妬

Formed as a phono-semantic compound:

女 (woman, female) provides the semantic component.

戶 (door, household) provides the phonetic element.

Originally written as 妒, later the phonetic part changed in form (戶 → 石-like variation).

Thus the character expresses the idea of a woman’s emotions tied to envy or jealousy.

질투 (嫉妬) — jealousy, envy

투기 (妬忌) — envious resentment

In Korea and Japan, the form 妬 is standard.

In China and Taiwan, the older form 妒 is more commonly used.
