KK: /ˈhɛrɪtɪk/
Relating to beliefs or opinions that go against established or accepted doctrines, especially in religion.
The heretic was excommunicated for his unconventional beliefs.
A person who has beliefs or opinions that go against the accepted teachings of a religion, especially in Christianity.
The church labeled him a heretic for his unconventional views on faith.
Heretic is derived from the Greek word "hairetikos" (meaning able to choose) and the root "hairein" (meaning to choose). The term originally referred to someone who chooses their own beliefs, particularly in a religious context, often in opposition to established doctrine.
Think of someone who 'chooses' their own beliefs ('hairein') that differ from the accepted ones, which is why a heretic is someone who holds unconventional views.
