Cách sử dụng
The word 'puerile' is used to describe something that is childish or silly. You can use it to talk about someone's behavior or actions that seem immature or not suitable for their age. For example, if a grown-up person is acting like a child, you can say their behavior is puerile. It's not a very common word, so be careful not to use it in situations where simpler language would be more appropriate.
