Arrepiento comes from the verb arrepentirse, meaning "to regret" or "to repent". It's a strong emotional word that conveys deep remorse.
In the song, the singer expresses profound regret, singing "aún ahora me arrepiento de todos los días en que aún estuve a tiempo para hacerte regresar" (even now I regret all the days when I was still in time to make you come back). This word captures the core theme of lost chances and lingering sorrow, making it very impactful.
Leonel Garcia's "Suficiente" is a really heartfelt song about a relationship that just couldn't make it, no matter how hard both people tried. He sings about doing "todo lo posible" [everything possible] and even "hasta lo imposible" [even the impossible] to save what they had. It's clear there was a lot of effort, with him seeing her "luchando con la vida entera" [fighting with her whole life] to keep them together.
But despite all that effort, it just wasn't enough. He describes losing days and seeing her "llorando noches" [crying nights], with "silencio" [silence] and no laughter in the car. The line "Pero no fue suficiente / El hilo ya estaba roto" [But it wasn't enough / The thread was already broken] really hits hard, showing that some things just can't be fixed. He admits to offering answers he didn't even believe himself, and trying to reach her, "dejando el alma en recuperarte" [leaving his soul in recovering you], but it was too late. It's a sad but honest look at when love isn't enough to overcome what's broken.
