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.
A strong feeling of possessiveness, often caused by the possibility that something which belongs, or ought to belong, to one is about to be taken away. The word can be used in a positive sense (e.g., the jealousy of God), meaning a passionate commitment to something which rightly belongs to one. It can also be used in a negative sense (e.g., human jealousy), to mean a self-destructive human emotion similar to envy.
