What is greek for heart and soul?

There isn't a single, perfect Greek phrase that directly translates to "heart and soul." The best translation depends on the nuance you want to convey. Here are a few options:

* Ψυχή και καρδιά (Psychí kai kardiá): This is a literal translation, using "ψυχή" (psychí) for soul and "καρδιά" (kardiá) for heart. It's straightforward and understandable.

* Από καρδιάς και ψυχής (Apó kardiás kai psychís): This translates to "from the heart and soul," emphasizing the origin of a feeling or action.

* Με όλη μου την καρδιά και την ψυχή (Me óli mou tin kardiá kai tin psychí): This means "with all my heart and soul," conveying complete dedication or commitment.

The best choice depends on the context. If you're just naming a concept, ψυχή και καρδιά is sufficient. If you want to emphasize the intensity or origin, the other options are better.
