self-righteous
UK: ˌselfˈraɪ.tʃəs | US: ˌselfˈraɪ.tʃəs
adj. having or characterized by a certainty, especially an unfounded one, that one is totally correct or morally superior
The word "self-righteous" combines "self," from Old English self (referring to one's own identity), and "righteous," derived from Old English rihtwīs (literally "right-wise," meaning morally just). The term emerged in the 17th century to critique individuals who arrogantly asserted their own moral superiority without humility. The morpheme "righteous" itself traces back to Proto-Germanic rehtaz (right) + wīsaz (wise), reflecting a fusion of moral and intellectual judgment. Over time, "self-righteous" acquired a pejorative tone, emphasizing unearned moral certainty.
