Hubris comes from Ancient Greek ὕβρις (hubris) 'pride, insolence, outrage'),  or less frequently hybris (/ˈhaɪbrɪs/), is extreme or excessive pride or dangerous overconfidence and complacency, often in combination with (or synonymous with) arrogance. 

The first known use of the word "hubris" in English was in 1884. It was likely a back-formation from the adjective "hubristic" or directly borrowed from the Greek word "hybris".  The spelling "hybris" was more classically correct and began to appear in English in translations of Nietzsche around 1911.  "Hybris" meant "wanton violence, insolence, outrage," originally referring to presumption toward the gods.

Examples of "hubris" used in English:  
"It was a war the republic entered, and stayed in, because of hubris." 
"The terms hamartia and hubris should become basic tools of your critical apparatus." 
"His failure was brought on by his hubris." 
"But hubris seemed to get the better of this team again."
San Antonio Express-News, 16 Mar. 2018.  "Achilles has his heel and his hubris to go along with his great strength." 
"If you accuse someone of hubris, you are accusing them of arrogant pride."
