What is the meaning of expression you than

The expression "you than" is grammatically incorrect. It seems like you might be trying to say one of the following:

* "You then": This means "after you" or "following you."

* Example: "You go first, and I'll follow you then."

* "You, then": This emphasizes the person being addressed, followed by something happening next.

* Example: "You, then, are the one who will lead the team."

* "You, than": This is grammatically incorrect, but it's possible someone might have meant "you, *rather than*..." which means "you instead of..."

* Example: "You, than the others, are the one who understands." (This is still grammatically awkward, but it might be what was intended).

It's important to consider the context to determine the intended meaning. If you can provide more context about where you heard this expression, I can help you understand what was meant.
