Portrait of a Woman Suffering from Obsessive Envy; ThÃ©odore GÃ©ricault. Envy (from Latin invidia) is an emotion which occurs when a person lacks another's superior quality, achievement, or possession and either desires it or wishes that the other lacked it. Bertrand Russell said that envy was one of the most potent causes of unhappiness.
Jealousy occurs when something we already possess (usually a special relationship) is threatened by a third person. And so envy is a two-person situation whereas jealousy is a three-person situation. Envy is a reaction to lacking something. Jealousy is a reaction to the threat of losing something (usually someone). This seems straightforward, and so why the confusion? One problem is an unfortunate sematic ambiguity with the word âjealousyâ (but NOT with the word âenvyâ).
