Etymology

Origin of orthodox

First recorded in 1575–85; from Late Latin orthodoxus “right in religion,” from Late Greek orthódoxos, equivalent to ortho- ortho- + dóx(a) “belief, opinion” + -os adjective suffix

Explanation

Orthodox practices or beliefs are generally accepted as true or correct. If you are an orthodox vegetarian, you never, ever eat meat — not like those people who have fish once in a while. When capitalized, Orthodox is the name of the Eastern Church, originally distinguished by its doctrinal differences from the other divisions of the Christian Church. Orthodox is also the name of the branch of Judaism that strictly follows traditional beliefs and customs, derived from orthodox in the earlier meaning of "strictly observant."
