Some people or societies give certain words special meaning.
They seem to have a power that comes from beyond here and exists
separately from this reality. The belief that there is a
built-in power behind certain words can sometimes cause conflict
among people who each believe the words have power, but disagree
on what it means.
Personally? I do not believe words themselves have power. But
people give words power through their belief that words have
powers independently of the humans that use them. I think this
affects people from all parts of the world, religious,
scientific, atheist, logician, mathematics, etc.
