Arrepiento comes from the verb arrepentirse, meaning "to regret" or "to repent". It's a strong emotional word that conveys deep remorse or a change of heart.
In "Si Una Vez," the singer powerfully declares, "Si una vez dije que te amaba, hoy me arrepiento" (If once I said I loved you, today I regret it). This word is central to the song's theme of moving on from a past love and regretting the emotions once felt, making it very impactful and memorable.
Have you ever given someone your all, only for them to treat you with total disrespect? That's exactly what Alicia Villarreal is singing about in "Si Una Vez"! She gave her love and more, putting herself at her lover's feet, but all she got back was scorn.
But don't feel too bad for her, because this isn't a sad song for long! She quickly realizes her mistake, singing, "Si una vez dije que te amaba, hoy me arrepiento" [If I once said I loved you, today I regret it]. She even admits she "estaba loca" [was crazy] to have ever loved him. Now, she's done with that error and she's not going back! It's a fantastic song about taking back your power after a bad breakup.
