Long words have always fascinated both layman and logologist alike. No matter that the definitions of "long" and "short and of "words" usually are nebulous or lacking. Many a know-it-all schoolchild has attempted to impress his mates with the incomprehensibleness of the tongue twister ANTIDISHESTABLISHMENTARIANISM as the longest word. Strangely, they never add an S for the plural. The logologist, as a counterdemonstration, would protest that this "word" has never appeared in any edition of the Merriam-Webster dictionaries.
