ELI5: Explain Like I'm 5

Alleluia, dulce carmen

Okay kiddo, so "alleluia" is a special word that people say in church when they are happy and want to show their love for God. It's like saying "yay God!"

And "dulce carmen" means sweet song in Latin. So "alleluia, dulce carmen" together means "yay God, sweet song!"

It's a way for people to show their excitement and happiness during religious ceremonies, sort of like singing a happy song or cheering at a sports game.
