How it's used

Used primarily as a bound morpheme in compound words rather than as a standalone verb in daily speech. It carries a strong sense of organic breakdown or moral decline, often appearing in formal or descriptive contexts like 腐敗 or 腐爛. When describing food that has gone bad, speakers usually prefer more specific terms like 變壞 or 臭咗.

Examples

The fruit has been left out for too long and has completely rotted.

Common phrases

to rot or decompose
corrupt or decadent

Common mistake

Learners often mistake this for the word 豆腐, where the character is used for its phonetic value or specific culinary meaning rather than its literal sense of decay. Do not use this to describe inanimate objects like metal rusting, which is better expressed as 生鏽.
