Jealousy is a strong feeling that someone has when they think another person is getting more attention or love than they are. It can make people feel uneasy and even angry.
When we talk about jealousy, it's often used to describe how someone feels about their partner being with others. For example, "He's been jealous of his wife's friendship with her ex-boyfriend" means that he didn't like the attention she was giving to someone from her past. We might also see jealousy in relationships where one person is competing with another for attention or affection. In these cases, jealousy can be a major problem if it gets out of control and starts to hurt people's feelings.
Suspecting rivalry in love; troubled by worries that one might have been replaced in someone's affections; suspicious of a lover's or spouse's fidelity.
Example: jealous rage
