I cannot remember the last time I actually opened a dictionary, so I can say it really does not affect my world at all. I don't believe or disbelieve it; it is simply a non-entity to me.
Reminds me of a friend a few years back
who took night classes to learn a foreign language.
After a week or so she called me to chat
and voiced her frustration about the class.
Me: What's wrong, is it turning out to be harder than you thought?
Friend: Yes! They have a different word for everything!!
