Somewhere I had read the translation of the Pali word "Paritta" is referring to "Spell" by Ven. Thanissaro Bhikkhu, but in other contexts, it is referring to "Protection".
For some instances as stated below:
The Group Protection
Katā me rakkhā, Katā me parittā,
I have made this protection, I have made this spell. May the beings depart.
The Peacock's Protection
Imaṃ so parittaṃ katvā
Having made this protection, the peacock arranges his nest.
