A small dish of food or drink served before a meal to make you hungry for the main course.
We ordered a delicious shrimp cocktail as an appetizer before our main meal.
Appetizer is formed from "appetere" (from Latin, meaning to seek or desire) and the suffix "-izer" (indicating something that causes or produces). The word refers to something that stimulates the desire for food, typically served before the main meal.
Think of 'seeking' or 'desiring' food — that's what an appetizer does, it makes you want to eat more.
