IPA: //haɪˈɜːrədʒi//
KK: /haɪˈɜrədʒi/
A type of sacred work or worship, often involving rituals or ceremonies.
The ancient texts describe various forms of hierurgy practiced by the priests.
Hierurgy is formed from "hieros" (ἱερός) (meaning sacred or holy) and "ergon" (ἔργον) (meaning work). The word refers to the sacred work or rituals performed in a religious context.
Think of 'sacred' ('hieros') and 'work' ('ergon') to remember that hierurgy means the work or rituals that are considered holy.
