This is truly a favorite word! I do use it (perhaps over use it?) in conversation and in my books. It’s not a “big” word, but I’m surprised how often folks don’t know what it means.
(Warning: if you are hippopotomonstrosesquippedaliophobic, you may wish to avoid these posts. 😉)
I began reading at a young age, and wasn’t ashamed that I read whatever I wanted (even if it was “above my grade level” 😲). So it’s no surprise that my stories might have a few “big words.” I don’t consciously try to use bombastic vocabulary (by the way, I learned bombastic from a comic book, thankyouverymuch), but if a word fits the situation or conversation, I’ll use it.
If you haven’t yet read any of my books and are curious about the vocabulary therein, check out either of my series:
Deuces Wild (space opera)
The Sword’s Edge Chronicles (epic science fantasy)
