Accarezzami is the imperative form of the verb accarezzare, meaning 'to caress' or 'to stroke', combined with the direct object pronoun 'mi' (me).
In the song, the singer repeatedly asks his mother to 'accarezzami la testa' (caress my head) and 'accarezzami i capelli' (caress my hair). This word beautifully conveys a deep longing for comfort, reassurance, and the tender touch of a mother, highlighting a universal human need for solace in times of distress.
"Madre" is Gianluca Grignani singing directly to his mother in a moment of confusion and loneliness. He asks her to stroke his head and hair the way she did when he was little, and to tell him what has happened to him now that he suddenly feels lost and fatherless in the middle of the universe.
His hands are shaking and he admits the fear, but he insists he is strong and that she will see it. He looks back at a simple childhood memory, chasing the white trail of an airplane across the Milan sky with his hand.
The song moves between that childhood tenderness and his adult fear, circling back each time to the same word: Madre. It ends there too, repeating "Madre" as a plea more than a statement.
