Warning: There are some people out there who are dangerous anti-semantics. Like the ones who think “irregardless” is a fine word, and should be included in our dictionaries.
I’m the exact opposite. Words are my world. Consequently, I spend entirely too much time wondering why we pay doctors, dentists and lawyers so much money to “practice,” then allow one of the latter to represent us at a “trial” which also means an “experiment” or a “test.”
