IPA: //haɪˈrɒfənt//
KK: /haɪˈrɒfənt/
A person, especially a priest, who interprets sacred mysteries or provides explanations of spiritual knowledge.
The hierophant guided the initiates through the ancient rituals with great wisdom.
Hierophant is formed from "hieros" (meaning sacred) and "phaino" (meaning to show or reveal). The word refers to one who reveals or shows sacred things, often in a religious context.
Think of someone who 'shows' ('phaino') 'sacred' ('hieros') knowledge — that's what a hierophant does.
