Cicatrice translates to "scar". It's a poignant and evocative word that immediately brings to mind lasting marks left by past experiences.
In the song, Francesco Renga uses "cicatrice" to represent the emotional wounds and unspoken truths that remain deep within a person, affecting their heart and creating new pains. He sings, "tra l'anima e la superficie, la cicatrice quello che non si dice" (between the soul and the surface, the scar is what isn't said), highlighting the hidden impact of these emotional marks.
Francesco Renga sings about two people who know each other too well to stay apart and too well to stay together. "Siamo simili" ("We're similar") opens the song on that closeness — same limits, same steps, same old scars — but by the chorus the only way out he can find is forgetting: "Vorrei solamente cancellarti per sempre" ("I just want to erase you forever").
It never lasts. Two lines later he's back in it: "Ma tu sciogli i pensieri e leghi le mani, allora mi ami" ("But you unravel my thoughts and tie my hands, so you love me") — the whole plan collapses the moment she touches him. The song runs on that loop, wanting her gone and wanting her close in the same breath, and it closes exactly where it started: "Ma è tardi domani" ("But tomorrow's too late").
