Próspero means "prosperous" and is a key word in the traditional Spanish Christmas greeting, "Feliz Navidad y Próspero Año Nuevo" (Merry Christmas and a Prosperous New Year).
While "Feliz Navidad" is very common, Próspero is a slightly more elevated and less frequently used word in everyday conversation, making it interesting for learners. It carries a beautiful wish for success and well-being in the coming year, perfectly fitting the festive and hopeful theme of the song.
"Feliz Navidad" is one of the most beloved bilingual Christmas songs ever written, and this stripped-down acoustic version, featuring Santiago on guitar, brings it back to its simplest form.
The lyrics are wonderfully direct: half in Spanish, half in English, repeating the same warm wish again and again. "Feliz Navidad, próspero año y felicidad" simply means "Merry Christmas, a prosperous year and happiness." The English half repeats "I wanna wish you a Merry Christmas from the bottom of my heart," so the sentiment comes through clearly in both languages.
There's no complicated story here, just a heartfelt holiday greeting meant to be sung together, which is a big part of why this song has become a Christmas standard across both the Spanish and English speaking world.
