A rattle is a loud, high-pitched sound that something makes when it's shaken or moved.
You might hear a rattle coming from an old car with loose parts or a bag of clothes with a few coins inside. People also use "rattle" to describe the noise someone's teeth make when they're hungry or cold. For example, if you see your friend shivering and their teeth start chattering, you could say, "You must be freezing – your teeth are rattling!" In sports, coaches might yell at an opponent to stop racking up points by "rattling" the goal with multiple shots on net.
