The word "zesty" describes something that is lively, exciting, or full of energy. It is often used to refer to flavors that are strong, fresh, and invigorating, like a burst of citrus or spices in food. In a broader sense, it can also refer to a person or situation that is enthusiastic or vibrant.
The word "zesty" comes from the noun "zest," which is derived from the French word "zeste," meaning the peel of citrus fruits, often used for flavoring. It entered the English language in the late 19th century, connoting something that adds interest or excitement.
