sizlere ömür! = He is dead; she is dead;
he passed away, she passed away.

-Why do they use sizlere to mean he,or she?-

Thank you for yur explanation

It is said when someone is dead.It means " he/she is dead,i pray God gives life to you!" "Omur" means "life".

That means,
sizlere ömür!

Siz + ler + e

Sizler,is plural of siz, doğru mu ?

Well,my understanding is, siz in this case i don't think its plural,siz here is singular,but for addressing old people,or for formal talk,
So,sizler,is just addressing more than one person formally,
Right ?!

Hi,
This is an idiom. It means "he/she passed away". It will be misleading if you are trying to translate idioms word by word.

But,isn't sizler the plural of the formal siz ? or am i wrong ?

Yes, it is but the literal meaning of an idiom is not important.

When you had said "hit the sack" and I would start asking you about hitting sacks and why people are hitting them or how they are hitting them, it would not make sense. You accept idioms as they are. But yes, this one has a hidden meaning:

(Allah) "Sizlere ömür" (versin): (May God give a long life 'to you', but he didn't give to him and) "he passed away".

The hidden part I have put inside paranthesis. Sizlere refers to "to you" in that hidden part.

Ahh,ha,annladım,çok tşk,
Bu arada,Cumhuriyet Bayramı kutlu olsun !

İ hope i said it right ,and thx for the info.
