Cách sử dụng
The word 'tough' is used to describe something that is difficult, requiring a lot of effort or strength, and sometimes painful. For example, running a marathon is tough because it requires a lot of physical endurance, and studying for an exam can be tough because it requires a lot of mental focus and concentration. It can also be used to describe a person who is able to endure difficult situations and challenges, or a situation that is hard to deal with emotionally. For example, a soldier who has gone through rigorous training is tough, and losing a close friend can be a tough experience emotionally.
