usage
Δεν είναι μόνο ..., αλλά ...
This pattern is used to show contrast or emphasis: one thing is not the only important thing, and another idea follows. Put a noun or phrase after "δεν είναι μόνο" and another phrase after "αλλά". You can reuse it whenever you want to say that there is more than one important part. Example: "Δεν είναι μόνο τα δώρα, αλλά η αγάπη και η χαρά." = "It's not only the gifts, but the love and joy."
Δεν είναι μόνο τα δώρα, αλλά η αγάπη και η χαρά.
It's not only the gifts, but the love and joy.
