hubris (n.) Look up hubris at Dictionary.com
1884, a back-formation from hubristic or else from Greek hybris "wanton violence, insolence, outrage," originally "presumption toward the gods;" the first element probably PIE *ud- "up, out" (see out (adv.)) but the meaning of the second is debated. Spelling hybris is more classically correct and began to appear in English in translations of Nietzsche c. 1911.
