Affect is your outward expression of emotions and mood. It refers to how others think you feel as evidenced by your behaviors, like crying or laughing. On the other hand, mood is how you actually feel and is internal. A person's affect is not always congruent with their mood.
Essence, a 48-year-old monthly lifestyle magazine, has a majority-black readership. The magazine focuses on fashion, pop culture, music and black life. It also holds an annual music festival, which was headlined last year by Diana Ross, Mary J. Blige and Chance the Rapper.
Essence is whatever most sums up the heart and soul of something, its truest most indispensable qualities. The essence of Las Vegas is poker chips and dreams; the essence of Johnny Cash is black clothing and country music. Essence can be a physical detail, or, just as commonly, the abstract idea or meaning of something. The essence of Lady Chatterly's Lover might be its revolutionary eroticism, or the essence of religion its devotion to God. Essence can also mean the concentrate obtained from a flower or plant for flavoring.
