Despegué comes from the verb despegar, which literally means "to take off" (like an airplane) or "to detach". It's a dynamic and empowering word that signifies a new beginning.
In the context of "Se Acabó", the singer uses despegué to express a powerful sense of liberation and moving forward. She sings, "Y ahora que despegué nadie podrá parar mi vuelo" (And now that I've taken off, no one will be able to stop my flight), symbolizing her newfound freedom and unstoppable journey after overcoming past suffering.
The song opens on a decision, sung twice before the beat lets go: “Y es que ya no quiero llorar, y es que ya no quiero sufrir” (And I don’t want to cry anymore, I don’t want to suffer anymore), answered in the next breath by “Ahora a mí me toca sanar” (Now it’s my turn to heal). The title arrives as the verdict on everything before it — “Se acabó” (It’s over) — and the verses itemise what that ending cancels: “No tengo que correr más” (I don’t have to run anymore), “No tengo que esperar más” (I don’t have to wait anymore).
What replaces the running is steering. “Ahora soy yo la que lleva el control / De mi propio destino” (Now I’m the one in control of my own destiny), and even the weather turns: “El viento ahora corre a mi favor” (The wind now blows in my favor). The last section is written as take-off — “ahora que despegué nadie podrá parar mi vuelo” (now that I’ve taken off, nobody can stop my flight) — and the thing she spent the song chasing turns out to have been indoors all along: “lo que buscaba está adentro” (what I was looking for is inside).
