How to pronounce “quietus” in English

quietus became anglicized. It's not that nice of word.To bring quietus to someone means to kill them.And then it's very close to koi, K-O-I, which is like a Japanese carp.

I found it on the internet in a search engine, basically.It's an archaic French word that means tranquil or quiet, from the Latin root quietus.It hasn't really been used since the Middle Ages.
