Jealousy is the malign feeling which is often had toward a rival, or possible rival, for the possession of that which we greatly desire, as in love or ambition. Envy is a similar feeling toward one, whether rival or not, who already possesses that which we greatly desire. Jealousy is enmity prompted by fear; envy is enmity prompted by covetousness.
