Apodera comes from the verb apoderarse, which means 'to take possession of' or 'to seize'. It's a much more dramatic and powerful word than simply 'to take', deriving from the word poder (power).
In this passionate song, the singer describes how seeing her lover makes her feel: "Se apodera de mi cuerpo, de mi alma y mi cabeza" (He takes over my body, my soul, and my head). She's describing a total surrender, a feeling so strong it seizes complete control of her being, making this a very memorable and intense word to learn.
This song tells a story of a secret, thrilling romance. It's about a woman who feels completely transformed when she's with a certain man. The lyrics switch between describing her feelings from the outside and hearing from her directly. When she's with him, she says, "yo me siento otra persona" (I feel like another person) and feels so happy that "nada temo, nada importa" (I fear nothing, nothing matters).
This isn't a simple love story, though. She knows this relationship has an expiration date, calling it her "cuento de hadas" (fairy tale) that she knows "tiene fin" (has an end). There's a hint of an age difference and regret when she wonders what she would do if she had "veinte años menos" (twenty years less). The biggest twist is that he knows the truth: "Que en su vida hay alguien más" (That in her life there is someone else). It seems she is the one with another partner, making this a passionate and complicated affair.
