and you informal

In informal language, "and you" is a phrase commonly used as a response to someone asking "how are you?" It is informal because it truncates the full question "how are you?" and assumes the other person already knows what is being asked. Here's an example:

Person A: "Hey, how are you?"
Person B: "Good, and you?"

In this context, "and you?" is a casual way to inquire about the well-being of the other person.
