Translation guide
In Japanese, expressing jealousy depends on the type: romantic jealousy, envy of others' possessions or success, or even positive admiration. The most common word is 嫉妬, but it's often too strong for casual use. Learners should distinguish between 嫉妬 (romantic/sexual jealousy), 羨ましい (envy), and 妬み (spiteful envy).

Feeling threatened by a rival in love or a partner's attention to someone else.
