Vendaval translates to "gale" or "strong wind". It's a more intense and poetic word than simply "vento" (wind), suggesting a powerful, almost overwhelming force of nature.
In the song, the lyric "Feito um vendaval em mim" (Like a strong wind in me) uses this word to describe the profound and impactful way the beloved person has entered the singer's life, sweeping away solitude and igniting passion. It vividly conveys the intensity of the new love.
"Um Ser Amor" ("A Being of Love") is Paula Fernandes' account of a love that arrives complete and immediately clears away everything that came before it. She sings that her partner "Veio como o dia" ("Came like the day") and "Livre como o vento" ("Free like the wind"), and credits that arrival with ending her isolation: the line "Varreu as nuvens" ("It swept away the clouds") describes loneliness lifting the moment he showed up.
The chorus turns loving someone into a kind of travel to a private country only two people can enter: "É viajar pra terra" ("It's traveling to a land") "Onde ninguém vai amar alguém" ("Where no one else will love that person"). For Fernandes, getting there takes no strategy, only surrender — "É deixar fluir os sentimentos" ("It's letting feelings flow") "E ser capaz de amar" ("And being capable of loving"), ending simply on "Amar simplesmente" ("Loving, simply").
