do you know

Are you informed?

Do you know is a conversational opener that introduces a piece of information the speaker assumes the listener lacks: Do you know there's a coffee shop on the corner?

It also genuinely asks whether someone possesses knowledge: Do you know how to swim?

The phrase often softens requests: Do you know where the bathroom is?

In rhetorical use, it emphasizes a point the speaker finds striking or frustrating: Do you know how long I've been waiting?
