IPA: /ˈkliːnaʊt/
KK: /ˈklēnˌau̇t/
A passage or opening in a plumbing system that allows for cleaning and maintenance, often used to insert tools like a snake to clear blockages.
The plumber used the cleanout to remove the clog in the pipes.
Cleanout → It is formed from "clean" (from Old English *clǣne*, meaning free from dirt or impurities) and "out" (meaning away from the inside). The word "cleanout" refers to the act of removing dirt or unwanted items from a space, making it clean and free of clutter.
Think of making something 'free from dirt' ('clean') and removing it 'away' ('out') — that's what a cleanout means.
