Guelra translates to "gill", the respiratory organ of fish. It's a very specific and evocative word that immediately connects to the song's central theme of being a "mulher peixe" (fish woman).
In the lyric "Sangue na guelra", it literally means "blood in the gill". This phrase is a powerful image of vitality and the raw, untamed nature of the protagonist, emphasizing her connection to the sea and her inherent strength as a fish-woman.
Have you ever felt like you had a secret, powerful side to you? In "Joana do Mar," which means "Joana of the Sea," the singer reveals her secret identity as a "mulher peixe" or "fish woman." This isn't just any fish, though. She's a magical, flying fish with shining scales, leaping through the air. This powerful image represents a woman who is breaking free from expectations and fears.
She declares, "Eu decido / O meu enredo" ("I decide / My plot"), taking full control of her life's story. The song is a celebration of self-discovery and embracing one's true nature. With a fierce spirit like "sangue na guelra" ("blood in the gill") and a beautiful voice like a blackbird, she knows exactly who she is and where she's going, letting the wind and the song of life guide her path.
