Yummy is an adjective that describes food or drinks that taste really good.
When we say something is yummy, we usually mean it's delicious and we want to eat more of it. For example, if someone says their favorite dessert is a chocolate cake, they might add "it's so yummy!" This word can be used in a lot of different situations - when you're trying food at a new restaurant, asking your mom to cook something special for dinner, or even just talking about your favorite snacks. It's a way to express excitement and enthusiasm for the taste of something.
(colloquial, lighthearted, often childish) Delicious.
