I'm writing a novel and I really like using my advanced vocabulary to put in some interesting words. But are some of my words too complex? I'm looking at the ages of about thirteen right though to adults and older citizens. Some of the advanced words I'm using are: Ecstatic, Transmogrification, Reviled, Intrepid, Sprawled and Dispersed. Are these types of words too advanced? Do I need to find some simpler synonyms?
