Renacer means "to be reborn" or "to be born again." It's a powerful and hopeful verb that stands out amidst the song's themes of loss and emptiness.
In the context of "Después De Ti," Alejandro Lerner sings, "Sé que voy a renacer" (I know that I will be reborn). This word signifies a profound transformation and the promise of new beginnings after a significant heartbreak, making it a very evocative and memorable choice.
Después De Ti is Alejandro Lerner's meditation on moving forward after heartbreak. He opens by refusing regret — "Yo no me arrepiento" ("I don't regret it") — even for "los sueños derramados" ("the spilled dreams") and the sleepless nights love cost him. The chorus turns the loss into near-total absence: "Después de ti ya no hay nada" ("After you there's nothing left"), just "un recuerdo perdido" ("a lost memory"). But the song does not stay in despair. Lerner compares heartbreak to weather nobody questions — "Cuando el cielo llora, nunca nadie le pregunta dónde duele" ("When the sky cries, no one ever asks it where it hurts") — and commits to healing anyway: "Dejaré que el tiempo cure todas las heridas" ("I'll let time heal every wound"), certain he'll "renacer" ("be reborn") once the ache passes.
