Asombres comes from the verb asombrar, meaning "to surprise" or "to astonish." It's an interesting word because it's not as common as other verbs for surprise, like sorprender.
In the song, the singer begins by saying, "No te asombres si te digo lo que fuiste" (Don't be surprised if I tell you what you were). This sets a dramatic tone, implying that the truth about the person's past actions might be shocking or unexpected, making asombres a key word in establishing the song's emotional depth.
Get ready to feel some serious heartbreak with Grupo 5's "Amor de Mis Amores"! This song is all about a love gone wrong, where the singer is reeling from a betrayal. He can't believe how ungrateful his former lover was, especially after he adored her so tenderly. He sings, "No te asombres si te digo lo que fuiste, Una ingrata con mi pobre corazón" [Don't be surprised if I tell you what you were, an ungrateful woman to my poor heart], because her beautiful dark eyes led him down the path to another love.
Even though he's clearly devastated, he's also trying to save face. He doesn't want anyone to know how much he's hurting, asking, "¿Qué gano con decir que otra mujer cambió mi suerte? Te burlaras de mí, que nadie sepa mi sufrir" [What do I gain by saying another woman changed my luck? You'll make fun of me, let no one know my suffering]. It's a relatable feeling of wanting to keep your pain private, even when your heart is shattered. He's so hurt that he vows, "Lo que conseguirás, que no te nombre nunca más" [What you'll achieve is that I'll never name you again]. Talk about a dramatic exit!
