Anhelo means "I long for" or "I yearn for." It's a strong verb that expresses a deep desire or longing for something.
In the context of the song, the singer repeatedly mentions "mi carta que anhelo tu firma" (my letter for which I long for your signature). This word beautifully conveys the intensity of his desire for a final communication, making it a poignant and memorable choice.
This Regulo Caro song, "Aunque Por Fin Te Vas," is a fascinating look at a breakup where the singer is definitely feeling wronged, but also a little bit in control. He tells his departing love, "aunque por fin te vas y a mí me recordarás" [even though you're finally leaving and you'll remember me], implying she'll miss him. He's not exactly begging her to stay; instead, he has a very specific request: he wants her to "escribas una carta para saber el fin" [write me a letter to know the end]. It's almost like he wants a formal closing statement from her!
What's really interesting is how he flips the script. He declares, "yo soy el ofendido" [I am the offended one], making it clear that he believes she's the one who messed up. He even talks about a "carta que corona con distintas flores por el amor y pasión de esa mujer" [letter that crowns with different flowers for the love and passion of that woman], which sounds like he's imagining a beautiful, almost poetic, final letter from her. It's a mix of hurt, a demand for closure, and a touch of dramatic flair.
