Humille comes from the verb humillar, meaning 'to humble' or 'to humiliate'. It's an interesting word because it conveys a strong sense of vulnerability and desperation.
In the song, the singer's heart is pleading for love, and he sings, "No te importa que me humille si eso estás pensando" (You don't care if I humble myself if that's what you're thinking). This line reveals the depth of his unrequited love, where he's willing to debase himself just for a little affection, making it a poignant and memorable word.
Vicente Fernández brings us a song about a man absolutely fed up with his own heart! He's heartbroken because the person he loves doesn't love him back. He sings, "Quiere el corazón lo quieras como yo te quiero" [My heart wants you to love it like I love you], begging for just a little affection. He even says, "No te importa que me humille si eso estás pensando" [You don't care if I humiliate myself if that's what you're thinking], showing how desperate he is for this love.
But then, the song takes a turn! His heart just won't give up, even though the person has clearly said no. He's so frustrated with his persistent heart that he cries out, "Ay corazón, ya no insistas me partes el alma" [Oh heart, don't insist anymore, you're breaking my soul] and even, "Si no entiendes, ¿por qué no te callas?" [If you don't understand, why don't you shut up?]. It's a really relatable feeling when your emotions just won't listen to reason, and Vicente Fernández delivers it with all the passion you'd expect from a ranchera legend.
