Let’s start off with a word related to the business of “longest
words.” Sesquipedalianism is the tendency to use long
words. And, a sesquipedal is a person who has sesquipedalian tendencies.
The word is traced to the ancient Roman poet Horace, who in a treatise on crafting poetry, wrote that in certain circumstances, one must avoid sesquipedalia verba, a Latin construct meaning “words a foot and a half long.” Horace clearly had a sense of humor. (Source-
