Folks who pray or conjure using a foreign language might not always get what they conjure -- prayer or conjuring requires flawless communication.
Latin or any little understood language sounds mysterious and therefore powerful. Yet such disconnected prayer or conjuring works only for those who understand the full meaning of all the words.
By using a native language, the person praying or conjuring is assured that their thoughts and words are precise because only precise thoughts captured in words have power.
