What does zest mean?
Zest most often means lively, enthusiastic energy, especially the kind of energetic interest that enlivens a person or activity. The expression "a zest for life" illustrates this familiar sense, while related uses describe a quality that adds freshness, flavor, or appeal to an experience, performance, or piece of writing. Zest can also refer literally to the colored outer layer of citrus fruit, where aromatic oils give orange or lemon peel much of its distinctive fragrance and flavor. In figurative contexts, the word is usually approving: zest suggests vitality, curiosity, and an ability to make ordinary things more engaging. It works well for both personal qualities and the effects of art, food, conversation, or travel. Because it combines the idea of citrus flavor with the idea of invigorating energy, zest is especially useful when describing something that is lively without being overly forceful.

Where does zest come from?
Zest entered English in the eighteenth century from French zeste, meaning the outer peel of a citrus fruit. Its figurative use for piquant flavor, liveliness, and enlivening quality developed from the citrus sense. The French word is traced to Latin zestum, although the deeper ancestry of that Latin term is less certain.
