Why this word is great
SURQUEDRY — [Noun] Overweening pride; arrogance. From Old French surcuiderie, from sur- ("over-") + cuider ("to think"), implying excessive self-regard. Unlike "hubris" (which carries the weight of impending downfall) or "haughtiness" (which performs its disdain for others), surquedry is the unshakable certainty of one’s own supremacy. It is the king who mistakes his crown for the sun, the scholar who believes his library contains all truths, or the artist who deems every stroke genius—a blindness not to flaws, but to the very existence of limits, a fortress of conviction built on air.
