Inganno translates to "deception" or "trick". It's a word that carries a strong emotional weight and suggests betrayal or a misleading situation.
In the song, Giusy Ferreri sings, "Il tuo futuro non sia un inganno" (May your future not be a deception). She's expressing a deep wish for her loved one's future to be free from lies and heartbreak, making it a poignant and memorable word in the context of a romantic relationship.
Giusy Ferreri turns an invitation into an act of forgiveness. She promises to leave someone's past outside the door — "Il tuo passato non è invitato" [Your past is not invited] — and admits she's earned some of the blame herself: "Se me lo sono un po' meritato" [If I somewhat deserved it]. The dinner stands in for everything she never said, like the letter she never got around to writing: "Avrei voluto scriverti una lettera" [I would have liked to write you a letter]. Underneath the invitation is a truer confession — the smile hides how much of "the best" already left with him: "Il meglio è andato via con te" [The best has gone with you]. By the closing "Via con te" [Gone with you], the dinner she offered has quietly become a goodbye.
