Maré vento literally translates to "tide wind." It's an interesting and somewhat poetic phrase that isn't commonly found in everyday Portuguese songs.
In the context of the lyrics, "Dizem que planos feito Maré vento" (They say that plans are like tide wind), it suggests that plans are unpredictable and easily changed or carried away, much like the shifting tides and winds. This metaphorical use makes it a memorable and thought-provoking phrase.
In "Se Fores Embora," which translates to "If You Go Away," CEF Tanzy sings a passionate and desperate plea to a lover. The song explores a love so intense that the singer feels they simply cannot live without their partner. He worries about what will happen if they leave, singing, "se você for embora / todo mundo vai ser riso mim," which means "if you go away / everyone will laugh at me."
This isn't just a private fear. The singer has made their feelings public, telling everyone, "sem você não vivo" ("without you I don't live"). This public declaration makes the thought of a breakup even more painful, as he fears not just heartbreak but also public shame. The song is a raw expression of vulnerability, dependency, and the all-consuming nature of a powerful love.
