Etymology or Entomology

Fairly the same thing.  The study of words (etymology) is very much like the study of bugs (entomology).  Let's take the word Fredonia.  There are several United States cities and a municipality of Columbia with the name "Fredonia."  Most surveyors of popular culture will recognize Fredonia as the country Groucho Marx tries to ludicrously defend in Duck Soup.  When Texas tried to secede from Mexico in 1826, they wanted to call their new country Fredonia.  But the true origin of the word dates back to a smear that the British intended to bring upon the newly formed independent colonies, the United States of America.  They thought to give us the back of the hand with the appellation and we received it with pride.  Fredonia, land of the free.  Today, one can read Dr. Diane Ravitch use it as an example in her article Multiculturalism:  E Pluribus Plures.  Words have a way of crawling up inside of things and staying there.
