This is known as Hippopotomonstrosesquippedaliophobia that term refers to the mere dread of long words. The word is composed of 36 letters and was first coined by the first-century BCE Roman poet, Horace, to deride writers who had an irrational tendency of including many letter in their words. Naming this unique method how we know it was the American poet Aimee Nezheukumatathil who came up with the term as recently as in 2000. 
It's the fear of long words, which is ironic considering how long the word itself is! Imagine trying to tell someone you have that phobia. This term was actually coined to poke fun at writers who use unnecessarily long words. Fun fact: it was named by poet Aimee Nezheukumatathil in 2000! 
Thanks for dropping that fun fact! Appreciate the suggestion, learned something cool today!
