What does the prefix orthodox?

The prefix "ortho-" comes from the Greek word "orthos," which means "straight," "correct," or "right."

It is often used in words to indicate something that is conforming to established or traditional beliefs or practices.

For example:

* Orthodox (adjective): adhering to established beliefs and practices, especially in religion.

* Orthodontics (noun): the branch of dentistry dealing with the correction of irregularities in the teeth.

* Orthography (noun): the study of the correct spelling and pronunciation of words.

So, "orthodox" essentially implies "following the right way" or "being in agreement with the established norms."
