεια σου and Γεια σας: to friends and to everyone else

The Greek greeting is the word γεια, "health", and on its own it is unfinished. Whoever the health is wished to has to follow. For example: “Γεια σου, τι κάνεις;” — Hi, how are you?. A rule from the Greek course: worked out on examples, not memorized as a wording.

How it works

The Greek greeting is the word γεια (ya), "health", and on its own it is unfinished. Whoever the health is wished to has to follow.

Γεια σου (ya su) — "your health", to a friend, a peer, a child. Γεια σας (ya sas) — the same for a stranger, for an elder, or for several people at once. English "you" covers both in one word; Greek does not.

The same word does the parting: there is no separate "bye". Γεια σου works on the way in and on the way out.

It is not read the way it is written. γ before ε and ι turns almost into a "y", so it comes out "ya su" and "ya sas".
