Inquebrantable translates to "unbreakable" or "unwavering". It's a strong and less common adjective that conveys deep resilience and steadfastness.
In "Te Quiero Así," the singer uses it to describe the partner's "inquebrantable lealtad" (unbreakable loyalty). This highlights a profound and enduring quality of their love, making it a powerful and memorable word in the context of the song's theme of enduring affection despite past mistakes.
Amistades Peligrosas's "Te quiero así" is a heartfelt declaration of love, but it's not your typical romantic ballad. Instead of listing all the wonderful things about his partner, the singer starts by apologizing for past mistakes. He sings, "por esos años que no supe amar, por esos meses que te hice llorar" [for those years I didn't know how to love, for those months I made you cry], acknowledging his shortcomings and the pain he caused. It's a surprisingly honest and vulnerable way to express affection, focusing on gratitude for his partner's patience and loyalty despite his flaws.
The song continues with more confessions, like "porque yo nunca te lleve a bailar" [because I never took you dancing] and admitting to "mi constancia por mi vanidad, por mi egoísmo" [my constancy for my vanity, for my egoism]. Despite all this, he reiterates, "te quiero así" [I love you like this]. He appreciates her "cariño y tu fertilidad" [affection and your fertility], her "apoyo y tu serenidad" [support and your serenity], and her "inquebrantable lealtad" [unbreakable loyalty]. It's a beautiful, if unconventional, way to say that he loves her completely, imperfections and all, and cherishes her unwavering presence in his life.
