I’ve begun reading The Way of Kings (The Stormlight Archive) by Brandon Sanderson. It is an epic fantasy novel and very, very good. I highly recommend it if you like epic fantasy.[1]
One of the characters is studying to be a scholar and she uses a word that I must add to my own lexicon. Errorgance.
Whereas, arrogance, is
an attitude of superiority manifested in an overbearingmanner or in presumptuous claims or assumptions
Errogance adds to that, the quality of being totally and completely wrong… or not even wrong.
