How it's used
Focuses on the chemical or biological breakdown of organic matter, making it sound more clinical or formal than everyday terms like 爛. It is frequently used in contexts involving food safety or the deterioration of materials over time. While it describes the process of rotting, it is rarely used to describe a person's moral character, unlike the English word corrupt.
Examples
These fruits have been sitting for a few days and are starting to rot.

Common mistake
Avoid using this to describe physical damage caused by impact or dropping, such as a broken phone or a smashed plate; for those situations, use 爛 or 壞 instead.
