您
Meaning
- you (courteous, as opposed to informal 你)
Example sentence
您学习吗？
Are you studying?
The character 您
您 is 你 with 心 underneath: the polite you, for elders, teachers and customers. It has no plural of its own, so a room of people is still 你们, and slipping back to 你 is a real change of footing.
