means Excessive pride or self-confidence that leads a person to overstep limits, ignore warnings, and invite their own downfall.

from From Greek hybris, a term originally tied to acts of violence, outrage, or public humiliation inflicted on others out of excessive pride — in Athenian law it could even mean a punishable offense against someone's dignity. In Greek tragedy it narrowed to mean the kind of overweening arrogance, especially defiance toward the gods, that drew down nemesis — divine retribution. The word passed into English through classical education, keeping that tragic shadow: hubris is never just confidence, it's confidence that has forgotten it's mortal.
