Xangô is an orisha, a kind of god from the African Yoruba. It is also the title of a beautiful song that the sender knows. And a music store in Utretcht (the Netherlands), named after Xango "the fighter lover, drum player and dancer who loves music" (as it is written on the back).

This was a completely new word for me. Also it was eatery, suggested by a fellow a-to-zer. I guess that, especially for non-English native speakers, a collateral effect of the A to Z Challenge is the learning of vocabulary. Have you discovered any word this month?
