Перевод - Греческий-Турецкий - Μοναδικό μου αστέρι είσαι η λάμψη της ζωής μου:

Asıl anlamı doğru, ama şekli biraz farklı:

Biricik yıldızım, hayatımın ışığısın.

Sen benim biricik yıldızımsın,hayatımın parıltısı

I don't know greek but the english version says :
biricik yıldızımsın,hayatımın parıltısın

I'll edit your translation according to the English one and accept that way idenisenko, this is the English translation:
"You are my unique star, the brightness of my life:"

this is the page with the English tranlation

λάμψη is not ışık !

maybe > biricik yıldızım, hayatımın ışıltısısın

>> my unique star, you are the shining(?) of my life

...and not brightness...

OK idenisenko, I think we need Greek expert's opinion now

Hello Irini! Could you please tell us that if the Greek text says "You are my unique star, the brightness of my life"? and if the "brightness" for "λάμψη" is correct

CC: irini

Well, the way it is phrased I would translate it as "My unique star, you are the brightness of my life" . I'd say that "brightness" is fine.

Thanks irini! Yes it would be better if it was translated that way

maybe I should edit it as "pırıltısısın" instead "ışığı" idenisenko, do you think would it be okey?

no, "ışıltısısın" is better I think
