No they don't. Words have meanings. Maybe in this postmodern world where everything means everything, but no. Words have timeless, distinct meanings 

I understand that most likely I am not near as educated as your are, however, I don't beleive that the founding farhers would have went so far as to provide for a Supreme Court  if every word was an absolute.  There would be no reason to have a distinct body to tell the whole country what the founding fathers MEANT when they wrote the constitution. As a young lad growing up I was sure that when a girl said yes, she meant yes. When she said no, she meant maybe. Sometimes I was right, sometimes I got my face slapped.

Just the responces on this thread will surely show that not all place the same meanings on all words.
