Shush is a word used to ask someone to keep quiet.
When people are being too loud or making too much noise, we often tell them to "shush" as a way of reminding them that others might want some peace and quiet. You can say shush in many situations – when you're watching TV and someone starts yelling, or when you're trying to sleep and your roommate is being really noisy. It's like saying "be quiet," but with a softer tone. Some people also use shush as a way of asking their kids to be quieter when they're playing inside.
To be quiet; to keep quiet.
Example: He wouldn't shush so I kicked him.
