Etymology : It’s true: individuals often see other people’s ideas as unconventional while regarding their own as beyond reproach. The antonyms orthodox and heterodox developed from the same root, Greek doxa, which means “opinion.” Heterodox derives from doxa plus heter-, a combining form meaning “other” or “different”; orthodox pairs doxa with orth-, meaning “correct” or “straight.”
