Juraste comes from the verb jurar, meaning "to swear" or "to promise under oath." It's a strong word that implies a solemn and serious commitment.
In "Vete," the singer uses juraste to recall a broken promise: "cuando me juraste que me amabas" (when you swore to me that you loved me). This word highlights the betrayal and the weight of the unfulfilled vow, making it a poignant and memorable part of the song's narrative.
"Vete" is a breakup song about a promise that fell apart. The singer opens by looking back: the promises, the daily declarations of love, the idea that nothing could ever pull the two of them apart. Now that feeling is fading with every day since the goodbye.
Once it's clear the other person has already decided to end things, the singer stops asking why and simply says: then go. He gave everything, stayed loyal even when people talked badly about the relationship, and got betrayed in return. Rather than begging, he chooses to let go, even if it means drowning the heartbreak for a while.
It's a song about pride after heartbreak: when someone has made their choice, the strongest response is to release them and walk away with your dignity intact.
