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 is also form of fear or suspicion of someone or something that is competing with what they love or desire so both envy and jealously are very closely associated even though they are not exactly the same thing.
