Armatura translates to "armor". It's an evocative word that immediately brings to mind images of protection and defense.
In the song, Tiziano Ferro sings, "Non è colpa tua se indosso sempre un'armatura" (It's not your fault if I always wear armor). He uses this metaphor to describe his emotional guardedness, suggesting he protects himself from vulnerability due to past experiences. This makes the word both interesting and relatable.
Twenty-five years after "Xdono" made him famous, Tiziano Ferro reopens the same apology and finds it still unfinished. The chorus is the one Italy has known since 2001, "Sì, quel che è fatto, è fatto io però chiedo scusa" ("Yes, what's done, is done, but I apologize"), and he points at the date himself: "Come Natale 2001" ("Like Christmas 2001"). Building a second hit out of the same request for forgiveness is a strange move, and the song knows it.
Then Lazza takes the beat and refuses the whole premise. "Chiedo scusa, ma non chiedo scusa" ("I apologize, but I don't apologize") is the hinge, and what follows is armour where Ferro offered a rose: "Non è colpa tua se indosso sempre un'armatura" ("It's not your fault I always wear armor"), then "Nel petto ho il vuoto, Chernobyl" ("I have emptiness in my chest, Chernobyl"), which is a bit much and lands anyway. Two men on one apology, only one of them willing to make it, meeting at the end on "E col perdono ci salveremo ancora" ("And with forgiveness we will be saved again").
