KK: /ˈɔːstɪəri/
A person who is responsible for opening and closing the doors of a church, often serving as a doorkeeper.
The ostiary welcomed the guests as they entered the church for the ceremony.
Ostiary → It is formed from "ostium" (meaning door or entrance) and the suffix "-ary" (meaning relating to or connected with). The word "ostiary" refers to something related to a door or entrance, often used in a religious context to describe a doorkeeper or someone who manages access.
Think of 'ostium' as a door and '-ary' meaning related to it — an ostiary is someone connected with the door, like a doorkeeper.
