i have not known this word, but the root is same as another word which i always use to teach my students. It used to be one of the longest words before the advent of long names for unearthly chemicals. The word is

hippopotomonstrosesquippedaeliophobia. You can break it down as :

hippo poto monstroses quippe daelio phobia.

If you can see, the root is the same as today's word.
