The effect and importance of language and the spoken word in magick

Hello. I was wondering if you could talk about the use of the spoken word and language in magick. And talk about how conquerors changed and manipulated language and the flow of information to assert their dominance and control the subconscious of the masses, and how that has affected the occult and views on spirituality. As well as talk about the spoken word in magick and why it is important.Thank you.
