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," Bruno Mars lays out a list of incredibly grand promises for the person he loves. He's not just offering dinner and a movie; he's willing to do literally anything. He says he'll give them "La estrella más lejana" (The most distant star) and if they ask for the moon, his response is "Yo aprendo a volar" (I'll learn to fly). The whole song is a series of these huge, dramatic declarations.
He seems to know how wild he sounds, admitting "Es loco, pero sí / Yo te quiero así" (It's crazy, but yes / I love you like this). He promises to walk on fire, climb any mountain, and even cross the entire sea just for a hug. The title says it all: "Lo arriesgo todo por ti" (I risk it all for you). It's a song about a passionate, all-or-nothing kind of love where no challenge is too great.
