How it's used

Literally referring to knowing the location or space, this term has evolved to mean having the social awareness or competence to handle a specific situation correctly. It is often used to praise someone for being sensible or to warn someone who is acting out of line. It implies a sense of knowing the unwritten rules of a social or professional environment.

Examples

He knows what he is doing at work, no need to worry about him.
Do you know what you are doing? Don't mess around.

Common phrases

very sensible and aware of the situation
clueless about how to behave

Common mistake

Do not confuse this with simply knowing a physical location. It is strictly about behavioral awareness and situational judgment, not about geographical knowledge.
