Arrendersi means "to surrender" or "to give up." It's a strong verb that carries a sense of resignation or acceptance, often in the face of overwhelming odds.
In "XI Comandamento," Vasco Rossi repeatedly uses this word, urging listeners to "conviene arrendersi" (it's convenient/better to surrender) to evidence, distance, ignorance, and arrogance. It's a provocative and thought-provoking choice, suggesting that sometimes the wisest course of action is to accept what cannot be changed, rather than fighting endlessly.
"XI Comandamento" imagines an eleventh commandment on top of the traditional ten: simply give in to what you cannot change. Vasco Rossi repeats short, blunt phrases — you have to surrender, you can't argue with it, you have to notice the distance, the power, the ignorance around you — as if reciting a new rule of life.
Rather than sounding defeated, the song turns that surrender into momentum. "Avanti il prossimo" (bring on the next) and "avanti il popolo del cambiamento" (onward, people of change) push the mood from resignation toward acceptance and forward motion. The eleventh commandment isn't giving up — it's letting go of what's already decided so you can keep moving.
