How it's used
While this word is technically accurate for biological decay, it sounds quite formal or clinical in everyday speech. Most Hong Kongers prefer using the simpler term 爛 or the descriptive 變壞 when talking about food that has gone bad in the fridge. Using 腐爛 often implies a more advanced or severe state of decomposition, such as a dead animal or a large pile of waste.
Examples
The fruit has been left there too long and has already started to rot.
Related words
Common phrases
rotting and emitting a foul odor
Common mistake
Avoid using this to describe minor damage to objects like a torn shirt or a broken toy, as those should only be described as 爛. It is strictly reserved for organic matter undergoing chemical breakdown.
