Definition : dead and putrefying flesh (most likely animal)
I found this definition on https://www.merriam-webster.com/dictionary/carrion
I ran into this word in the Cinderella story “THE LITTLE RED FISH AND THE GOLDEN CLOG”. A story from IRAQ
“Then she asked for arsenic and lime, which weaken hair and make it fall out, and an ointment that smelled like carrion”.
This word was used because the evil stepmother was trying to make her stepdaughter smell bad and look ugly so she wouldn’t marry the prince. Fortunately for her it didn’t work and made her even More beautiful.
