腐化
fǔ huà · HSK 7
to become corrupt
🦠 腐化 = rot + transform; decay-ify, turn rotten or corrupt
腐 is the rot/spoiled character (think tofu 豆腐, fermented bean); 化 is the -ify suffix marking transformation. Together: undergo decay, or morally, become corrupt.
化 — person 亻 + spoon/upside-down person 匕
化 is an associative compound showing a standing person 亻 next to 匕, originally a depiction of a person turned upside-down. Together they suggest a figure transforming from one state to another, giving the core meaning 'change' or 'transform'. The character later extended to senses like 'convert', 'influence', and the noun suffix '-ization'.
