I probably wouldn't use adroit, but just because I don't like speaking it. I like words that are more melodic.
I like the word pique. It seems humorous to me. Both those examples only have 6 letters. I don't limit myself to words of less than six letters.
I like words like kerfuffle because it seems funny to me.
I suppose, now that you mention it, I do try to keep around a 6th grade reading level. I wonder if a study would show the reading level of my work has gone down as I've started to make more money on it. That would be interesting!
Thanks for the comment!
