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.
âGreen with envyâ was a colorful term used long before Mark Twain wrote these words about jealousy in the late-1800s. Today, the saying means that one is envious or covetous of someone or something. If one is âbitten by the green-eyed monster,â itâs thought they are consumed with jealousy. With envy being one of the deadly sins, thereâs been a lot written about it since the beginning of time.
