drool

You might drool when you're fast asleep or when food smells so good that your mouth starts to water. Babies and dogs are often linked with it, but adults do it too. The word literally means spit coming out of the mouth without meaning to. It is also often used in an informal way to talk about wanting something very much, especially something that looks exciting or attractive. Someone might drool over a new car, a fancy cake, or photos from a dream trip.

The image can sound funny, because it suggests such a strong reaction that a person almost cannot hide it. Think of cartoons where a character sees food and suddenly has spit dripping from their mouth. In real life, actually drooling in public is usually seen as rude or awkward, but saying you "drooled" over something is a normal, playful way to show strong interest or admiration.

To drool most literally means to let saliva fall from the mouth, usually without meaning to. This can happen during sleep, while thinking hard, when looking at or smelling food, or because of certain medical conditions. A baby chewing on a toy, for example, may drool quite a bit.

The word also has a figurative meaning that is very common in informal English. When you "drool over" something, you find it so attractive, delicious, impressive, or desirable that you talk about it with clear excitement. You might drool over a sports car, a rich dessert, a stylish jacket, or photos of a place you want to visit. In this sense, the word does not suggest real saliva. It simply paints a vivid picture of very strong interest.

The link between the literal and figurative meanings is easy to see: when people think about something delicious or tempting, the body may react. Because of that, the word came to suggest a craving that feels hard to hide. It is often playful or humorous, and it usually points to something special rather than ordinary.

So whether it refers to real saliva or to eager admiration, "drool" is tied to strong reaction, desire, and enjoyment.
