Commentary:

This is a word I can’t pronounce. I mean I can but I had to have a friend explain it to me first. That being said this is a great word to use for a fantasy title. Especially for say a foreign character who sets themselves up to be the amazing awesome person, only for your people to learn that they were really just middle management or something similar. Gives your wordy people a sense of fulfillment that they have something over the characters, perhaps. Either way the difficulty pronouncing the word earns it a weird word mention.
