"Festering" Natural Recordings by Native Speakers
The word "festering" refers to a wound, injury, or problem that is not healing or improving and is instead becoming increasingly inflamed, infected, or irritated over time. It can also be used figuratively to describe a feeling of anger, resentment, or bitterness that is building up and not being addressed or resolved.
I apologize, but "fessitude" is not a valid English word. It's possible that it's a made-up or nonsense word, or it could be a typo or a word that is not widely recognized. Can you please provide more context or clarify which word you intended to look up? I'd be happy to help with a different word.
