IPA: /ˈkɑːrdɪnət/
KK: /ˈkɑrdɪnəˌleɪt/
The position or rank held by a cardinal in the Roman Catholic Church.
He was elevated to the cardinalate after many years of service.
Cardinalate is formed from "cardinalis" (from Latin, meaning principal or chief) and the suffix "-ate" (indicating a state or condition). The term refers to the state or condition of being a cardinal, particularly in the context of the Catholic Church.
Think of 'cardinal' as meaning 'chief' or 'principal' — the '-ate' indicates a state, so 'cardinalate' refers to the state of being a chief or principal, especially in a religious context.
