IPA: /ˈprɛləsi/
KK: /ˈprɛləsi/
A system of church governance led by high-ranking officials known as prelates, or the collective group of these officials.
The prelacy played a significant role in the church's decision-making processes.
Prelacy is formed from "prelate" (from Latin "praelatus", meaning one who is placed above) and the suffix "-cy" (meaning the state or condition of). The word refers to the state or condition of being a prelate, or a high-ranking member of the clergy.
Think of a 'prelate' as someone who is 'placed above' in rank, and '-cy' indicating a state, so 'prelacy' means the state of being in a high clerical position.
