How it's used
Primarily used in formal or literary contexts to describe the process of organic decomposition or the metaphorical decline of morals and systems. When referring to everyday food spoilage, native speakers prefer using 變壞 or 變質 instead of this term. It carries a heavier, more serious tone compared to general words for going bad.
Examples
The food will decay quickly if left at room temperature for too long.
Their moral values have decayed significantly.
Related words
Common mistake
Do not use this word for minor food spoilage like milk going sour or bread getting moldy, as it sounds overly dramatic and clinical. It is reserved for severe cases of rotting or deep-seated corruption.
