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 incomplete: behind it must come the person you wish that health to. 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 incomplete: behind it must come the person you wish that health to.

Γεια σου (ya su) — "your health" in the singular: to friends, peers, children. Γεια σας (ya sas) — "your health" in the plural, and σας (sas) covers two cases at once, several people and the polite "you", exactly as English "you" does. With a stranger and with an elder there is only one choice: Γεια σας.

The same word says goodbye: Greek keeps no separate "bye", so Γεια σου sounds both at the meeting and at the door. And it does not sound the way it is written: before ε and ι the γ turns almost into a y, and the two greetings come out "ya su" and "ya sas".

A rule is not memorized from an explanation. It is memorized from an attempt to use it and a mistake — that is why the app delivers it mixed in with words, not as a separate lesson: it resurfaces exactly where you forgot it.
