Arriesgo is the first-person conjugation of the verb arriesgar, which means "to risk". It's a powerful and dramatic word that perfectly captures the song's central theme.
In the title and key line, "Lo arriesgo todo por ti", Bruno Mars declares, "I risk it all for you." This single word elevates the song from a simple declaration of love to an epic promise of making grand, daring sacrifices. It's the ultimate expression of devotion and what makes this song so compelling.
In "Lo Arriesgo Todo" ("I Risk It All"), Bruno Mars takes romantic drama up to eleven. He goes all-in with grand, impossible promises to win someone over, openly admitting that his level of devotion is wild: "Es loco, pero sí" ("It's crazy, but yes"). If you ask for the moon, he claims "yo aprendo a volar" ("I will learn to fly"). Want the farthest star? "Te la doy" ("I'll give it to you"). He even promises to climb any mountain, cross an entire ocean for a hug ("Cruzaría todo el mar para abrazarte"), and walk across fire ("Sobre fuego caminar") just to be close.
Beyond the over-the-top stunts, he offers emotional support too, promising "Tu corazón herido / Yo puedo curar" ("Your wounded heart / I can heal"). The entire track hinges on absolute commitment, declaring "Quiero ser solo yo / El hombre de tu vida" ("I want to be the only one / The man of your life"). It is sweet, completely dramatic, and packed with direct, useful Spanish phrases for expressing devotion when simple words aren't enough.
