How it's used
This term is primarily used in medical or formal contexts to describe the physical deterioration of tissue. While it can be used in daily conversation, it carries a graphic and serious tone, often implying a lack of proper hygiene or medical attention. It is significantly more specific than general terms for injury like 受傷.
Examples
His wound is so inflamed that it has started to fester.
If you don't take care of the wound, it will easily ulcerate.
Related words
Common mistake
Learners often confuse this with general terms for skin irritation or rashes. Remember that this specifically implies the breakdown of tissue or the formation of an open, rotting sore, rather than just redness or itching.
