Love is any of a number of emotions related to a sense of strong affection[1] and attachment. The word love can refer to a variety of different feelings, states, and attitudes, ranging from generic pleasure ("I loved that meal") to intense interpersonal attraction ("I love my wife"). This diversity of uses and meanings, combined with the complexity of the feelings involved, makes love unusually difficult to consistently define, even compared to other emotional states.

Lust is a craving for sexual intimacy, sometimes to the point of assuming a self-indulgent character. Lust, or a desire for the flesh of another, is considered a sin in the three major Abrahamic religions when indulged outside of marriage.
