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.
