Our mañaina prayed in Spanish - a lot!
I am sure many times some of them did not understand what they were saying, but I do know for a fact that many understood the general ideas of the prayer, and some knew the meaning of every word, especially the short phrases.
One of them was :
Entran los angeles!
Afuera los malignos!
(Let the good angels enter, and stay out you bad ones!)
Of course, Chamorros pronounced these words their own way, which differed from Chamorro to Chamorro.
This short prayer was a blessing for the home, to keep the good spirits in, and the bad ones out; those who cause mischief and trouble.
