Incondicional translates to "unconditional." It's a strong and profound adjective that describes something without limits or conditions.
In this song, Sen Senra uses it to declare his love as "mi amor Incondicional" (my unconditional love). It perfectly encapsulates the enduring and selfless nature of his feelings, making it a powerful and memorable word that defines the core message of the song.
Sen Senra's "Incondicional" is a really heartfelt song about a love that remains strong even after a breakup. He sings about how, even when his partner no longer felt anything, he still loved them just as much as he does today. When they left, he watched them go and says he "Solo pude darle las gracias a Dios" [could only thank God] for having truly felt and given his all to the relationship. It's a sweet, almost nostalgic look back at a past love.
Even though they're no longer together, he's still wishing them well, asking that no one hurts them and that no one treats them better than he did. He hopes he doesn't become a stranger to them and that they keep him in their heart, even if it's just a tiny space in a corner. He admits, "No le hagas caso a mi rebeldía" [Don't pay attention to my rebelliousness], because for him, she "fuiste y serás mi amor Incondicional" [were and will be my unconditional love]. It's a beautiful, honest declaration of enduring affection.
