妒 (dù) is the native Chinese character for the emotion of jealousy or envy, often seen in the compound 嫉妒 (jídù). As a noun, it refers to the feeling of resentment or displeasure at another's advantages or success. This character has a variant form 妬, but both carry the same meaning. In modern Chinese, it is rarely used as a standalone noun, appearing instead in set phrases like 妒忌 (dùjì, 'jealous') or 妒火 (dùhuǒ, 'jealousy').
