There are so many times that I hear words come flying from the mouths of relatively sane people that I have to stop and listen just to make sure that it’s not my hearing that is cuckoo. Words will go wherever we point them.
According to the Oxford English Dictionary there are 171,476 English words in current use. Most of us don’t know and use more than a tiny fraction of that total. Personally, I feel comfortable with dozens of those words.
