Cách sử dụng
The word 'obstinacy' refers to the quality of being stubborn or refusing to change one's mind or actions even when faced with strong arguments or evidence. It is often used to describe someone who is very determined to do something or achieve a goal, even if it is difficult or unpopular. For example, a student who refuses to give up on studying for an exam despite failing multiple times could be described as displaying obstinacy, or someone who sticks to their beliefs or opinions in a heated debate may be seen as displaying obstinacy. It should be used in formal or serious contexts, rather than in casual conversation.
