Long words

My critique groups often lean on me for using bigger words than necessary. Particularly people who read and adore Hemingway. My weak defense is accuracy: I want the reader to get an exact picture. The response is, “in well-written work, sixty percent of the reader’s vision is what the author wrote; forty percent is drawn from the reader’s own experience.” Now with several years and more than several rewrites under my belt, I understand.

So who had the twisted sense of humor to give an exact definition of ‘fear of long words’ as hippopotomonstrosesquipedaliophobia?
