Ingenua translates to "naive" or "innocent." It's a poignant word that captures a key emotional state in the song, reflecting on past mistakes and vulnerability.
In "Mi Peor Error," Alejandra Guzmán uses ingenua to describe her past self, singing, "Si fui ingenua al pensar que amarías igual" (If I was naive to think you would love the same). This word perfectly encapsulates the regret and self-reflection central to the song's theme of a love gone wrong, making it both relatable and impactful.
"Mi Peor Error" is Alejandra Guzmán looking back at a relationship she now sees clearly was doomed from the start, and admitting her own part in it.
She describes giving herself completely, believing the love would last forever, only to realize she was naive. She takes responsibility for lowering her guard and loving too hard, even though what she got back was false affection and empty words.
The chorus is the heart of the song: she still loves him, even knowing he was the worst mistake of her life. It's a song about the pain of loving someone who wasn't worth it, and the honesty it takes to admit that to yourself.
