Mein Ein und Alles
/maɪn aɪn ʊnt ˈaləs/
My everything
Literal translation
my one and all
When to use it
Heavy, sincere — usually reserved for partners or kids. You'd write this in a card, not say it in passing.
In conversation
—Du bist mein Ein und Alles, das weißt du.
“—You're my everything, you know that.”
