What term characterizes a departure from accepted beliefs or standards?

The term "heterodox" characterizes a departure from accepted beliefs or standards by implying a divergence from established doctrines or traditional views. It originates from Greek roots meaning "different opinion," and it is often used in contexts such as philosophy, religion, and economics to signify alternative perspectives that stand apart from mainstream thought.

While "unorthodox" may also suggest a divergence from conventional practices, it tends to be more closely associated with nonconformity in a broader sense, rather than the specific nuance of differing opinions that "heterodox" conveys. "Conventional," on the other hand, refers to something that adheres to accepted norms and standards, making it the opposite of what is being defined.

"Radical" indicates a more extreme departure from traditional beliefs, often advocating for profound change or reform but does not capture the subtler divergence implied by "heterodox." Therefore, "heterodox" best fits the definition of a departure from accepted beliefs or standards.
