Cách sử dụng
The word 'dullard' is used to describe someone who is slow, boring or not very intelligent. It's not a very nice word, so it's best to be careful when using it. It's often used in a sarcastic or insulting way, so it's not a word you should use to describe someone you like or respect. Instead, you might use it to describe someone who is annoying you or behaving in a foolish way. However, it's important to remember that using insulting words is not respectful or polite, and it's usually better to find a more constructive way to express your feelings.
