adj. 1. Contrary to or rejecting established religious or cultural doctrines.

Derived from Late Latin haereticus (from Greek hairetikós, "able to choose"), the term originally referred to factional dissent in early Christianity. The root heretic (< Greek hairetikós) implies "choosing" divergent beliefs, while -al turns it into an adjective. Over time, it broadened to denote any challenge to orthodox systems, secular or religious.
