IPA: /ˈɔːrɪfɪs/

An opening in a surface, especially one that leads to a cavity or passage in the body.
The doctor examined the orifice to check for any abnormalities.
Orifice → It is formed from "or-" (from Latin "os, oris", meaning mouth or opening) and "-ifice" (from Latin "facere", meaning to make or do). The word "orifice" refers to an opening or a mouth-like structure, particularly in a biological context.
Think of an 'opening' ('or-') that is 'made' ('-ifice') — that's why an orifice is a type of opening.
