What does orthodox mean?
“Orthodox” describes a belief, practice, or method that follows an established or authoritative tradition. Its strongest everyday association is with religion, where it refers to the form of Christianity or Judaism regarded as traditional or officially correct. More broadly, the word means conventional and widely accepted: an orthodox interpretation may be the standard scholarly explanation, while orthodox medicine refers to established medical practice rather than alternative treatment. The term can be approving, describing what is accepted within a tradition, or mildly critical, suggesting that something is rigidly conventional and resistant to change. Its precise force depends on the context and on whether the speaker identifies with the tradition being described. Historically, the word comes from Greek and literally combines ideas of correctness and opinion or belief, so it names a view regarded not merely as familiar but as properly authoritative.

"The scholar challenged an orthodox reading of the ancient text."

From the Greek roots for “correct” and “opinion,” “orthodox” literally means “having the right opinion”—a reminder that even beliefs once considered unquestioned can be defined as the “orthodox” view.

Where does orthodox come from?
The word comes from the Greek adjective orthodoxos, formed from orthos, meaning “correct” or “right,” and doxa, meaning “opinion” or “belief.” It entered English in the 17th century, initially in religious contexts, where it referred to accepted or authoritative forms of belief. Its use later broadened to describe established methods and conventions outside religion.
