How do you say your my everything in greek?

There isn't one single perfect translation for "You're my everything" in Greek, as the best choice depends on the nuance you want to convey. Here are a few options, with slightly different connotations:

* Είσαι τα πάντα για μένα (Eisai ta panta gia mena): This is a very literal translation and a common and widely understood way to say it. It means "You are everything for me."

* Είσαι ολόκληρος ο κόσμος μου (Eisai olokliros o kosmos mou): This translates to "You are my whole world." This is a more romantic and emphatic way of expressing the sentiment.

* Δεν μπορώ να ζήσω χωρίς εσένα (Den borō na zīsō chōris esena): This translates to "I can't live without you." This is a very strong and passionate statement, implying a deep dependence. While it conveys the sentiment, it's not a direct translation of "you're my everything".

The best option depends on the context and your relationship with the person. For most situations, Είσαι τα πάντα για μένα (Eisai ta panta gia mena) is a safe and accurate choice.
