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 person who is envious of someone or something can be jealous of what they have and conversely, a person who is jealous can be envious of the same thing or that personâs affection. Either way, jealously and envy are issues of the heart. Envy is ingratitude for what someone already has but jealousy is anger or mistrust over someone or something that is competing with something or someone in their lives. That is why God is a jealous God.
